My Siter's exhusband was trained as an astronaut back in the 1990's but he never flew on a mission. He said that when hew was equipped with his personal gear (he was on standby for several missions) they lead him into a room full of all kinds of gear. He said the first two things he grabbed were a SAK Swisschamp (I guess that had the most tools of anyting available) and some duct tape.
He said there were tables full of all kinds of stuff for survival.
