Interesting drama on a trial of a pilot who shot down an airliner (not real). I recall seeing the interviews with the two American F-15 (IIRC) pilots who were going to crash into the last 9/11 plane to stop it. However, the passengers' actions caused it to come down.
I'd vote to acquit - as the audience did.
