Another possible answer?
Hello everyone! Someone posted this riddle on another site I frequent, I attempted an answer ... and then Googled to find out if there was a solution somewhere, which brought me here.
More intuitive than logical, the first thing that popped into my head when I read it was "nuclear bomb", the one dropped on Hiroshima. I then ran a search on Enola Gay (the name of the plane that dropped it) and found references to B29 bombers being called birds, and one of "the buzzard squadron". If that's true, there may be a case?
<edited to add: I've just noticed it was Don1 who posted the thread on the other site so if I'm wrong, no doubt he will bring you better answers!
