The U.S. Army's CH-47A Chinook helicopter, designed and produced by The Boeing Company's Vertol Division, was used as a standard Army mission to transport the 4,800 pound Lunar Excursion Module (LEM) adapter as part of a joint operation between the National Aeronautics and Space Administration (NASA) and the U.S. Army in the 1960s. Shown above is a Chinook transporting an adapter.
