The history of the hush-hush helicopter

The Hughes 500P was about as surreptitious as a chopper could be, and in December 1972, it flew a CIA wiretapping mission into North Vietnam.

Helicopters are noisy beasts; it's just in their nature. But for one mission at the tail end of the Vietnam War, a combination of ARPA funds and hard work by the aircraft division of Hughes Tool led to the development of a chopper known as the Quiet One. The Hughes 500P wasn't totally silent, but it was about as surreptitious as a helicopter could be, and in December 1972, it flew in a CIA mission to wiretap a key communications line for North Vietnamese forces. Helicopter historian James R. Chiles (The God Machine) tells the full story of the machine, the men, and the mission.
