The Koolhoven F.K.40 was a small airliner built in the Netherlands in 1928 for KLM Royal Dutch Airlines. It was a conventional high-wing cantilever monoplane powered by a single engine in the nose. The fuselage was made of welded steel tube construction with a wooden wing skinned in plywood and held in place by four bolts to facilitate removal. The cabin was spacious for an aircraft of its size, and was intended to be readily reconfigured for passengers, mail, or freight. Although up to six seats could be fitted, the only F.K.40 built flew with four.
This aircraft, registered PH-AES and nicknamed Piet Haas ("Peter Hare"), was operated by KLM until it was sold into private hands in 1936. Shortly thereafter, it was sold to the Spanish Republican Air Force, and was operated as an air ambulance during the Spanish Civil War.

The Fokker F.XVIII was an airliner produced in the Netherlands in the early 1930s, essentially a scaled-up version of the Fokker F.XII intended for long-distance flights. Like its predecessor, it was a conventional high-wing cantilever monoplane with fixed tailwheel undercarriage. Its cabin could seat 12 passengers, or four-to-six on seats convertible to sleeping berths. Only five were built, all for KLM, and registered as PH-AIO, 'AIP, 'AIQ, 'AIR and 'AIS, all of which were named after birds. Used by KLM on its Amsterdam-Batavia route, the F.XVIII became celebrated in the Netherlands due to two especially noteworthy flights. In December 1933, one aircraft was used to make a special Christmas mail flight to Batavia, completing the round trip in a flight time of 73 hours 34 minutes. The following Christmas, another F.XVIII made a similar flight to Curaçao in 55 hours 58 minutes after having been specially re-engined for the journey.
The Koolhoven F.K.30 Toerist was a small sport aircraft built in the Netherlands in 1927, intended for use by aeroclubs. The fuselage carried the pilot and one passenger in tandem in a bathtub-like open cockpit. The cantilever parasol wing was mounted above and behind them, with the main wheels of the fixed undercarriage directly below the wing, at the sides of the fuselage. The engine, driving a pusher propeller, was mounted on the aircraft centerline at the aft portion of the wing. The conventional empennage was carried on a boom extending below the propeller arc. The wing, including engine, was designed so that it could be pivoted 90° while on the ground, allowing the aircraft to be stored and transported more easily.
