Not all aircraft need to have any purpose other than fun. Look at people who have Mooney Mites or restored Stearman. Those aircraft are just for fun. Most people that have C-150s and C-172s just use them for fun. A piper cub isn't a useful aircraft, but many people have them and fly them for fun. Anyways all I'm trying to say is that most people I'vbe met at the small local airports just want an aircraft for fun; they love to fly and the aircraft is just what gets them in the air.

Of course Helicopters are better suited to many things, but helicopters are a lot more expensive for a private pilot to own. The autogyro is a lot less complex than a helcopter which is another nice attribute.

Thats right, when autogyros were invented helicopters did not exist. They were the predecessor to the helicopter. They eventually mutated into the helicopter. It's an aircraft that is very responsible for current day aviation and it is not understood by many people.

I guess it all depends what you want from an aircraft. I'm not planning on flying commercially, so I guess I just look at whats fun. I think of aviation as a hobby, something fun I can do with my time.
