Vertical and/or short takeoff and landing (V/STOL) aircraft have historically been much less studied than their counterparts that need runways to become airborne. "The V/STOL Wheel is a graphic diagram of all 45 types of aircraft that have been built and tested." While clearly there have been more than that number of models designed and built by many companies, the wheel represents 45 classifications of this highly versatile aircraft. Pictures and descriptions are given for all airplanes and helicopters identified in the wheel. The tail sitters aircraft are especially interesting because of their outlandish designs.
