I hope this doesn't go the way of Flight 800...
I'm leaning more bomb than either sabotage or cat. engine failure.
Some witnesses have said that parts of the wing came off and hit the tail. The flaps on an A300 are huge and are a possibility. This is starting to sound like a one in a million accident. The Bush Administration must have more info than we do because they reopened the airports fairly quickly, they didn't ground departing flights, and no other planes went down, which I would have expected if it was terrorism.
