Sad, pilot failed attempt to eject during airshow crash . .

From ASN; During an air display at the annual Overberg Air Force Base fly-in, the Lightning apparently suffered hydraulic problems. While attempting to return to the field and on a long approach to Runway 28, it crashed in a ball of flame starting a veld fire approximately 3km east of the field. At the time of writing there were conflicting reports regarding an ejection, but the pilot apparently reported that he may have to eject on at least two occasions. He then reported that he was ejecting, followed immediately therafter that there had been an ejection failure. by Jacobus Saayman
