In Memoriam

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.

In service with LVA and NEIAF

 In service with NEIAF

The NEIAF ordered six examples in 1939. These were delivered early 1940 at Andir and serialled BJ-001 til BJ-006. The three bombing groups received each one aircraft. One went to the flying school plus two were kept as spare.
In February 1941 it was decided to use the Jungmanns for the training of fighter pilots.
Most aircraft were lost due to accidents and the Japanese attacks.

In 1938 the so called NILF, Nederlands-Indisch Luchtvaart Fonds (Netherlands East Indies Aviation Fund) was raised. This fund was to be used for the training of civil pilots and also for the acquisition of military airmen.
Siz Jungmanns were bought, which were delivered in June 1939. These aircraft all received civil serials. Just before the war there were plans to claim these aircraft for the military, but this never was never realized.

 In service with LVA.

In 1937 the LVA decided to buy one Bu-131 Jungmann for the training of fighter-pilots. Before a pilot was allowed to fly on e.g. the Fokker D.XXI, he was supposed to have flown several hours of aerobatics training on the Bu-131.
The aircraft survived the bombing of De Vlijt on Texel, where the training unit was located and was moved to Germany and used by the Luftwaffe.
