WINTERSET EVE

Conventionally, Winter began on the 21^st of December when I was growing up, but apparently there has been a redefinition to make the winter solstice, which happens tomorrow just after midnight EST, or 2100 Los Angeles time, making tomorrow, December 22^nd, the official Winterset.

Interestingly, the term winterset, which was the popular name for the depth of winter for most of my life, has nearly vanished from Google, replaced at the top by towns of that name, schools, and other commercial information. There is on the front page a link to the 1936 movie made from Maxwell Anderson’s Broadway stage play Winterset, which debuted Burgess Meredith. Anderson did a number of screen plays, including Joan of Arc, Mary, Queen of Scots, and other movies you’ve heard of. Winterset is about the Sacco-Vanzetti case. (note)

The whole thing is explained quite well at http://stars.astro.illinois.edu/celsph.html if you care. Interestingly, in Scandinavia and other very cold places, the beginning of Winter is considered to follow All Saints Day, and the winter solstice, Winterset, is considered the depth of winter. Stonehenge was built to mark Winterset and give a dramatic display on sunrise of the winter solstice; from this day on the days get longer, and the northern hemisphere receives more solar radiation, but due to residual effects the climate in most of the northern hemisphere continues to be colder.

Fur bearing animals generally begin growing winter fur when the days are getting shorter, and cease to grow it when the days are lengthening. Sable seems to have ceased growing winter fur, and has shed a lot of hers during warm snaps, but then she lives here in Southern California. She sleeps outside in what amounts to a dog shed, but we’ve had only a couple of nights cold enough to cause her to curl into a ball. A really cold night causes her to curl up into a very tight ball with her tail over her nose. She likes the current weather.

(note) The Sacco-Vanzetti case and the 1927 execution of the two anarchists was an item of discussion well into the 1950’s, and sometimes continues to this day. It is worth study in these days of terrorism and counter terrorism – defenders of Sacco and Vanzetti mailed bombs to governors and there were other acts which today would be classed as acts of terror – although not many study it, largely because it has become fairly clear that Sacco was in fact guilty. Vanzetti may have been an accomplice, but to what degree of involvement can be questioned. Carlo Tresca, the anarchist leader who probably knew, said that Sacco was guilty but Vanzetti was not; but Tresca meant by ‘guilty’ actual participation in the robbery. The Wikipedia discussion of the case is relatively good, and the story of the controversy itself and the arguments made on all sides is worth knowing for anyone involved in teaching or even writing about courts and justice.

I’ve been rambling to avoid discussing the flap over the budget “tax cut” flap. It’s a mess, and it takes a lot of definitions before rational discussion can even begin.

And everyone is weary of a nation that continues to pay bunny inspectors, borrows money from China to send aid to North Korea, and insists on continued raises for highly paid government employees while desperately finding ways to “raise revenue.”

The House rejection of the 2 month continuation of the FICA “tax cut” has sparked a vicious attack on the Republican leadership from the Wall Street Journal, and this from former Speaker Gingrich:

DES MOINES, Iowa—Republican presidential candidate Newt Gingrich says Congress’s failure to extend a payroll tax cut for millions of workers is an "absurd dereliction of duty." His chief rival, Mitt Romney, declined to comment.

Gingrich especially faulted the Senate, saying its decision to adjourn without extending the tax cut for a full year is an example of why the public is sick of Washington and sick of politics.

The Democratic-controlled Senate had voted to extend the tax cut for two months. But the Republican-led House killed that bill and called for opening negotiations on a yearlong extension of the tax break.

http://www.boston.com/news/local/new_hampshire/articles/2011/12/21/feud_between_romney_gingrich_intensifies/

Newt went through all this before, during the budget crisis with Clinton in which the government was actually shut down because Clinton vetoed the appropriation bill. As Newt points out, Clinton rejected the budget, but Congress got the blame, with Newt portrayed as the Gingrich that destroyed Christmas.

The Wall Street Journal says

GOP Senate leader Mitch McConnell famously said a year ago that his main task in the 112th Congress was to make sure that President Obama would not be re-elected. Given how he and House Speaker John Boehner have handled the payroll tax debate, we wonder if they might end up re-electing the President before the 2012 campaign even begins in earnest.

The GOP leaders have somehow managed the remarkable feat of being blamed for opposing a one-year extension of a tax holiday that they are surely going to pass. This is no easy double play.

