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.19


In 1913 the German Navy was looking for a seaworthy seaplane and demanded several manufacturers to develop such an aircraft.

The required seaworthiness implied a structurally strong aircraft, while at the same time wish for a good performance required a rather light plane. Flugzeugbau Friedrichshafen GmbH (FF) developed the Friedrichshafen FF 19, which fulfilled the wishes of the German navy.
