It's definitely a unique helicopter that was designed to perform acceptably until more advanced aircraft came about. Piasecki seems to have a number of arguably unconventional designs, but if it works well, it doesn't need to be fixed for aesthetics.
Great picture. I worked on those in the late 50s in Hawaii ... and off the island of Hawaii. We drug targets around so they could tune up one of the satellite tracking antennas. Noisy chopper .... carried 19 troops.
Thanks for the replies! Ok, 5 people have voted "It's the ugliest thing on the face of the Earth!" Quit voting for that! The Airbus A380 is the ugliest thing on the face of the earth! Well, that and the Airbus A300ST.
