回答: VERY GOOD QUESTION。 由 NF 于 February 06, 2003 18:43:37:

My second thought was neither faulty heat tiles nor the insulation breaking over the wing on launch had anything to do with the tragedy.Could it be just a one-time accident, since the shuttle was in its 28th mission. 太空还是充满险境。那些勇敢的宇航员们为了人类宇航事业的发展而舍身忘死,值得敬佩。