Republicans have also achieved the small miracle of letting Mr. Obama position himself as an election-year tax cutter, although he’s spent most of his Presidency promoting tax increases and he would hit the economy with one of the largest tax increases ever in 2013. This should be impossible.

http://online.wsj.com/article/SB10001424052970204791104577110573867064702.html?mod=WSJ_Opinion_LEADTop

Note that what was rejected was a two month extension of what is not supposed to be considered a tax cut at all: that is, the FICA payroll payment funds Social Security and is supposed to go into a Trust Fund, and while it is indistinguishable from a tax to those who pay it, it’s said to be a contribution to a retirement fund, a sort of compulsory savings/insurance payment. It isn’t supposed to affect government operations revenue at all; but since Congress long ago set it up so that the money that goes into the Trust Fund is replaced by Treasury Bonds so that government spending can continue to rise monotonically, FICA revenue certainly does affect operations revenue.

The chief effect of the House rejection of the 2-month extension of this tax cut will be political: which party can spin it better? The Wall Street Journal has conceded that the Democrats will win that. Newt, who was the Gingrich who destroyed Christmas, is on record as saying that it’s pretty hard for the House to win a spin battle with the President. I suspect we are about to have another demonstration of that.

Lost in the noise is the fact that a major element of the Senate Compromise was eliminating the Congressional approval of the Canadian oil pipe line. Everyone is concentrating on extending the ‘tax cut’ for 2 months rather than a year, and is ignoring the oil pipeline crisis. At some point the Republicans might notice this. After all, the pipeline is popular even with the Congressional Democrats; it’s only President Obama who is in thrall to the Greens and particularly the liberal Californians, who hates it.

There are a lot of oil pipelines in the United States. See http://www.pipeline101.com/Overview/crude-pl.html for a quick summary. The pipeline at present at issue is about 600 miles long, tiny compared to the hundreds of thousands of miles of existing fuel pipelines, and its environmental effects are tiny compared to what we’re doing now. The Canadians have oil. They need to sell it to someone. They would prefer to sell it to the United States, and presumably the United States would rather pay money for oil to Canada than to Venezuela or Saudi Arabia. Had the pipeline been offered in the payroll tax cut extension it would have passed overwhelmingly.

We need that oil. Obama is refusing to let us buy it. The Canadians are now talking about building a pipeline west to Vancouver. The Chinese would be very ready to buy it.

There are a great number of economic effects in play here. The Oil Cartel would suffer as crude prices fall. Of course they would never pay lobbyists to oppose the Canadian pipeline. We can think of other affected interests, but surely their lobbyists have no influence with the President, who rejects the pipeline because – well, because he can.

And if Obama remains in office in 2013 the Canadians will build their pipeline to the West.

My novel STARSWARM is now available as an eBook on Amazon and elsewhere. The eBook edition contains the Introduction that was in the hardbound print edition but was dropped in later paperback and quality paperback editions. The introduction has some memorabilia about Mr. Heinlein and my mad friend Dan Mac Lean on how the book came to be written. Starswarm is usually classed as a ‘juvenile’, and it was certainly written to appeal to that market, but I followed Robert Heinlein’s rules on ‘juveniles’ when I wrote it: no sex scenes, and as Robert used to say, a juvenile has young protagonists and you can put in more science and explanations of what’s going on in juvenile works; which is to say it’s a good story, and has always appealed to adults as well as to the 10 – 15 year olds it was sort of written for. It has long been one of my favorite books, and I found when I proofread the eBook edition, it holds up quite well on the science including computers. It takes place on a frontier planet and the technology is quite reasonable for such a place. Obviously when an author reviews his own book the recommendation is predictable: Recommended. Also available for Nook. (That may still be in process).

The news media report an uptick in President Obama’s popularity. The payroll tax cut and the Keystone pipeline issues are said to be a part of that, although I am not sure why this makes the President more popular.

I find that the Keystone Pipeline issue is not well understood, and I’ll do a short explanation of it as I understand it when I get back from my walk. Meanwhile Thomas Sowell, who is on my short list of people I pay attention to, has endorsed Newt Gingrich in a short essay on the importance of the upcoming election. He begins with statements I certainly agree with:

If Newt Gingrich were being nominated for sainthood, many of us would vote very differently from the way we would vote if he were being nominated for a political office.

