“Body blading (also known as buggy rollin') is an extreme sport that involves descending down a slope while wearing a flexible aerodynamic plastic roller suit that has wheels on the feet, knees, torso, and arms. This suit was created by Jean-Yves Blondeau, and he is one of the premier body bladers. Body blading is similar to roller blading, and in fact a body blader often starts out using the rollers on their feet in the same fashion as roller blades in order to gain initial speed, but then the rider generally assumes a position laying on the stomach facing down the hill. A body blader is capable of reaching very high speeds. Maneuverability is achieved by moving the body into various positions to change direction”. – Wikipedia

Number 10. BELL H-13 SIOUX was a two-bladed, single engine, light helicopter built by Bell Helicopter. Westland Aircraft manufactured the Sioux under license for the British military as the Sioux AH.1 and HT. In 1947, the United States Air Force ordered the improved Bell Model 47A. Most were designated YR-13 and three winterized versions were designated YR-13A. The United States Army first ordered Bell 47s in 1948 under the designation H-13. These would later receive the name Sioux. The Bell-built H-13 B is seen airborne in this April 29, 1951 photo. The helicopter is equipped with a 173 horsepower engine, cruises at 85 miles per hour, climbs 900 feet in a minute and has a service ceiling of 11,500 feet. (Photo by AP Photo)
