A NASA report on the last minutes of Space Shuttle Columbia cited problems with the crew's helmets, spacesuits and restraints, which resulted in "lethal trauma" to the seven astronauts aboard. http://www.cnn.com/2008/TECH/space/12/30/columbia.shuttle.disaster/index.html#cnnSTCVideo http://www.nasa.gov/pdf/298870main_SP-2008-565.pdf The results of this report lay some of the blame on the equipment worn by the astronauts, however the vehicle breaking up as it did was the root cause of their deaths. These poor people did not stand a chance. They died when the spacecraft broke apart. RIP Columbia crew. :cry:
I browsed over the report as it was 400 pages and the end of the day, but it appears that many things did not work properly. Out of this tragedy I hope that great improvements can be made for the safety of future missions.