What the media call Gingrich’s “baggage” concerns largely his personal life and the fact that he made a lot of money running a consulting firm after he left Congress. This kind of stuff makes lots of talking points that we will no doubt hear, again and again, over the next weeks and months.

More on all of this when I get back from my walk.

Everyone is speculating about North Korea, which means that no one knows. That includes the US Department of State. One State department official has said that Kim Jong Un’s uncle, Jang Sung Taek, who is married to Kim Jong Il’s younger sister, will be the temporary ruler while Kim Jon Un learns the dictator business. The aunt and uncle were prominently at the public ceremony of homage to Kim Jon Il’s body. There was no sign of Kim Jong Un’s two brothers, one of whom lives in Macao.

Assuming that North Korea is organized and governed much as Stalin’s Russia is, there will be three power structures: Party, Army, and State Security or secret police. They cooperate, but there is rivalry: after the death of Stalin the Army and the Party cooperated to prevent Beria from assuming control of the government, and it was a very near thing, decided when Beria fumbled in an attempt to draw an automatic pistol during a meeting of the Presidium at which Khrushchev accused Beria of being a career hack with no devotion to the Party, and two colonels loyal to Marshal Zhukov came into the meeting room and seized the chief of the secret police. The official story has Beria tried, convicted, and executed in the following weeks, but there is evidence that Beria was shot in the corridor just outside the Presidium Chambers. Beria’s NKVD loyalists were guarding the Kremlin but he had not brought them into the meeting. Apparently North Korea’s story will not be quite that dramatic.

There are no reliable reports of dissent within the Military or the Party. Even less is known about the North Korean secret police. Surely there are technocrats who understand the cost of the dictatorship and the excessive military spending, and the need for economic reforms, but the only sources of information the west has are dissenters, and none of them has ever told a story of any kind of dissent, organized or not. North Korea remains a hermit state, but it seems extraordinarily stable, a refutation to theory of the inevitability of revolt and reform.

Meanwhile, there are reports that a dozen demonstrators have been killed in Cairo as the street mob demands that the military step down and turn over power to someone else. The Army claims that it has not killed anyone. It is not clear who is in charge of the security forces.

We live in interesting times.

Two Days Before Winterset

‘Tis the week before Christmas, my upstairs bathroom is occupied by workmen putting in the new floor, and we slept late. The weather outside is gloomy and chilly, a bad day for Southern California but for most of the United States and Europe it would be called a mild winter day.

Sales of eBook readers including eBook capable Tablets is high and projected to be higher, meaning I presume – hope – that sales of eBooks will be high. This is great news for writers. Whether eBook sales will entirely compensate for the loss of book stores isn’t certain, but I’m pretty sure it will more than compensate. When eBook sales first began to be significant, the attention was focused on their effect on best-sellers, and there was great concern over that; but in fact the biggest effect, so far as I can tell, has been on backlist sales. Mote in God’s Eye and Lucifer’s Hammer were both best sellers in their time. They were reissued a few times, and enjoyed a spike in sales each time, but there wasn’t a lot of steady sale in the past few years. This is presumably because most book stores have limited space for back list books, and what space they devote to the back list comes out of space they could give to mid-list author new books.

With eBooks there is no competition for shelf space between new mid-list books and older books. They’re all available, and the store is always open. Both Mote and Hammer have been selling quite steadily as eBooks, and in fact have now sold more as eBooks than they did in their last print reissues. Other authors can tell the same story.

Good stories have always sold during hard economic times. It doesn’t cost much to wrap up in a blanket and curl up with a good book on a cold gray day. Of course in a bad economy a lot of the story sales were in used books, so the effect on story tellers was indirect, but this year it’s different. The used book stores are dying out just as the independent and mall book stores are vanishing in all but a few fortunate places. There remain the Huge Book Stores and the eBook sellers. eBook readers deliver ever better user experiences while falling in price. The effect has been good for story tellers.

Dear Leader Kim Jong Il has died of a heart attack. North Korea has been far more opaque than the USSR ever was, and apparently we have no idea what happens next. We don’t even know the exact age of youngest son Kim Jong Eun, apparently the anointed successor, nor is there much information about factions or even policy issues. Given what we spend on intelligence it’s astonishing how little we do know about what’s going on in North Korea. World dictators can take note: tyrants with nukes are treated differently from other tyrants, and having a few nukes is a far better insurance policy for yourself and your heirs than having a few hundred million in gold coins. Gold may get you good soldiers, but good soldiers can’t protect you from NATO air attacks even if you denucleated yourself and called the American President “son” and tried to reach out for the extended hand. If Qaddaffi had spent a few tens of millions on a couple of surplus Soviet nukes back during the collapse, he or one of his sons would be in a palace in Tripoli today.

