Chinese Spy Balloon

[ClydeR]

If I dumped a bag of pennies from 60,000 feet, the pennies would still be harmless. I know this because I didn't use elementary math.

I saw that episode of Myth Busters too! Very good. But you fail to understand that terminal velocity has no practical application to very heavy objects, like whatever was the size of three buses attached to that balloon. Further, you would not want to be hit by a penny traveling at its terminal velocity, even if it did not kill you.
