Dutch Modelling and Aviation

In Memoriam

Klaas Willem Jonker
(Wilko)
† April 30, 2018

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