Re: Soyuzes
The very first Soyuz got its main chute entangled with its drag chute. I remember reading that it could have been caused by a too small volume containing the chutes.
Never again, was there a parachute failure in a manned spacecraft (well, except one of the three for Apollo 15).
Later, Soyuz 11 knew a sudden loss of pressure while on their way back.
THey have been wearing pressure suits ever since, but never had to really use them.
That was 32 years ago.
