De Lackner HZ-1 Aerocycle
Let’s be honest, if it wasn’t for those dual propellers that look like they’d slice us up, we’d probably want one of these. Charles H. Zimmerman, yes, the man behind the Flying Pancake, laid the foundation for the Aerocycle through his system of rotorcraft control.
The United States Army aimed this aircraft as a personal helicopter for infantrymen. The Army believed that soldiers, with no former experience, could learn to operate the Aerocycle in 20 minutes or less. The Army changed their minds on the Aerocycle’s difficulty level after a couple crashes. The Army abandoned the project. Out of the 12 Aerocycles made, only one survives. The Army exhibits the Aerocycle at its Transportation Museum in Virginia.
