Comments anyone? Methinks you may have misinterpereted something. Iron bombs have the same terminal velocity as everything else, about 135 mph, IIRC. Think a bit about how gravity works and what "terminal velocity" actually *is*. A human might fall about that fast because of their density and drag. And that's at low altitude. Someone bailing out at high altitude where the air is thinner will fall much faster. Something with less drag or higher density will too.
