Terminal velocity of bombs?

Was half paying attention to a TV doco on the Dambusters a few mins ago
and thought I heard the narrator say the Earthquake bomb designed by
Barnes Wallis broke the sound barrie on its way down.
Comments anyone?

Methinks you may have misinterpereted something. Iron bombs have the same
terminal velocity as everything else, about 135 mph, IIRC.

How 'bout this

When dropped from (IIRC) 40,000' it was supposed to become supersonic
(original design spec). As it was dropped from a much lower altitude
(20,000'??) it didn't(?).

The Tallboys and Grandslams had a well designed ballistic shape and
could accelerate to these velocities

I think you're the one misinterpreting. Terminal velocity varies widely for
different objects -- it's a function of density, drag, and weight.

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.

Seems to me I heard somewhere that a high altitude parachutist was going
to try and break the sound barrier! Anyone know anything about this?
