CAPE CANAVERAL, Fla. - Investigators of the Columbia accident are studying whether pockets of cold air caused foam on the external fuel tank to peel off and strike the space shuttle's left wing during takeoff.
The phenomenon, called cryo-pumping, was found in foam on another external fuel tank that was dissected at Michoud Assembly Facility in New Orleans. The tank was a little newer than the one on Columbia.

The title made me think they were suspecting that the Shuttle hit some "air pockets", or turbulence, which peeled off the foam.
I tagged this on the end of Orbiter thread.

You'd want this stuff to be as homogenous as possible. Differing density will create tensile and shear forces within the foam. Question: would it be ENOUGH of a force?
