No matter what how one has been trained, I recall one fatal accident involving (IIRC) an RAF Jaguar. It was theorised that the pilot was taking his height reference from what he thought were fully grown pine trees - in fact he was over an area of newly planted fir tree saplings, only a couple of feet high.
I also recall the story of another military jet pilot who suddenly realised the "sheep" he had been flying over at very low altitude were in fact white mushrooms.....
