The Breguet 19 T.F. Super Bidon, better known under its nickname of Question Mark, was one of the most important actors of the conquest of the air in the 20th century.
The first flight of the aircraft took place on July 23, 1928 as the third and last Breguet 19 T.R. (for transatlantic) with Hispano engine. Its transformation into a "Super Bidon" came later, during a construction project involving many modifications: increase of the two wingspans and the distance between planes, change of the mature, lengthening of the fuselage, increased fuel capacity.
