An unknown pilot, probably Argentinian, stands beside the S.E.5a as it has its engine run up while in service with the Aviacion Naval, the Argentinian naval arm, in the late 1920s.

The sole Argentinian Navy S.E.5a, AC-21, following its rough landing at Campo Sarmiento on January 24, 1929. Note the Sun of May symbol on the rudder.

Another view of S.E.5a AC-21 having come to grief during its last flight in January 1929. It never flew again.
