action in cabin on the part of terroriests I believe?

John, all of these things have been proposed and discussed at
length by various committees of the ALPA and FAA for as far
back as hijackings have occured. Despite the fact that I was
never an ALPA member (against my religion), ALPA has probably
done more for aircarrier safety than has the FAA. Those pilots
really are concerned about their own butts.
