Reports from First flight across the South Atlantic Ocean in 1922

This original and unique document comprises two reports, one by Captain Gago Coutinho and the other by Captain Sacadura Cabral, both deriving from the first flight across the South Atlantic Ocean, in 1922, by floatplane, with only internal means of navigation (the Coutinho-invented sextant with artificial horizon) from Lisbon (Portugal) to Rio de Janeiro (Brazil). This event is an important landmark in aeronautical history, and marks the use of the sextant in air navigation for the very first time. It reflects the courage and bravery of the Portuguese in "conquering airspace", almost 500 years after the discovery of Brazil.
