Corrected entry: Bones Conway gets a call from a recording notifying him that his unit has been activated. Such calls are made in person, for the simple reason that if a recording was really used, no one would ever admit to getting the message.
Corrected entry: During the bombing, the plane changes from an F-14, to a F-111.
Correction: First Sergeant Williams says after the first bombs miss, that he is sending a backup squadron of F-111's.
Corrected entry: When they make the first glass of purified water in training, the water changes color in between shots.
Correction: It's full of air bubbles which are slowly settling out. That's what causes the color change.
Correction: It is not a recording. A recording would not call more than once regardless of when Bones hung up or anything. The call is made several times by a person, who's only objective would be to say the code, not get on to them or anything, or it would make the call null and void.
