|ICBM, ready to go|
First thing I noticed was a number of experiments going totally wrong in the 1940's and 50's. Well, they had a good excuse, it was all new stuff to them and some tests went completely off scale. In the 1960's they were putting these nukes in all kinds of vehicles. There were two particular places you don't want to put a nuke: airplanes and submarines. Guess what! The planes came down, and the subs didn't came back up. Nukes in bombers seemed to be a really big problem.
In the 1970's it became safer to fly around the nukes. However, while keeping their flying stuff high in the sky, their subs went down like bricks. Since the 70's you definitely need a submarine to get in the Nuke Accident Popularity Poll. Accident reports are now becoming rather rare, and I sincerely hope this is not because we don't hear anything about them. All things considered it's amazing that these accidents didn't cause a Third World War. More on this page. Happy Newyear!
