I agree with what you are saying, but I think we need a stronger solution to the problem.

>> "If there is a credible threat to a flight, cancel the flight." <<

What if the "intelligence" about the flight is wrong. What if the "intelligence" says flight 93 is threatened, but it is really flight 96 that is the target.

Flight 93 gets cancelled, and flight 96 goes boom.
