Gnat shoot

That looks like fun.

You'd probably have to have a lot of air in front of one of those little planes to hit it.

Best way to describe it...

Closest I've ever come to the shots in that video is shooting mallards on a flyway as they came past full bore at what looked like 60 mph, typical shot about 25 - 30 yards and the ducks gaining speed as they followed the ground over the top of a hill and then back downwards again.

That required about four feet of lead space with BlackCloud shells (1400+ fps). The shots in the video look like more distance than that and I assume nobody's going to let the shooters use BlackCloud shells on their airplanes.
