First Flight Across the South Atlantic from Portugal to Brazil

On this Brazilian cover from Palmeira dos Índios are a set of stamps from 2022 that commemorate the 100th anniversary of the first flight across the South Atlantic Ocean. In 1922 Portuguese aviators Gago Coutinho and Sacadura Cabral used three different float planes to hop to the Brazilian coast from Lisbon via the Canary Islands, Cape Verde and Fernando de Noronha.
