First aerial crossing of the South Atlantic

The first aerial crossing of the South Atlantic was made by the Portuguese naval aviators Gago Coutinho and Sacadura Cabral in 1922, to mark the centennial of Brazil's independence. Coutinho and Cabral flew in stages from Lisbon, Portugal, to Rio de Janeiro, Brazil, using three different Fairey III biplanes, and covered a distance of 8,383 kilometres (5,209 mi) between 30 March and 17 June. Although the North Atlantic had already been traversed in a non-stop flight by John Alcock and Arthur Brown in 1919, Coutinho and Cabral's flight remains notable as a milestone in transatlantic aviation, and for its use of new technologies such as the artificial horizon.

In June 2022, the centenary of the first aerial crossing of the South Atlantic, it was announced that Faro Airport will officially change its name to Gago Coutinho Airport, in honour of Carlos Viegas Gago Coutinho.
