Hello Courtney - Happy New Year to you (and all other prunes of course). I was busy over Christmas being crawled over by grandchildren, so not much time for the essentials of life (such as trying to find more info on when and where the next major conflagration will take place - might find the answer in M2's book...or maybe SAM ex 15 is digging out the current intel).
So that's what a nuclear bomb looks like. I used to keep my eyes tight shut whenever I got near one, cos they were very secret back then (and even more secret when I flew in Vulcans); it made getting the SEF key in the right hole a bit tricky, though.
