I’ve always had trouble believing our military accidentally shot it down, but terrorism seems more plausible. It also was an Iraqi national holiday on 17 July.
1. A terrorist looking to shoot down a civilian aircraft flying eastbound out of JFK International Airport never would have been positioned so far east where the flight would normally be flying at an altitude of 30,000+ feet.
2. From what I’ve seen, TWA Flight 800 was flying far below its normal altitude at that point in its flight that night — to make way for a northbound flight into Providence, Rhode Island that was running behind schedule. A terrorist wouldn’t have known this in advance when plotting an attack using a surface-to-air missile.
So it’s not as if the U.S. Navy shooting down a passenger jet is an outlandish possibility.
