Sikorsky CH-3E
DAYTON, Ohio -- Interior views of the Sikorsky CH-3E Black Mariah on display in the Southeast Asia War Gallery at the National Museum of the U.S. Air Force. The museum's CH-3E -- known as Black Mariah -- is a veteran of the Southeast Asia War. In 1965 it was attached to the 20th Helicopter Squadron. Painted flat black (hence the nickname), it was used for highly classified special missions. (U.S. Air Force photo by Ty Greenlees)
