Comments anyone? Methinks you may have misinterpereted something. Iron bombs have the same terminal velocity as everything else, about 135 mph, IIRC. I think you're the one misinterpreting. Terminal velocity varies widely for different objects -- it's a function of density, drag, and weight. http://www.grc.nasa.gov/WWW/K-12/airplane/termv.html -- Tom Schoene Replace "invalid" with "net" to e-mail "If brave men and women never died, there would be nothing special about bravery." -- Andy Rooney (attributed)
