What a nice detail they have considered placing a plaque in honor of the passengers and crew of Flight 93; I had the opportunity to see the film that was created at the root of this event and I think that this still fails to reflect the anguish that these people experienced at that time, it fails to reflect the strategy that was developed by these real heroes of the air and its final decision. Obviously, it is impossible to know how those moments lived inside that flight really were. Thanks for the information @jgullinese. I really did not know it. Greetings.
