oh yeah, we bought 20 B-17Cs and re-named them Fortress Is. 90 Squadron were the only unit in the RAF to use them but were the first to use the fortress in anger, we bought them really just to try out the idea of high level bombing, however there were lots of problems and even people dying on flights due to the altitude, as such bomber command didn't buy anymore and gave up the idea of high level bombing, which is one of the reasons most british bombers had a low ceiling.....................
