I'm not sure how many have seen the introductory package for air crew on ASOs but I'm not particularly comfortable with the subject coming up and being discussed at any length on a public forum. I'll just say that if they were on board the 717 then I'm bitterly disappointed as I would have thought this was the EXACT situation where they'd be intervening and controlling the cabin in short shrift. If they'r'e not going to intervene in an attempted hijacking, what's the use of having them?!?!?They will have ensured that they weren't compromised only to find out that the aircraft is under someone else's control! Perhaps a review of the material provided to crew who can expect them on their aircraft would provide answers for those who need to know.
