On February 1st 2003 Space Shuttle Columbia broke up during reentry killing all 7 crew. Commander Rick Husband, Pilot William McCool, Mission Specialists David Brown, Kalpana Chalwa and Michael Anderson Payload Specialists Laurel Clark and Ilan Ramon. The debris recovery operation also claimed the lives of Jules F. Mier Jr & Charles Krenek 20 years on, we've not only solved the problems and moved on to new spacecraft, but learned more about how to make spacecraft accidents of this type more survivable. All of this information is published in the Columbia Accident Investigation Report results: https://history.nasa.gov/columbia/CAIB.html There's also a later Crew Survivability report https://www.nasa.gov/pdf/298870main_SP-2008-565.pdf And Aeromedical Lessons Learned from the STS-107 Columbia Space Shuttle Mishap https://www.asma.org/asma/media/asma/Travel-Publications/NASA%20Shuttle/SP-2014-616.pdf There's also 'Bringing Columbia Home: The Untold Story of a Lost Space Shuttle and Her Crew' which covers stories about the recovery and reconstruction https://amzn.to/3WTmNhq Follow me on Twitter for more updates: https://twitter.com/DJSnM I have a discord server where I regularly turn up: https://discord.gg/zStmKbM If you really like what I do you can support me directly through Patreon https://www.patreon.com/scottmanley
