Representatives of fifteen Contracting States and three international organizations met to reassess the operational requirements of the SAM/SAT Region in the light of the problems associated with the introduction of new types of turbine propelled and turbine jet powered aircraft as well as the increasing flow of traffic. After a four-week session, the second SAM/SAT Regional Meeting adjourned on 16 November 1957, having adopted a revised regional plan covering every aspect of air navigation in South America and over South Pacific.


The medal shown here-below, with a diameter of 36mm, was struck on Brazilian colonial copper for the Philatelic and Numismatic Club of Santos, in relation with SANPEX, i.e. Santos Philatelica Exposicao (i.e. Santos Philatelic Exhibition), and commemorates the inauguration of the Museum Santos Dumont and the second SAM/SAT Meeting.

During the 1970’s and the 1980’s, the United Nations issued annually five commemorative medals with first day cancellations for specific events (as part of a UN Medallic First Day Cover program, held in one album per year). The issue was low mintage and all medals were proof quality struck in sterling silver. Specially designed covers, bearing the medal and the matching UN commemorative stamp, were officially cancelled on the first day of issue.


The year 1978 celebrated the 75th anniversary of the first engined-powered flight by the Wright Brothers. This occasion prompted the United Nations Postal Administration (UNPA) to issue on 12 June 1978 two sets of stamps (with US and Swiss denominations) to praise ICAO’s achievements over the past three decades; the subject of the issue was Safety in the Air.  The medal, in sterling silver, proof strike, measures 38mm (1.5” inches) in diameter and was sculptured by Ronald Hower and struck by the Flanklin Mint (Mint mark: "FM").





The obverse depicts two jet planes streaking across the sky as symbols of the many thousands safely flying the international routes.





The reverse shows the United Nations emblem. The outside circle shows the UN name in five languages (Chinese, English, French, Russian and Spanish).
