Most importantly (too me) would it be possible to start one of these on purpose? If you wanted to, what would be a good candidate?
I concluded that the atomic bomb is an excellent choice. I say there never was an atomic bomb. It was propaganda to prevent the US and Soviet Union from engaging in a disastrous WWIII so soon after WWII. And it was very effective but it's time for all the suckers to wake up.
I know you've seen the films. Special effects! Hiroshima/Nagasaki? Regular fire bombing that happened to get out of control because of favorable (or unfavorable) winds! Godzilla? Well that's more difficult to explain but I'm sure if we put our heads together we could come up with something.
Who's with me?!?!?
