My mother had a ride in the R-4 at Sikorsky's plant in Connecticut. It was piloted by Major Gregory the first USAAF test pilot assigned to the Sikorsky plant. As far as I know, the was the first woman passenger to ever ride in a helicopter.

Dear Sir

We are looking forward to locating a H-5/S-51 to add to our museum in New Brunswick Canada. We would like to see what is available to purchase. Can your membership help in our search. We would be greatly apricated. (709) 596-2102,

I'm trying to find out what the fairings on the H-5H were. The two forward ones that seem to be at the rear of the cabin, and the aft ones aft of the engine but forward of the tail boom. These aft ones might have something to do with exhaust.

Looking for a Pilot Operators Handbook (Civl or Military) for this Helicopter. It's needed for a computer Flight sim. I am currently working on the 3D model of it.

En la Republica Argentina estos helicopteros fueron inicialmente adquiridos por el Estado para combatir las plagas de langostas.
En el año 1962 tuve la oportunidad de hacer el curso y volar aproximadamente 100 horas en la Base Oficial de Aviacion Civil.
El riesgo mayor durante su operacion era tocar con el rotor de cola y perder el control total, asi fué como perdimos dos aeronaves y en el incendio sus dos pilotos. otra consideracion importante era aterrizar con velocidad tipo
avion cuando no se habia colocado el lastre convenientemente y de acuerdo a los pasajeros transportados.Un gran recuerdo para mi humilde experiencia de helicopteros en contraposicion a mis 21000 horas de diferentes tipos de avion.

Great shots of this in the movie 'The Bridges At Toko-Ri'

I have a tail rotor blade for this helicopter and am interested in selling it.

I was just writing my grandson to thank him for a tie with P-51, P-38 etc. on it. I decided to tell him about my first helicopter ride in a Sikorsky S-51. A business man from around Rye, NY buzzed our pastures in Old Westbury Long Island and then landed next door. In 1948, I was in 8th. grade and just returning from school, so I ran to the next pasture and the pilot offered three of us a ride. We went up 400 feet and headed east. Immediately I was lost because the trees formed a canopy over Bacon Road. This was great for show and tell in school---and I can never forget Silorsky!!!! My next door neighbor was Albert C. Bostwick who was a partner with John D. Rockefeller in Standard Oil Co. TT

What material were the rotor-blades of the S-51 made of originally? I understand that later they were made of aluminum, but originally something else?

Nick Drummond, e-mail, 09.04.2008 19:15

The importance of this helicopter is often under-estimated, because it only enjoyed a few short years of production before it was superseded by other Sikorsky designs. But its contribution to the development of the helicopter as we know it today was significant. Arguably better known in the UK than the USA, it was an extremely advanced design for its time and a brilliant example of American aero-engineering skill. Moreover, it created an operational blueprint for military helicopters that exists to this day. Its use as Air-Sea Rescue helicopter is particularly noteworthy. During the 1950s, this iconic machine achieved an almost cult status first for rescuing downed pilots in Korea, something which had never been done before, and then off the coast of the UK through numerous rescues of shipwrecked yachtsmen. The S-51's robustness and reliability were impressive given that there were no precedents for the engineering solutions it incorporated. Not all piston-engined helicopters proved to be as reliable. Those familiar with this helicopter have nothing but a deep affection for the old Dragonfly. It was truly a machine that saved lives.

It would be nice if to this paragraph:
Work on the S-51 began in 1943 when the United States Army Air Force put out a requirement for a helicopter bigger and better than the rather crude Sikorsky R-4.
