The latest shuttle launch appears to have caused "extensive" damage to Pad 39A. Complete with bits of said pad splashing into the lagoons surrounding the complex, no less. Apparently NASA officials are confident they'll be able to repair the damage in time for the next launch, currently scheduled for October. However, it seems nobody has a clear answer as to why, after some 80+ launches, one of the pads would fail in this fashion.
Update: More detailed pictures can be found here... It would seem the bricks departed with enough force to tear apart a stout-looking chain link fence.
