I can confirm that all the Lightnings were camouflaged when Sid was there, we only wore standard flying equipment, we didn't pre-breathe oxygen (unless we were working off a serious hangover, and we just went for it.
We knew the regulator could blow us inside out without pressure jerkins but, if you didn't toggle the mask down, enough of the pressure would leak out the side. You'd be coming down pretty damn fast by then as well, so you didn't have to survive for long!
