Quite clearly the RAF wasn't going to risk the priceless Lancaster in such conditions of wind and low cloud and it was courteous of Milly to explain the reason.
The Typhoon mate did well to find a way through vile low level weather en route in order to achieve a fly past in such conditions. Weather in that area has always been difficult and rock-filled clouds are not something to be risked.
Whoever made the announcement that the Typhoon wouldn't be able to make the original time was either misunderstood or had been mis-briefed. Which was a pity; nevertheless the Typhoon pilot should be congratulated.
But the whingeing and moaning from a few vociferous spotters and snappers who weren't able to 'capture' the flypast is unbelievable.
