re: Weightlessness
Thanks, Raoul. That's right!
And the part which seems uncomfortable to me is the "mummy" style bag, no room to move the legs, and the position of the arms. I'm sure he's either used to it or that's the preferred way to sleep.
I'm quite used to sleeping in much, much smaller spaces than that, but I gave up the mummy-type bags years ago. Miserable.
And thanks again for the pictures. With every picture it's easier to see how things get lost and no one really knows what's up there.
