Cees,
As I think we need to preserve Dutch history here, I roughly translated the articles about de Mok and de Vlijt from the web-site from "Luchtvaart & Oorlogmuseum Texel" (Aviation and War museum Texel).
And for Schellingwoude I used an article of the "Stelling van Amsterdam" (Fortress Amsterdam).
Feel free to use them, as I have written them for that specific purpose!
And here the story about
de Vlijt
In 1937, the Texel Airport De Vlijt was officially opened. This was mainly due to the management of the KLM, which saw Texel as a nice expansion of the domestic air operations.Texel was increasingly visited by tourists and a flight from Schiphol Airport took about 30 minutes, while it took about half a day by road, train, bus, and boat.
The location was chosen on land which originally belonged to a farm called de Vlijt. The farm itself not longer existed, as it burned down in 1932. In 1933 the municipality bought the land and began the construction. It was an almost square area of approximately 600 by 600 meters. At the Postweg a wooden station building was built which included an area for the handling of passengers and a waiting room, where the waiting people could enjoy coffee or something to eat.
In the summer there were usually several daily flights between Schiphol and Texel. Especially at the weekend, there were many passengers. During winter flights were less frequent.
Just before the Second World War the airport received an other destination when it was taken over by the Aviation Section of the Army (LVA). Until well into the thirties the LVA was almost exclusively active at Soesterberg, but this airfield was located outside the "Fortress Holland" and therefore not very useful in a conflict with Germany. Moreover, the LVA were very vulnerable when all military aircraft were based on one single airflied. When the political tensions increased, the LVA decided to construct several military airfields in the west of the country. Because there was a civil airfield on the island Texel already the LVA decided to use this as well. In 1939 a large hangar for storage and maintenance was built. No operational units have ever been stationed on de Vlijt, but the advanced fighter training and training on multi-engine aircraft were located at the airfield.
In May 1940, most aircraft were moved outside the airport to avoid to shelling by the Germans. This wasn’t very successful, as nearly half of the aircraft were destroyed in the first attack. Some obsolete fighter planes (Fokker D.XVII) from the fighter school were transferred to Amsterdam. However these aircraft didn’t play any role in the activities during May 1940.
Soon after the capitulation, the Germans started to use the airfield, but only for short period. In 1941 were fighters stationed at the airfield and the field was still expanded with paved runways. Meanwhile the war situation changed and it was barely finished or it was already destroyed by the Germans.
After the war the Dutch found the airfield completely destroyed. As there wasn’t an immediate need for an airfield, it took until 1953 for the field could be reopened.
The airfield has since been modernised several times and is a landmark on Texel for more than 70 years already.
