During the Open Week at EHSB commemorating the 55th anniversary of the Netherlands air force. A full week open house apparently was too much for the air force. They never attempted a similar setuop again.
In fact this is F-84G K-167 with K-85 on the fin. Whether the fin is wrongly painted or the fin of K-85 was fitted is not known. By 2019 this aircraft was still preserved at Eindhoven, but with its correct identity on the fin.
Built as an F-16A and assigned USAF serial 85-0138 but taken on charge Sep-1987 by the Netherlands AF as J-138, by 1998 converted to F-16AM, in Nov-2010 it became Chilean Air Force 757. It is carrying F-16 Mid-Life Update markings and a currently unidentified badge on the intake. The white thing in the foreground is a display-line marker for the pilots.
