Design and Development
In 1958, Sikorsky began designing the S-60 as a prototype "flying crane" helicopter. The S-60 utilized the transmission, rotor system and piston engines from the CH-37/S-56.
The fuselage of the S-60 was a simple "pod-and-boom" design with the engines mounted in side pods and long tail-dragger style landing gear that allowed it to straddle cargoes. The crew cabin was mounted in the nose, with aft-mounted controls for the co-pilot to use during loading and unloading operations. The S-60 had an automatic stabilization system to allow it to hover precisely, using inputs from a sidestick controller. Up to 12,000 pounds (5,443 kg) of outsized cargo such as vehicles could be slung beneath the boom, while passengers and other cargo could be carried in a large interchangeable pod that attached to the fuselage.

Famous quotes containing the words design and/or development:
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
