Mistakes that remain...
Christiansen did not piloted the Dornier X all the flight. He was "removed" by Dornier so the flight from Bolama ( Africa ) to Brasil and Brasil to New York ( USA ) was done by the German pilot naturalized Brazilian Rudolf Otto Maximilian Cramer von Clausbruch. Von Clausbruch was called back to Brasil due a lack of pilots by Sindicato Condor after Sindicato Condor´s Dornier Wal Olinda crash. The flight from New York to Germany was done by another pilot.
