Chugaz dear boy!!
And what's all this malarkey about "practical, experienced pilots in the art of low flying"? Any serving or ex serving pilots surely qualify for that epitaph at some time or another, surely?
There are many around, then and now, with whom I would not be happy to sit in the back of their cabs as they flew me around at low level - and so I did not!
Just to tempt your curiosity - I hit something in a cloud whilst flying.........
