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.

Gotha WD-11


The Gotha WD.11 (WD = Wasser Doppeldecker) was designed as a torpedo-bomber.

In fact it was a development of the Gotha WD.7, but it was much larger and had more powerful engines. The pilot and the observer/gunner sat in a small fuselage in open cockpits. The undercarriage consisted of two floats.

Twelve examples were built.
