Tri-engine aircraft were very popular during the interwar period; however, the Fokker F-XII model is slightly less renowned.
Only 14 units were made, of which 11 flew in the colours of the Dutch KLM, two joined Danish DDL's fleet, while the remaining one that of the Swedish Aerotransport. While the latter three were used solely for serving intra-European and domestic routes, KLM employed its machines in years 1931-1935 across the company's lengthiest line to Batavia (today's Jakarta).
The total flying time was over 80 hours (!), but split into 8-10 days. Short service "Twelves" took on-board 16 passengers, but transcontinental ones only six, because of real recliners' dimensions. Our photo depicts the Swedish SE-ABZ Varmland, the longest serving unit of the F-XII class.
