The H-21 was developed in 1949 and five were delivered to the Marine Corps to test as utility aircraft. It quickly earned the nickname “Flying Banana” due to its odd shape. The aircraft is oddly shaped to prevent the rotors from interfering with one another. The designer, Frank Piasecki, was the first person in the United States to hold a commercial helicopter license. Piasecki Aviation changed its name to Vertol in 1956 and is still designing aircraft as a Boeing division. These early helicopters were used as utility and rescue aircraft in the Korean War. They had inflatable pontoons on the wheels allowing the aircraft to land on water. Considered to be the first heavy lift helicopter, a modified HU-21 made the first nonstop transcontinental helicopter flight on 24 August 1956.

The museum’s HU-21B has serial number 53-4326. According to the Air Force Historical Research Agency (AFHRA/RSA), Maxwell AFB, AL, the museum’s HU-21B has the following history:

Unofficial sources state that it was seized during a search warrant drug raid on 13 September 1985. It had been abandoned in the Lake Elsinore area by drug transporters and became the property of the Riverside County Sheriff under Federal Law. It was towed to the museum along public roads early in the morning. It was donated to the museum jointly by the Riverside County Sheriff’s Department and the City of Riverside Police Department in 1991.
