Return it to germany and detonate?
Ron.
Well don't forget 1.4 million tonnes of bombs were dropped on Germany by the British and American air forces, so they would have an estimated 140,000 tonnes of UXB,s already
And our bombs tended to be a LOT bigger than the German ones as they didn't have the heavy bombers like the allies did !
Yes, absolutely right
My favourite Luftwaffe bomber of 1940 is the Heinkel 111 and this had a maximum bomb load of 4,400 lb. However, when Hitler decided they should bomb London and other British cities instead of bombing the RAF airfields, they had to travel further with a maximum fuel load. That mean't their bomb loads decreased to a maximum of 2,134 lb. This was typical of the Luftwaffe bombers used over Britain, with all having a similar, or even lighter bomb load.
Unlike the RAF Hitler (thank goodness) generally failed to successfully update his bomber fleet from what were 1930 designs, with two engines, thinking that with Blitzkrieg tactics the bombers would strike over short distances in massed fleets. Basically there was the four engined Focke-Wulf Condor flew for the Luftwaffe, but was kept for just maritime use where distances of flights (over the Atlantic) were longer. There was from 1942 the Heinkel He 177 Greif long range strategic, again twin engine, bomber that could carry a 13,228 lb bomb load, but it's numbers were small as it was basically a failure with continual engine failure and structural issues. The Germans never developed them further or increased their numbers for long distance bombing campaigns.
The RAF however developed the Lancaster and from 1942 they formed massive bombing fleets to strike Germany, and the Third Reich generally, had a maximum bomb load of 22,000 lb (equal to the post war Vulcan), but this was reduced to 14,000 when on long distance operations. 1,000 British bomber raids at night, then 1,000 American bomber raids during the day certainly guaranteed the Third Reich was hit hard, although today some revisionist historians pour scorn on this and the morals displayed by the Allies. I say, to quote Arthur 'Bomber' Harris in 1942 when justifying the mass bombing of Germany, "They [the Germans] sowed the wind; now they reap the whirlwind". My London East End Grandmother used to say "Too bloody true!". I will always echo her sentiments.
