When we did hijack training in the 90's it was hammered into us that "the safety of passengers and crew is paramount". We were actively discouraged from having a go, or doing anything "foolish".
That has all changed. Any hijacked aircraft must be assumed to be hostile, especially now that a lone madman is very unlikely to be able to take over an airliner. Any responsible goverment must take precautions to protect its polpulace. That the its prime reason for its existance.
Whilst many of us on this side of the pond see armed skymarshals as an unfortunate extension of cowboy culture, it is really only a detail. We can argue furiously, but one hopes logically, about this particular precaution - and others (most of my posts seem to be censored).
However this board appears to be in danger of being hijacked by those espousing extreme views. There are plenty of other places for such rants - this is meant to be a pilots' network. Wittering on about casualities in Vietnam or the conduct of Saddam's thugs is not conducive to a sensible discussion.
