Bell-47D1 Helicopter - Arthur Young (1945)
By the time the Museum of Modern Art acquired the Bell helicopter that is now an essential part of its permanent display, it was already technologically redundant. It was there not because it represented the latest thinking in helicopter design but because it was the first helicopter ever to have been hung in a museum of art. It had become, in the words of MoMA curator Terry Reilly, "our winged victory".
