Interesting footage as well, I make no political or social statements, and hope nobody else does as well, it's just a part of aviation history, and an important part IMO. The fact that such a comparatively small warhead to what is in use now sends a cloud up over 25 thousand feet - astonishing, and frightening, both simultaneously. There are lots of little interesting factoids that pop up in the video, I found the deceptive markings on the B29's an interesting tidbit, to try and protect the nuclear armed aircraft from Japanese interceptors.
