Air Mail Issue 201807-Seawings

RC 201807 - Air Mail - Seawings

As a complement to the 2017 series of definitives, an Air Mail series was issued in July 2018. Historic flying boats, also called seawings, were selected as a motive as they are an important part of the postal history of intercontinental Air Mail. Similar to the 2017 definitives, the stamps display the country name "Capricornia" and "FM" for the Federated Micronations. Three double sheets with se tenant pairs were issued, combining the CW 0.50 / 1.00, the CW 1.50 / 2.00 and the CW 3.00 / 5.00 stamps.

  • CW 0.50: Saunders-Roe SR.A/1, an experimental jet engine powered flying boat designed as fighter aircraft. First flight took place in July 1947 but the project was ended in 1951. It never entered military service as the demand for this solution was very low.
  • CW 1.00: Dornier Do-X, in its time the largest plane built, with 6 twin engines. First flight took place in July 1929. The flying boat was able to carry 66 to 100 passengers and cross the atlantic. 3 exemplaries were built, two of those sold to Italy.
  • CW 1.50: Sikorski S-40 "Caribbean Clipper", a flying boat operated by Pan American as part of their "Clipper" fleet. The "Caribbean Clipper" NC81V had its first flight in November 1931. The S-40 was able to carry up to 38 passengers.
  • CW 2.00: Martin M-130 "China Clipper", photographed in front of the Golden Gate Bridge in San Francisco. The "China Clipper" was operated by Pan American and used on the trans Pacific air mail route. In January 1945, it was destroyed during landing at Port of Spain, Trinidad & Tobago.
  • CW 3.00: Martin M-156 "Soviet Clipper". A larger variant of the M-130, it was rejected by Pan American which selected the Boeing 314 flying boat instead. Because of this, the "Soviet Clipper" was sold to the Soviet Union in 1937 and operated by Aeroflot on its far east routes until 1944.
  • CW 5.00: Hughes H-4 Hercules "Spruce Goose", a flying boat designed as strategic transport plane. Its sole flight took place on 1947.11.02. It is now on display in an aviation museum in Oregon. Until 2019, it was the plane with the largest wingspan, 97.8 m.

The price of the full set is CW 13.00. It can also be ordered as gutter pair set, as described above.