I wonder if the Iranians know this? Saddam knew it, but he was a bit late in applying the knowledge.

So: denucleating yourself will not save you. Signing a peace treaty with Israel and being a military ally of the United States for forty years will not save you. Giving an interview to Barbara Walters may not save you or your sons. http://www.huffingtonpost.com/2011/12/08/barbara-walters-syria-interview-frightened_n_1137591.html The evidence is that having nukes will save you, and may assure the safety and perhaps the accession of your son. We’ll see.

The Wall Street Journal has an op ed piece entitled “Gringrich’s Worthy Brain Pulse” (link) praising Newt for being the only candidate (including the President) who takes seriously the threat of an EMP weapon. While it’s not likely that a single EMP weapon could reduce the United States to a medieval economy, a small nation dedicated to that end might be able to accomplish it with several. The collapse of the world into a new dark age was once a standard theme in science fiction.

Dark ages happen not when you forget how to do something, but when you have forgotten that ever you could do it. The French peasant in the dark ages didn’t even suspect that his ancestors during Roman times harvested nearly an order of magnitude more grain per acre than he could. Part of that discrepancy was climate change – the Roman Warm period was over and the Viking Warm hadn’t come yet – but much of it was lost farming techniques.

Harrison Brown a long time ago in The Challenge of Man’s Future (link and link) argued that it would be harder to reconstruct the Industrial Age than it was to get to it in the first place – that perhaps it would be impossible. I read that book as an undergraduate, and was so affected by it that, when I became President of the Science Fiction Writers of America and put on the annual Nebula Awards show, I invited Professor Brown to be one of the speakers. Building civilizations is not so easy as we imagine.

Whatever Newt’s abilities to decide things every day – and that’s a very tough job if you care to do it (some Presidents don’t) – it would be well to have someone in the presidency who pays attention to ideas like this, rather than someone who laughs at all that science fiction stuff. Or so I have long believed.

Merry Christmas

I spent most of the day moping about thinking of scenes, a bit of time on administrative matters, and then took Roberta out on a date, a nice dinner in a steak house and a movie, IN TIME, I’ve been distracted lately, and I didn’t pay much attention to the trailers for IN TIME on the TV, but as soon as the movie started I wondered if there would be credits for Harlan Ellison and his “Repent, Harlequin, Said the TickTock Man.” On coming home I found on line that Harlan had initiated a law suit, but after watching the picture, settled the suit, so far as I can see without any claims. One of these days I’ll ask Harlan why: it would seem clear to me that under Writers Guild rules Harlan has some claim, at the very least to credit for some ideas in the picture.

Anyway, there was a period in the picture when I thought I didn’t like it, but I got past that and was able to enjoy the story and the acting. As is usual for me I was over-analytic. My main criticism of stories of this kind in which the super rich control everything is that they never have trouble finding loyal minions. There never was a mad scientist who didn’t have a crew of henchmen who followed every stupid order given, and the Timekeeper – TickTockMan – is very loyal to the system. He is clearly derived from Victor Hugo’s Javert more than Harlan’s TickTockMan, but I would be willing to argue the case that Harlan deserves partial credit for the character as well as the Timekeeper title and position. In any event, the social system requires police loyal to it, and there are no obvious reasons for their loyalty given in the film. There seldom is in any of those movies: the mad scientist always has loyal henchmen, and fanatic servants, and enormous resources, but it always risking all that for more on some hare-brained scheme. That doesn’t happen here, but the ostentatious discrepancy between the very rich and everyone else – including their hotel clerks, bodyguards, valets, secretaries – leaves one wondering why the only people with weapons generally employ them in the service of their masters.

But enough quibbling. I enjoyed the movie.

And I’m still moping about collecting scenes for Anvil.

