The audacious rescue plan that might have saved space shuttle Columbia
I was reading this last night. Obviously it was developed in hindsight, but it’s fascinating to see everything they would have had to do, and everything that would have had to go *exactly* right to reach Columbia before the crew succumbed to CO2 poisoning after a month in a craft that had been prepped for a mission less than half that time. Error margins are slim to nonexistent, and the time crunch would have put the rescue crew at risk as well. (via Slashdot)
