In 2001, Leeuwarden AB, was the host for the annual Klu Open Days. 6 and 7 July the Royal Netherlands Air Force showed its air power. Highlights this year were two A-4s from the Singapore Air Force, on training in Southern France. As the Netherlands were looking for a F-16 replacement, Italy brought a Eurofighter EF-2000 prototype and France a Dassault factory Rafale. But also some more classic fighters like the Romanian Lancer B (MiG-21) and Germany with the, former East German, MiG-29.
Aprt from the earlier mentioned, a nice variety of aircraft. The Swedish Air Force brought the JA37 and the JAS39. The Italian Air Force also brought two AMX light attack aircraft, one painted a a special c/s. The Royal Air Force brought the Tornado F3 and two Jaguars, which were also shown by the French Air Force.
