Great responses, all, but there seems to be a misunderstanding:
This isn't really about an attack on a shuttle during launch...
This is about two or three shuttles being attacked (firebomb, mine?) while resting in the hangers near the launch site, during preparations, inspections, or repairs.
From what I've found the hangars are all very close to one another and a team of three or four terrorists could make their way inside from the refuge when security is especially lowered (I.e., not on a launch day).
Hope this helps!
