If they got it right, the military would build millions of them and it would open a new age of military flexibility. Predictions were made that the craft could provide transport to a modern version of the old horse cavalry, providing airborne "eyes and ears" for the Army But like all technological revolutions, it starts with two rivals. The first to submit a bid was Hiller Aircraft, yes the same helicopter aircraft company that came up with the idea to catch the Saturn v rocket with a helicopter - which you can watch on our sister channel escape velocity right now, link down below. It would be called the Hiller VZ-1 Pawnee, and it would simply a direct lift rotor aircraft, with contra-rotating ducted fans lifting a simple platform for one man and equipment. It could carry a person up to 185 lb (84 kg), at a speed of 16 mph (26 km/h, 14 kn) 10 meters above the ground - or 33 feet in freedom units. But they wouldn't be the only company to come up with this idea. The second contender was from De Lackner Helicopters. they were a little slower to the game and their concept was slight more terrifying. De Lackner approached the US army brief with the DH-4. Consisting of a simple cross-shaped frame, it had the pilot standing over the engine that powered contra-rotating rotors. So you know, the pilot was strapped in, i shudder to think what would happen if he were to slip into the blades below. The DH-4 was expected to be able to carry up to 120 pounds (54 kg) of cargo on top of the weight of the pilot, or an auxiliary 5-US-gallon (19 l; 4.2 imp gal) fuel tank to extend its range up to an extra 50 miles (80 km). a cargo lifting line could be threaded through the rotor shaft for the carrying of slung loads underneath the craft. Now I would be lieing if I didn't mention there was third, and only real looking, aerocycle concept to enter. It was called the Bensen B-10 Propcopter and it was pretty unconventional. It was made out of a beam that had engines mounted to each end, with rotors. These rotors had sterring to direct the downwash, linked to a single joytick. But it wasn't selected beyond the prototype stage - and i'm not sure why. so if anyone knows, let me know in the comments below. Prototypes of the other two concepts were built, and then it was time to test them! face off!
