1.NetherlandsKLM was founded in 1919, flew its first flight in 1920, and started regular scheduled services in 1922. The Netherlands is the birthplace of Fokker aircraft and KLM mainly used Fokker planes in the early years. Postcard wise KLM is known for the number of Real Photo postcards they produced both for their own airliners and some foreign airlines as well. They became a significant user of DC-2 aircraft in 1934 and added the DC-3 in 1936. I'm listing the aircraft in chronological order by when they were first put into service by KLM. Other airlines from the Netherlands will be listed at the end of the KLM postcards.
