There are apparently two crash sites, one where the engine hit, one where the rest of the plane hit.

If true, this clearly points towards terrorism.

ABC reports Pentagon had no advance knowledge, saw it 1st on t.v.

No it doesn't. It just means that the engine came off before the plane crashed.

Re: Bomb theories. I would think it difficult to plant a timed bomb because with airport delays and all you wouldn't know when it would go off. So I would discount that possibility. Maybe a radio detonator but I don't know about ranges. Right now I would guess that it is unrelated to terrorism simply because no other planes have gone down yet. OBL tends to work in rushes.
