I had a quick look through the video, it is only the first ten minutes or so, I think of an hour interview, but if you see the rest of it appearing somewhere I would be interested to know. He mentions air defense. All a guy in a fighter aircraft can do, is fly alongside the cockpit of an airliner and call the airliner on the radio and talk to the pilot. And say instruct him to fly to a military base. If the pilot of the airliner is a hijacker or a regular pilot acting under duress following the instructions of hijackers, if the pilot refuses to accept instructions from the fighter pilot, he has basically three options:
[ 1 ] Follow the airliner.
[ 2 ] Attempt to damage or destroy the airliner, if the fighter has a loaded on board gun.
[ 3 ] Shoot the airliner down with a missile if the fighter has an on board missile.
Now, it may have appeared as nothing more than a number of concurrent hijackings until the first plane impacted. Had it been a normal hijacking, there would be no reason for a fighter to either establish radio contact or face to face visual contact with the hijacked aircraft's cockpit, in fact had it been a normal hijacking, it is precisely what one would not want to do, since for example seeing a fighter draw up alongside might panic the hijackers. America did have a working air defense organization on 9/11 but it was not set up to defend against what happened.
