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.

An example of this type was bought early nineties and is used for fast VIP transport. This aircraft was bought on the second hand market and completely overhauled. During the operational use a number of problems occured, so a few years ago the electrical wiring was completely replaced.
This particular Gulfstream IV proved to have been used by Gulfstream for testing purposes and its cabling was modified.
