While in Berlin, Ole Fahlin visited the Johannisthal Air Field where he took flying lessons from Hans Riesler, an old army pilot.
When he returned home Fahlin eventually flew for the Swedish Royal Air Service as a pilot.
[7] One of his customers was Rudy Kling, an airplane racer, whose Folkerts Special won the Thompson Trophy in Cleveland, Ohio, using one of Fahlin's propeller designs.
[6] As Fahlin's fame increased, Russell B. Nicholas, co-owner of the Nicholas-Beazley Airplane Company, invited him to use his manufacturing facilities in Marshall, Missouri, for free.
[13][14] After the dissolution of the Nicholas-Beazley Airplane Company, the Columbia Chamber of Commerce offered Fahlin factory space in Columbia, Missouri, and Fahlin started taking orders directly from the Federal government during World War II while Air Associates distributed his propellers nationwide.
On January 31, 1992, a memorial service was held at Morgan Hill, California, during which a "missing man flyby" was performed by 10 vintage airplanes flown by his friends.
[2] Fahlin's propeller workshop survives as a working exhibit at the Wings of History museum in San Martin, California.
