Vertol CH-21B Workhorse Military Helicopter

Commonly known as the Commonly called the "flying banana" the H-21 Workhorse/Shawnee was designed and built in the early 1950's by Piasecki Helicopter as a tandem rotor Arctic rescue helicopter it soon evolved in to a multi-mission military helicopter, notably by the USAF and the Royal Canadian Air Force (RCAF) to supply their Artic Distant Early Warning radar installations (DEW line). It is of note that Piasecki Helicopter was renamed Vertol in 1956 and subsequent helicopters produced being re-branded as the Vertol CH-21.
