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.

Douglas C-54 Skymaster


Douglas developed the DC-4 in response to requests from Eastern and United Airlines, after the failed DC-4E, which proved too complicated and uneconomical.

Before the type entered production World War Two broke out and all contracts were taken over by the USAF, designating the aircraft as C-54; US Navy gave it the designation R5D.

The first C-54 made ​​its first flight on 14 February 1942. 1163 Examples were built between 1942 and 1946. After the war a further 79 DC-4s were built.

After the war the type was developed into the larger DC-6 and DC-7.



At  this website you may find an overview of DC-4 and C-54 variants.
