An F15 or F16 could easily have made it to PA to shoot down the plane in the time alloted. Not even a remote question.
Did it? I don't think it even matters. Personally, I think the government should be forthcoming on all matters. I hate being treated like we can't handle the truth. We can.
I'd hate to be the pilot who had to do the shooting, if in fact it had to be done. God bless him. I am not sure I could live with it, even though I believe it would have been the right thing.
The good of the many outweigh the good of the few, or the one. Sad, but reality.
