10 Worst aircraft accidents and incidents

The Navy hailed the airplane seven times on a military frequency, which it could not pick up, then three times on a civilian frequency. The crew of the Airbus may have thought these three calls were directed towards another Iranian aircraft, that one a military surveillance airplane, that had recently been in the area. As the airbus appeared to dive towards them, the Vincennes finally fired two missiles that both hit the airbus. Iran does not believe this was an accident and insists that, even if it was, it was caused by recklessness and is therefore an international crime. One explanation for the accident is a psychological expectation to see a fighter plane after the gunboat battle and then to see it dive to attack; there were also confusion with the transponder codes that made it temporarily appear to be broadcasting a military code. The United States has never formally apologized for the accident.
