at 300mph - I'd say a plane hitting a 6" column of water wouldn't be any different than a plane hitting a 6" pillar of concrete.
6 inch column of water stop a plane??? Maybe a paper plane
I recently lent some of my books out or I'd share pictures of P-47s and
P-38s that have hit telephone poles and masts and have rtb safely.
Since the splashes we have now are several feet tall, I'm not sure what
the point is.
