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.

Friedrichshafen FF.29


The Friedrichshafen FF.29 was designed as a light weight biplane on floats. IT was equipped with a Mercedes D.II engine and succeeded the pre war FF-19.

44 Examples were built.
First examples entered operational service in November 1914. It was used for patrols along the coast and also for reconnaissance duties. It was possible to carry a small bomb load.
Noteworthy is the fact that a FF.29 was the first aircraft to be launched from a submarine.
The FF.29A was a version with improved floats and tail.
