The Piasecki H-21 Workhorse/Shawnee was originally developed as a rescue helicopter for both maritime and arctic applications.The counter rotating rotor design dictated the rather ungainly form and earned her the nickname “The Flying Banana”. The last of the piston powered helicopters,she was the first helicopter to make a non-stop transcontinental flight. Beyond her original rescue role, she saw combat action in both the Korean and Vietnam theaters. Her thin skin and temperamental drivetrain would eventually see her succeeded by the C-47 Chinook, but not until almost 20 years of active service. If you would like to see one in the flesh, or a ton of other awesome warbirds, we highly recommend a visit to PIMA Air & Space Museum. Located on the outskirts of the Tucson sprawl it is a scorched desert wonderland for relics of military aviation.
