One of the aircraft also reported a temporary weapons systems failure while the crew was preparing to open fire.Stripped of details, a couple of F4 jets from the Iranian airforce were scrambled to investigate some sightings of lights in the sky. Reports vary, but at least one jet suffered grave electrical failures, tried to fire a missile at something and had something fired at it. A nearby jet airliner also suffered radio failure.
According to U.S journalist Philip J. Klass, it was likely the pilots initially saw an astronomical body, probably Jupiter, an explanation also cited by aerospace researcher James Oberg. Klass wrote that pilot incompetence and equipment malfunction likely accounted for the reported equipment failures.
