Feb. 10--NASA says the insulation surrounding the space shuttle Columbia's external fuel tank was waterproof, but experts say a crack could have allowed heavy rains or humid air to settle beneath the foam and then freeze from exposure to the super-cooled tank.
In turn, the ice-encrusted foam could have cracked and hurtled into the shuttle's protective tiles during the launch, leaving Columbia exposed to deadly heat upon its re-entry into the atmosphere.
Some experts say this could explain how the 2.67-pound, 20-inch foam fragment that smashed into the shuttle's left wing during takeoff might have led to the disastrous ending of its mission last week.
