As I said in an earlier thread the biggest risk now is getting shot by the "good guy", be he an F16, sky marshall or the other pilot.
Actually, getting shot by the other pilot isn't currently a risk, since we are unarmed.
There is also the risk of the bad guys overpowering the sky marshall (as unconceivable as that may seem, since he's trained
!) and taking his gun. At least we'll die quick........
