In Memoriam

Klaas Willem Jonker
† April 30, 2018

On Monday 30 April 2018, Wilko Jonker died after a long illness at the age of 58. He leaves behind a wife and two children. The Dutch military aviation and plastic modeling were his hobby and on this website he shared all the knowledge he has collected over the years. His hobby has been able to distract him from the persistent disease in his body until the last week of his life. The contacts with other hobbyists were a major support for him.

This website will be maintained by different people for as long as possible, so that other enthusiasts can continue to benefit from extensive content.


The Albatros C.X was basically an enlarged version of the Albatros C.VII and designed for the new Mercedes D.IVa engine of 260 hp, which became available during 1917.
The radiator was mounted in the wing and the aircraft was equipped with a number of other, at that time modern features such as an oxygen supply and radio equipment.
