I think it quite likely that our planes shot that plane down over PA. I always wondered why it crashed if the passengers where able to rise up against the terrorists. It doesn't seem like the terrorists would have ditched it unless there was no hope of controlling the passengers, and if that were the case why wouldn't the passengers be able to get the few remaining terrorists away from the yoke? Just speculation on my part, however. Maybe the terrists ditched just out of spite.
