Money ill spent for no real reason in my opinion. I'd spend the money on an African Safari and a month long dove hunt in Argentina.
At 10 bucks a box for the shells, the money they are wasting would keep me in shells for a long time....or even better I would buy my own airplane and fly again. Something like a Helio Courier or a Maule. The HC wasn't as fast as this rocket...but the landings were a lot easier...even easier than Rocky's Skymasters...
