The RAF has played its part in defending our island including the bit you live on.
The RAF was made up of many people of many nations in WWI; British, Canadian, Australian, Indian, Irish, New Zealand, and never forgetting Polish.
The 'Britain alone' rubbish was never more thwan a myth.
And, yes, these were brave young men.
That was seventy years ago.
I fail to see why a fly-past of 100 planes in front of an unelected anachronism is in any way fitting.
By all means have a commemoration: I'd have thought ariel displays, static displays, demonstrations by the RAF regiment, etc, and a fly past above the national Arboretum more apropriate.
We rightly commemorate the war dead at various war memorial each November; as a matter of fact, thanks to painstaking research, we are adding 21 names of those who fell in WWWi but whose names are unrecorded, to ours; but I think something different than the same old fly past down London's Mall would have been better.
