coccinelle, sorry have only just returned to this thread. Yes I saw the bombs explode, I was in the RAF and was sent to the middle of the Pacific, 1000 miles south of Hawaii [that was another wow factor] to what was then Christmas Island. The American wanted to carry out their tests and "borrowed" C I for 8 months, the first bomb was quite small by atomic bomb standards but each one got bigger and the final few were huge. The first one was quite scary as we didn't know what to expect but we gradually got used to them, they were an awesome sight.
