it was only air to air
Ah!! that explains why the UK knows a thing called an "air to ground frequency" which sounded so incredible to my naive continental ears that I once made a fool of myself by staunchly denying the actual existence of such "air to ground" frequencies.
I must admit that, having visited the UK driving perhaps 50 times over the last 35 years, I regret seeing it become more and more like continental europe - where are the miles and yards, where are the shillings and sixpence, gone is four-star petrol - but aviationwise, it seems to remain a peculiar place to this day. On the longer term I like that very much - nothing worse than to see the whole world turning a uniform grey - on the short term it adds to my reluctance to come flying across.
But of course we are now very far from the fellow aviators that passed away - RIP and my sympathy with those that will miss them.
