yQ6we TIL of Dr. Story Musgrave, a NASA astronaut who made history on STS-80 by not getting into his seat before re-entry. He instead stood up on the flight deck "surfing" the Space Shuttle while it decelerated from 17,000mph to 0mph. He is the only person to have seen re-entry plasma with his bare eyes.
awgML TIL Astronaut Gus Grissom was accused of prematurely blowing the hatch on the Liberty 7 space capsule, causing it to sink. He maintained the hatch blew on its own without his intervention. He later died in the Apollo 1 capsule fire because of a complicated hatch that would not blow quickly enough.
