The prototype of the Fokker G.I, a two-seat fighter powered by Hispano-Suiza 14 engines and first flown from Eindhoven - Welschap on 16 March 1937. At the insistence of the Dutch army air force the design was completely reworked as a three-seat multirole aircraft. This was rather counter-productive since the resulting G.I/Mercury served as a two-seat fighter. A batch of the smaller variant with R-1535 Twin Wasp Junior engines was ordered by the Spanish Republicans, but eventually taken over by the Dutch government. The G.I/Wasp aircraft were not yet operational on 10 May 1940 and saw little action during the German invasion of Holland. Photo from: San Diego Air & Space Museum
