BLACK HELICOPTERS ARE A FAVORITE FANTASY when conspiracy theorists and movie directors conjure a government gone bad, but in fact, the last vehicle a secret organization would choose for a stealthy mission is a helicopter. A helicopter is a one-man band, its turbine exhaust blaring a piercing whine, the fuselage ski’s vibration rumbling like a drum, the tail rotor rasping like a buzzsaw.

In the last dark nights of the Vietnam War, however, a secret government organization did use a helicopter for a single, sneaky mission. But it was no ordinary aircraft. The helicopter, a limited-edition model from the Aircraft Division of Hughes Tool Company, was modified to be stealthy. It was called the Quiet One—also known as the Hughes 500P, the “P” standing for Penetrator.

There is no such thing as a stealth helicopter except in Hollywood. The 500P was a LITTLE quieter because it had five main rotor blades. The paint jobs are IR suppresent very dark OD, so they look black at a distance.
I resemble that remark about helicopters shaking, rattling, buzzing and vibrating. Here I thought it was me.
