Not only the 8th Air Force.
Leeming (RCAF) 1945, bulldozed Halifax remains (subsequently uncovered around the Northern HAS Site during construction) into a pit dug for the purpose.
The Ground Radio guys, in the late '70's, poking about, uncovered a complete .303 machine gun. Having lovingly restored it on the night shifts, presented it to the Armoury. The Duty Armourer was stunned to say the least.
Chatting to Canadian ex-aircrew, revisiting Leeming in the '70's,they told stories of bombs 'cooking' whilst being loaded and being dumped into Bedale Beck. This went on for 3 years.
I stopped fishing Bedale Beck as soon as I was told.
It must be the most explosive stretch of water in Yorkshire.
