There was a rumor (Never confirmed) that a 4th plane heading for NYC was to be hijacked, but the hijackers either got cold feet at the fact the takeoff was delayed after the other planes had departed or that they did not make it in time to board the plane.
Either way, I would have been mighty pissed off to have landed anywhere else rather that the Big Apple that day. I was on that fourth plane sporting a glorious cold and about to visit the US as an adult for the first time in my life.
Little I knew how the stuff I saw and a decision I made during that trip would change my life. I did feel the in-flight movie was a hint, but never expected it to be that definitive.
