Iranian Flight 655 is still generating controversy. According to the commander of the Vincennes, they confused it with a Tomcat F-14A fighter (supplied to Iran by Grumann in the 1970s). They shot it down when they received no response to radio messages. The plane was emitting the typical signal, Mode III Civilian Code, but not Military Code II.

Although the U. S. did not apologize or admit legal responsibility for the blunder, it paid $61.8 million in compensation to relatives of passengers and crew.
