It was ever thus. This is an extract from a letter my father wrote from Normandy in August 1944.
I have seen many great performances by the AlliedAir Forces, the RAF boys are fairly accurate with the exception of the oddSpitfire & Typhoon who obviously can't cope with the speed of our advanceand give us the occasional strafing---- but those x ------ x Yanks, just drop their load wherethe deuce they think they will and on many occasions they have dropped them asfar as a dozen miles behind the front--- and in daylight at that. Somehow wearen't so enthusiastic about the US heavies and every time much prefer the Lancastersetc. of the RAF, even for close support at night.
By close support at night he meant advancing down a corridor only a 1000 yards wide between areas being bombed by main force heavies.
