The Vincennes mistook the civilian aircraft for an Iranian Air Force Grumman F-14 Tomcat fighter on an attack run. The Vincennes attempted to warn the aircraft several times but received no reply. However, the warnings were sent on a military frequency to a non-existent F-14 Tomcat. The Airbus crew did not have access to those channels and would not have heard the warnings. The Vincennes fired two missiles which both struck the fuselage of the plane. All 290 occupants on-board were killed.
