One of three surviving S-39 amphibians of the 21 built in the early 1930s, NC803W flown by the Civil Air Patrol during WW2 on U-boat spotting missions. It was recovered from Alaska in 1963 as a crashed wreck, with restoration at NEAM completed in 1996

Described on the original slide as 'Probably G-ABFN', this would appear to be correct and details of that aircraft are given accordingly. Ex NC806W. Registered G-ABFN 13 October 1930. It was the only British-registered S-39A and was imported by W.Sherwin Cottingham for operation by Personal Flying Services, based at Croydon. It returned to the USA in July 1935, where it was restored as NC806W and converted to S-39B and reportedly later to S-39C, although the USCAR records it as a S-39B, owned by a resident of Anchorage, Alaska and cancelled 20 June 1950.

The S-39 is an American light amphibious aircraft produced by Sikorsky during the early 1930s. This particular aircraft made its first flight in July 1930 and is the oldest surviving Sikorsky-built aircraft. During WWII it was flown by the Civil Air Patrol from Rehoboth, DE on U-boat reconnaisance sorties and occasional SAR flights. After the war it became a bush plane in Alaska but was abandoned after a crash landing in 1957. Fortunately, the hulk was retrieved in 1963 and brought to NEAM, where restoration in its original CAP scheme was completed in November 1996.

Postcard. The aircraft was originally an S-39A and was registered from 1930 until April 1948. Probably the last owner was Ebon L Mason of Springfield, Missouri.

Upgraded from an S-39A. We gather the S-39A did not have the ventral fin. Some twenty S-39 amphibians were built in the early 1930s and mostly sold to private owners despite the Depression. Photo by: Alfred Eisenstaedt / Life

A February 1932 article in Time magazine makes clear the original Air Ferries company in the San Francisco Bay area only operated until the fall of 1931. Walter Varney gave it another try, flying between the 'landing button' at Pier 5 in San Francisco and the Bay Airdrome in Alameda. The 'big' Loening C-2 was replaced by the Sikorsky S-39, a single-engined derivative of the S-38. The fare was reduced to $1, but the air service ceased again in August 1933, several years before the opening of the San Francisco-Oakland Bay Bridge which is blamed for its demise.
