A piece of foam insulation which broke off the external tank and impacted the Columbia’s left wing is officially the “most probable cause” of the the Columbia accident. Hard to believe that it was so long ago, February 1st. NASA built a life sized mockup of the wing and fired some foam into the location they think was impacted on the Shuttle, and blew a 16 inch hole through the wing which is make of carbon composite.
Here’s hoping the Shuttle launches start happening again soon. More patches to collect! I might have to start collecting the Chinese Shenzhou mission patches soon.
