Columbia crew 'had no chance to survive'

Astronauts on the shuttle Columbia were trying to regain control of their craft before it broke apart in 2003, but there was no chance of surviving the accident, a NASA report said on Tuesday.

From the crew's perspective, the shift from what appeared to be a normal descent on Feb 1, 2003, into disaster happened so fast that the astronauts didn't even have time to close the visors on their helmets.

Columbia broke apart about 20 km over Texas as it headed for landing at the Kennedy Space Center. The cause of the accident was traced to a hole in one of the shuttle's wings, which was hit by a piece of falling foam insulation during launch 16 days earlier.
