What if the bomber had set it off from his seat?
If events in the film unfolded differently and the bomber set off the bomb before anyone could grab it, would the plane still be able to fly, as Petroni suggested?
If so, then Guerrero's plan might have been flawed from the very beginning, since it all hinged on the explosion bringing down the plane in the Atlantic, which would eliminate all the witnesses and leave all the evidence at the bottom of the ocean. I don't know if the insurance company would still be required to pay off the claim, but the whole thing would still look pretty suspicious.
I also wonder if Captain Demerest was correct when he said that no one has ever gotten away with a stunt like that. Obviously, there are those who have gotten away with blowing up airplanes, but whether it was tied in to any large flight insurance payoffs, I haven't heard.
