Fokker S-11-1 Instructor E-14 E-29

The Fokker S-11 Instructor is a single engine two seater propeller aircraft designed and manufactured by the former Dutch aircraft manufacturer Fokker. With replacement of the Tiger Moth in mind, the Lucht Strijd  Krachten ((LSK) Royal Netherlands Air Force) had taken an interest right from the beginning and it ordered 39 examples. In  1950 the first LSK aircraft entered service with the KLu (Royal Netherlands Air Force) and were placed with the Elementary Flying Training (EVO) at Woensdrecht Air Base. From 1968 the EVO operated from Gilze-Rijen Air Base, as Woensdrecht became a “sleeping” base. The S-11 was built under licence in Italy, Israel and Brazil in large numbers. In addition, Fokker developed a version with a nosewheel, the S-12, but the air force showed no interest. September 1973 brought a definitive end to S-11 service with the KLu, which also meant a farewell to the last propeller-driven aircraft!
