I've been really really REALLY wanting to do one of those chopper hog slaughters myself. The problem most have is the expense of it. Running a chopper isn't cheap for one. For 2: You need a really damn fine pilot to execute the maneuvers to keep the clients on the hogs at an acceptable altitude and matching the speeds of the sounders running. I will assume those pilots don't come cheap either. Watch a few of those chopper hog videos to see what I am talking about. I trained many many years ago on Hueys just enough to be able to take off, fly, and land without killing myself and crew for emergency or if a mission went south and there was no other pilot or the pilot was injured somehow. Some of the maneuvers I saw in some of those videos are performed by OUTSTANDING pilots and not something your average Joe with a rotary license would be able to perform.