I had this amusing exchange of mail:

Your words are finding a wide audience, and an alternative to the Dean Drive –

Jerry –

When I sent my sister a link to your teleporting cat story, she found that the story had already started traveling around the Interwebs. Since the person who reposted it did not include a link to your site, I took the liberty of adding a link and vouching for your character. If you wish to see it, here is a link to that exchange: http://texasfishingforum.com/forums/ubbthreads.php/topics/6941218/A_simple_microgravity_experime

My working theory about the cat’s ability to teleport is that it simply willed itself in the direction of the safe harbor (the Captain’s chest). Based on that theory, I have developed a credible alternative to the Dean Drive. By the way, my wife said I shouldn’t share the following idea with you because it would end up in one of your stories. I doubt that very much, but if it should happen, you may have it with my blessings. But if you patent an actual working mechanism or a derivative, I get a cut of the royalties and my name goes on the patent with yours. <grin>

Proof of Concept Experiment Design for Dean Drive Alternative: Build a cradle that has at one end a chair for the astronaut/sacrificial victim, and at the other a simple framework that supports a hook. Distance from the couch should be slightly more than double the astronaut’s arms reach. The cradle should be designed to support a significant amount of compression before failing gracefully. (In other words, it should bend under excessive load and not snap off.)

Install the cradle into a vessel, anchoring firmly onto the strongest structural framework available. Place the vessel into at least Low Earth Orbit so microgravity is available. Along with the cradle, launch the astronaut, a cat, and a harness to suspend the cat from the hook at the driving end of the cradle. I suggest placing the cradle relatively near sick bay, or at least a first aid kit for ease of treating any injuries sustained by the astronaut. The cradle should preferably be aligned along the overall vessel’s central axis of mass. Again, care should be taken to ensure that the cradle is firmly mounted to the vessel’s strongest internal framework.

Orient the vehicle so the driving (cat) end of the cradle is pointed AWAY from the intended post-cat-activation direction of flight. Using the vessel’s ordinary means of propulsion (assumed for this experiment to be either a rocket, ion thruster, or similar reaction engine), place the vessel under a sufficient amount of acceleration that the cat does not experience microgravity. This initial baseline acceleration should be along the line between the astronaut station and the cat station, towards the cat.

Place the astronaut in the chair and the cat in the harness. While the astronaut holds the cat at arms’ length, attach the hook to the cat’s harness and inspect all fastenings for proper attachment and locking. This completes assembly of the Feline Drive unit.

Once all other flight personnel have fastened themselves into their seats and all safety checks are complete, turn off the vessel’s ordinary propulsion system. Once acceleration ceases, take inertial readings to verify velocity and direction, then instruct the astronaut to release the cat and move his/her arms into a rest position in the chair. (Care should be taken that the release of the cat does not impart to the cat any additional thrust vectors. If the cat rebounds into the hook area of the cat station, it may consider that area to be a safe harbor, negating the purpose of the experiment.) If the experiment design is followed adequately, the cat will be dangling by the harness in microgravity.

Shortly after the cat recognizes that it is floating, the designer predicts that the cat will identify the astronaut’s chest as a desired landing zone (either from a desire for safety or a desire for revenge). Once this identification is made, the cat is expected to accelerate itself toward the astronaut’s chest at maximum speed by main force of will. The Feline Drive’s hook and harness will transfer the cat’s own acceleration to the drive unit’s mountings to the vessel’s framework, which in turn will effect the acceleration of the vessel. This acceleration should be readily detectible by the inertial sensors.

If this initial experiment is successful, a variety of further experiments should be performed to determine how much acceleration a Feline Drive can produce and for what length of time, whether multiple Feline Drive units operating simultaneously can increase acceleration, and whether other factors can increase acceleration. This last alternative presents an interesting possibility for an additional experiment that could validate the Feline Drive, if the initial experiment fails.

For this alternative experiment, add an additional station that extends the cradle forward from the cat hook station. In the new station, affix a hook and a large dog in a harness. (Sable might be interested in applying for the job.) Place a removable blind between the dog station and the cat station. (Care should be taken to ensure that the cat never sees the dog.) If the initial exposure to microgravity does not cause the cat to will itself into acceleration, the astronaut pulls a control that drops the barrier between the dog station and the cat station. (Care should be taken to ensure that the cat sees the astronaut take the action that drops the barrier.) The sudden appearance of the dog should cause the cat to consider the astronaut as both safe harbor (away from the dog) and as an essential target for revenge, thus maximizing the cat’s focus of will to move toward the astronaut. In short, the astronaut causing the sudden appearance of the dog is expected to crystallize the cat’s attitude into the incontrovertible belief that, in microgravity, "The enemy’s chest is down."

