This is an unusual object on display at the London Science Museum, which offers this explanation:
This invention was made for a man who had lost both arms at the shoulders, an extremely rare injury even among the 41,000 British servicemen who lost one or more limbs during the First World War. For these men, their injuries were so severe that no limb stump remained to which an artificial limb could be attached. In this crude device, a canvas strip which has a pencil attached to a wooden disc at the front was strapped around the chest. Once the pencil was on a sheet of paper, the amputee would write via movements of his torso. This would have been extremely difficult. It was invented by a Major Maclure, an officer in the British Army.
Developed by Goodyear in the 1950s, the Inflatoplane could fit in the trunk of a car, and then be inflated to full size in 10 minutes. The idea was that the air force could drop inflatoplanes to pilots stranded in enemy territory, allowing them to fly themselves to safety. But the project was eventually abandoned because of a series of accidents, and the military's concern that the plane could too easily be shot down. Link: bendbulletin.com
Westerners traveling to Korea in the late nineteenth century were puzzled by this shovel, which they frequently saw in use on Korean farms. It required between three to nine people to operate, but it seemed to shovel dirt no faster or better than a western-style, one-person shovel.
However, the westerners may have been mistaken about the lack of efficiency of the Korean shovel. An article in Esquire (June 21, 2010) by John Richardson offers this piece of info:
When I was a teenager in Korea, the lesson was called Three Men on a Shovel. Koreans used to dig trenches using one guy steering the shovel with the handle and two other guys pulling with ropes tied to the shovel. How Americans would laugh! Dumb Koreans, takes three of them just to dig a hole! Then the Army did a test with three Americans with three shovels against the Koreans, and the Koreans kicked our asses.
In the mid-1950s, Hiller constructed a series of innovative Flying Platforms for an Army-Navy program as a one-man flying vehicle that the pilot could control with minimal training. The pilot simply leaned in the desired direction and the platform would follow. The platforms, which utilized the aerodynamic advantages of the ducted fan, were incapable of tumbling, because if the pilot leaned over too far, the platform would pitch up and slow down.
Unfortunately, the flying platform was plagued by engineering problems. Otherwise, we'd probably all be floating around cities in these today. More info here
