José Manuel Sarmento de Beires (4 September 1892 – 8 June 1974) was a Portuguese Army officer and an aviation pioneer.

Sarmento de Beires became famous for piloting the first night-time aerial crossing of the Atlantic, in April 1927.

The Argos took off from the Tagus river near the Alverca military airbase, on the March 7, 1927 and arrived in Casablanca, Morocco on the same day.

In Bolama, technical problems prevented the takeoff and the pilot Duvalle sacrificed himself, standing on the ground to ease the weight of the aircraft and allow the continuation of the journey.

Due to engine problems, the mechanic Gouveia needed to intervene twice, saving the flight.