Once the Feline Drive concept is validated, it is predicted that additional experimentation can be designed that will uncover the principles underlying the force of will. Further research along those lines should determine whether it is possible to produce an inorganic Feline Drive equivalent.

I replied “You’re quite mad, aren’t you?”

To which he replied

Interesting question. If I were truly mad, how would I know?

Fortunately you’re not the first to wonder that about me. Been tested.

Not mad. Don’t even have to take meds. Well, not for *that* sort of thing at least. I just work as a government contractor in IT, so I have a lot of creativity that doesn’t get used at work. I spend the bulk of my time helping pave the way for replacing a mission-critical, absolutely essential, enterprise data collection app that is written in FoxPro 2.6 for DOS. And once we get the data out of the DBFs and into a real database (SQL Server 2000, running on a Win2K server), the architect over that side of things determined many years ago that we would not have SQL Server enforce our primary key/foreign key relationships because that would slow things down too much. Better to do all referential integrity in the code, after all. So we have around 500 tables with a total of 12 foreign key relationships defined in the DB, which all exist within the scope of 5 tables. All of the other hundreds of relationships that exist are maintained solely in code. Or they’re supposed to. I’m not aware that we actually have any way to test that assumption.

I enjoy thinking through these kinds of intellectual thought experiments. The way I figure it is, I will either come up with a brilliant idea that makes me a fortune, or else I’ll win an Ig Noble.

Or become a character in a Discworld novel. And none of those seem like really bad outcomes. After all, I work as a government contractor in IT. Occasionally these kind of flashes of twisted inspiration have resulted in useful ideas that have been implemented at work. But none of them have involved felines.

So I gather that you don’t think the Feline Drive would work? Or were your objections based more on opposition to gratuitous cruelty to astronauts? I suppose that would be valid. Perhaps we could design around that (flak vest or some such), but I am concerned that anything that might cause a cat to think its desire for revenge could be thwarted puts the whole project at risk. After all, I’ve never met anything that can take a more creative approach to revenge than a cat, and they generally seem willing to take the long view towards getting it. Since we want the cat to use its unorthodox locomotion ability, we would not want to give the cat any idea that it would not be able to cause maximum harm at that instant, otherwise it might put off attaching itself to the astronaut.

I realized while writing this that while you said "teleporting" I had jumped to the conclusion that it was most likely to be a reactionless drive rather than teleporting. I have seen cats and dogs who levitate onto the furniture. They always jumped, but never seemed to put enough effort into it to achieve that altitude they reached. One cat of my acquaintance also never seemed to have the velocity he needed to reach that altitude. I never saw him and his brother both jump onto something at the same time so I had no external velocity to gauge against, but he *always* looked like he was moving a little too slowly for the altitude he needed to reach. Either way, the experiment I outlined would identify if the cat was moving by means of teleportation or a reactionless drive. If teleportation, the cat would dematerialize from inside the harness and re-materialize on the astronaut’s chest.

Perhaps I should take advantage of the rest of the weekend to write up the Feline Drive idea in a more formal framework and see if I can’t bag that Ig Nobel after all.

Now, about the cat flight film. If it was recorded as part of an Air Force-funded flight, the film is likely to have been archived somewhere and that means it could be acquired through an FOIA request.

Or possibly one of the other members of the Human Factors staff (or their successors) would have it. If you still have any contacts in that area, perhaps they might have a clue? I think you could be assured of an instant viral video hit. I could think about it for a while and try to come up with an angle for capitalizing on that, but I don’t know how well any such ideas might be received. <grin>

–Gary

I can only say that I have tried to find a copy of that film, and haven’t been able to do it. I last saw it at a conference at Randolph Field probably thirty years ago. It was made about fifty years ago, and I don’t know that more than one copy was ever made.

I agree that “reactionless drive” may be a more inclusive description of the cat’s motive power than teleportation. Whatever allowed it to travel, claws extended, from midair in the cockpit to the chest of the pilot is not at all visible, and this would not be the direction we would have predicted an inanimate object would go at that phase of the flight.

I haven’t any firm opinion on the motivation of the cat. I do know that no pilot who has seen that film has ever been interested in replicating the experiment.
