There's a lot of guesswork here but...
That piece of paper went from being caught on the door to exiting the shot in two frames. If the astronaut stood "upright " by the hatch I reckon he'd just clip the top of frame, so that's what? 2 meters?
1 meter per frame, 30 frames a second so the "water jet used to achieve neutral boyancy" (Why??? Last time I went diving I managed it with a few weights,) is travelling at 30 meters per second.
Who would believe that? Are they completely deranged?

Yes. Glad I could help.

Want a good laugh and a good look into the "mind" of a conspiracy theorist...? Check out this post over on UM. About half way down that post Turbonium actually suggests that the Chinese might have used superfluid helium to simulate weightlessness and how the fluids extremely low viscosity aided in simulating the way the flag moves in a vacuum. Typical hilarity ensued followed by much handwaving and then Turbo's trademark abandonment of the thread. Cz

Superfluid helium, hmm... Would certainly solve the problem of the astronauts overheating in those bulky suits

So, if the Helium has essentially zero viscosity, would it be possible to swim in it (ignoring the thermal issues)? I suppose it would be like trying to swim in very rarefied air. Does anyone know what the largest mass of helium is that has been cooled below the lambda point? (Edit: I used ellipses twice in one post and it looked silly)

Superfluid helium - errmmm - [facepalm]
And on next week's show, how washing your hair in liquid nitrogen can prevent premature baldness.

If China can hide 100 000 troops under New York City for years I would like to know more about this,(i might have understood it in the wrong way).

Is it just me or wouldn't it be cheaper and easier to "simulate" the space walk by doing it in orbit rather than in superfluid helium?

"Cheer up!" they said, "It could be worse!" So I did, and it was.

Much cheaper and easier ;D

True, but the point is that it was written in advance and we agree that it was sensible to have done so. If you have reports written in advance to cover all of the likely outcomes, it's only a matter of time time before an inappropriate one is released accidentally. If the Nixon administration writes a speech in advance for a contingency, then it's just good thinking. If the Chinese news agency does the same thing, they're typical disinformationists. Granted the Nixon administration did a better job of handing the President the right sheet of paper, but let's not rush to judgment on the writing of the report itself, using a double standard. Granted. But, to me it's the "premonitional" dialog that hurt them here IMO. While we had "speeches" in place for various scenarios I doubt they involved dialog between our astronauts and "ground control." That, to me is a significant difference. Am I wrong here? I can't imagine that china would let it's astronauts say just anything, any "victory speeches" would be carefully scripted.
