Zeitgebers, I agree that we don't need to publicise all the details of security training for aircrew, especially where it concerns the tactics taught. That said, we should publicise that the training is through and includes all the typical self-defense dirty tricks.
We must include the pasengers. Three or four mostly female cabin crew (unless very highly trained and fit) against young male terrorist types makes pretty good odds for the bad guys. Involving the passengers turns the tables. That's why I'm advocating hijacker reesistance in the seatback cards and safety briefings.
