Though we just saw the Garden of Eden sign, we're not in the backyard back home anymore... but off on work assignment, here at the base of the original Trinity bomb tower. They had to lift this first bomb up in the sky to get the proper effect; then did it for real, dropping it down (rather than lifting it up) over Nagasaki, with a clone of the design shown here. The bumpy bomb is vaguely visible, right now, here, see it?
