[Sca-cooks] OT: Space Shuttle disintegrates on landing approach

[Terry Decker]

Probably not.  The O-ring you reference was in the booster, which would only
cause a problem on launch.  More likely, this is a failure of the ablation
shielding.  The tiles that form it have been a weak point in the craft since
inception, but being replacable means not building a new airframe for each
launch.
