I think there is a new truth that hasn't really been widely considered- Airline Hijacking is a thing of the past. Not only because of new security measures, but, because a terrorist can no longer wave a knife or Gun in the passengers faces and intimidatingly tell them "don't do anything stupid and you'll be OK." No one believes that anymore, Passengers will respond like cornered animals fighting for their lives. The downed plane in Pittsburg was a result of knowing what the other planes had been used for, you don't need a cell phone to know what those planes were used for now.would be Hijackers are likely to not even try , and if any do they willmore than likely be stopped, if not by the Passengers and crew , then they are likely to meet jet fighters with orders to fire. I Bet no one Hijacks an airliner for at least 20 yrs, The Passengers and crew have the upper hand now, They outnumber the hijackers and they will consider themselves already dead if they don't take action and attempt to overtake the hijackers.Hijackers depend on intimidation to control the situation you can't intimidate people who see stopping you , at any cost, as their only hope of survival.
