I thought that the pilots wore a black one piece UNDER the regular tan outfit to deal with the stresses of G-force when making sharp turns in space?
Personally, I think that a flight suit to deal with REAAAAALLLLYY long patrols would be a good idea, but as to what color, maybe hunter green.
The regular uniform would be underneath, and the G-force underwear would be right next to the skin to insulate against the cold of space, as well as deal with any bodily functions that arise. '
(I should think that it's danged inconvenient to have to take a whiz while on patrol, so there's GOT to be some way of dealing with one's bladder out there.
A closer fitting helmet would be good; the old ones were nice, but a bit too bulky for comfort and tended to shift around a lot.
Just my two cent's.
