This sounds like an interesting business idea. It’s from the UK, but could be successful here, too:
What is a gnat? Basically it an airplane just like the ones the big boys in the military use for target practice, but much smaller and specifically designed to be shot at with shotguns.
Imagine it. After a session of shooting conventional clays, a nippy little target plane comes zipping in from the right, shows a flash of belly as it jinks and pulls up into a steep climbing turn. The guns bark and a hit from an ace shot sets off a pyrotechnic charge onboard the aircraft. A huge cheer goes up as the guns reload for another teasing pass, followed by another and another until either the time is up, or the unfortunate target is downed by the sheer fire power.
Once you have shot at the Gnats, plain old clays will seem, well…a little dull.
