Anyways, after reading the cavalier dismissal by so many here, I now understand why Bubba and Captain, both of whom I liked and respected, were so nonchalant about the "bomb threat". They must have subscribed to the theory that an advertised bomb threat wasn't much of a "threat" after all.
A bit of the Boy Who Cried Wolf, I guess. I don't know, but I've been told, that in the "olden days", often a bomb threat was called in by or on behalf of a stewardess (remember, "olden days"), who was late for the flight, so it would delay the plane long enough for her, oblivious to the trouble caused, to get there. Maybe Bubba and Captain, thought or knew it was something like that?
