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.

Vickers Viking Mk IV

History

In December 1918 Vickers started an investigation for a suitable hull shape for an amfibie. In 1919 Vickers released the Viking I, a five-person pusher aircraft with a water-cooled Rolls Royce Falcon.

This aircraft, registered as G-AEOV, crashed in December 1919 at Rouen, while it was en route to Paris.

The second prototype, Viking II, registration G-EASC had a enlarged wingspan and a Rolls Royce Eagle VIII of 360 hp.

The Vickers Type 54 Viking IV had an enlarged fuselage and a number of improvements and was usually equipped with a Napier Lion engine.

The Viking V was a further development and was built for the RAF.

The Viking was further developed and resulted in the Fulture I, with a revised wing and a Napier Lion engine of 450 horsepower.
