| David Hanson , CA | The USS Midway Museum has just added an HO3S-1 (buno 5154) to it's flight deck, though as of April 2015 it is not yet finished. They hope to complete the restoration in about a year. When completed it is believed that it will be the only HO3S in US Navy markings on display in a museum anywhere in the world. 04/03/2015 @ 18:00 [ref: 69013] |
| Kenneth Croxton Saucier, MS | Back in 1968 and 1969 my dad had part ownership in a Sikorsky S-51. Just recently I began to wonder what ever happened to the helicopter. I have found the serial number and the N number that it was assigned at that time. I have run both on the FAA website and it shows that it is still registered to Coast Copters. Coast Copters Inc. has not existed for forty years. The manufacturer's serial number is 51-105 and the N number at the time was 13183. Can anyone help me find this helicopter with this information?

| Lu Zuckerman Pincourt, QC | While in the US Coast Guard I attended two factory schools on the HO3S-1G at the old South Avenue facility in Bridgeport, Connecticut. I maintained and flew in two different HO3Ss 233 and 237 both of which had been originally owned by the Greyhound Bus Company. They proved too expensive to operate and were eventually sold to the Coast Guard.
After leaving the service I attended Michigan State University and eventually went to work for Sikorsky as a tech rep. 05/18/2002 @ 23:39 [ref: 4952] |
