De Lackner DH-4.

Along with the flying car, man has been trying to create flying platforms for decades. No notable exceptions will be here, my friends, and so today we visit the DeLackner DH-4 Aerocycle. This was one of many flying platforms the US Army evaluated before the Vietnam era It was a natural instinct to want o out infantry soldiers in the air on three dimensions and give them a newer firing and observation platform. Basically twin counter rotating propellers, each about 15 feet long provided the lift for this “Personal Lifting Vehicle.”
