Flying along in my PPL days, showing my passenger what was happening with the VOR needle. Looked up. Blue Cherokee coming straight at me head on, both at 2346 ', ' cos I thought nobody else was daft enough to fly at that height. Twanged it hard right, banged the throttle, at exactly the same time as he turned HARD LEFT!!!!!!!!!!.. Was very. very close. That's when I learnt that it is good to talk to people like radar services etc. when the vis is not great.!!!
Whoops. Just noticed should not not have posted on this section. I wasn't Military. Apologies, but someone may learn something from it.
