Beach club in Tripoli, Libya 1964. I watched a F105 Thunderchief fly into the sea just off the coast. Not survived.
1981 Somewhere in North German plain watched a Dutch NF5 I was controlling fly straight into the ground. Not survived.
March 1983 Soltau Germany. A Dutch F16 I was controlling had an engine failure right over my head. I heard the surge sounds and the engine rundown very clearly. The pilot ejected with minor injuries. I was so close my Landrover was alongside him when he landed. Took him to the local hospital and he was back flying within a few weeks.
