I used a clip to slap my "Halloween" piece on:

"La Bomba" – https://www.youtube.com/watch?v=3f0BPosyd1I

I had gone looking for some random creepy video matter to put the music with, and found an old NY Times article that pointed me to the YouTube video. I was already working on the clip snip when I noticed, hey, that was 60 years ago today.

It was originally designed to be 100 Megaton but they got frightened what it might do and they also realized that there was no way the plane dropping the beast could get out of the danger zone in time.
