No, I don't agree the B-29 would've done it ! - The Lancaster would've done it ! - It had proved itself very adaptable for delivering ordinances that no other aircraft could take, including the B-29 - They didn't start on the bomb until 1942, and it took until July 1945, when they first tested it at Almagorda. - July 1943, Arnold ordered starting to modify a B-29, they started the actual mods in December, fitting an H-frame, hoist, carrier assembly and release unit, and the first 'dummy-bomb' tests were in late Feb. 1944 - After further mods, tests resumed in July'44 and by August , they'd fitted both bombs for size and meanwhile had modified a total of 46 'atomic' bombers ; - But it wasn't until July 1945 that they were ready to take-off and A-bomb ! - The decision to A-bomb Japan was a direct result from the B-29's INABILITY to bomb Japan into surrender, CONVENTIONALLY. - A great deal of destruction, yes ! - But no surrender ! - The prospect of losing a million Allied lives to storm the Japanese Islands, was why the decision was then made... But it wasn't on the cards to A-bomb Germany anyway, we'd neutralised their ability to make nukes, and most tacticians could see the beginning of Germany's end from the Invasion of Russia's first defeat of von Paulus...- And it's good to see the old Lancaster these days, the BBME one still flying, G-George in an Aussie museum, and we've got one here at MOTAT in Auckland, [you can do a virtual photo tour in it, on their website...] - So, Lancasters were, INMHO, adaptable to drop a nuke; - might've got their bum singed, but all 'in their stride', just like all their other duties....
