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.
