Klaas Willem Jonker
(Wilko)
† 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.

Farman MF-40

History

The Farman factory was founded at about 1908. The two brothers Henry and Maurice Farman showed three aircraft, designed by Henry Farman, at several air shows in August 1919.
In 1914 the factory employed about 600 employees.
Due to personal problems both brothers had their own, strictly segregated design bureaus.

The aircraft, designed before World war I by Henry Farman, showed a great resemblance.
All types were of the pusher type with a rotating engine,  a wingspan of the lower wing being half of the wingspan of the upper wing, a open fuselage for the crew and two tail booms..
Main differences were wingspan an engine type.

The Farman F.40 was the first  type both brothers designed together and was released in 1915.  It was a pusher type biplane with a Renault engine rated 130 hp. The fuselage, resting on the lower wing in the designs of Herny Farman, was now positioned just between the upper and lower wing.

Because of the quick developments = the MF-40 proofed to be to vulnerable for operational use and was mainly used as a trainer or handed over to smaller allied countries such as Belgium.
