This was an accident, plain and simple.

It's too soon to say it's an accident or terrorism. I know we like to have certainty in our lives, but sometimes we must put up with ambiguity until the evidence can be examined and the truth can be determined.

Just joining, sorry if this has been asked before.

Is there any possibility of sabotage with some sort of laser? Given that re-entry is so difficult, vulnerable, and precise, could it perhaps offer just enough interference/heat/destabalization/whatever to impact the shuttle?

ABC News showing what appears to be a recovered liquid fuel rocket exhaust nozzle.

No comment or graphic explaining when or where this was found.

Based on the NEXRAD imagry I would guess the larger pieces will be found in Louisiana.
