NOTE: It is shocking to discover in this new millennium how few people understand the power difference between an Atomic (fission) and Hydrogen (fusion) explosion, but this is probably why so many laugh at any suggestion of surviving an Atomic (fission) explosion unscathed (even though at least one man did so...Twice). To use an analogy, the power of the two explosions are like the differences between that of a cherry-bomb and a hand-grenade.
