Apart from several excellent demoteams , such as The Turkish Stars , equipped with former Dutch Northrop-Canadair NF-5A/B’s , the Open Days at Volkel Air Base , the Netherlands in June 2007 , featured some interesting Warbird-participants , including two Hawker Hunters from Sweden (ex Swiss Air Force). Special guests on the Static Show came from Poland and – also not very common – was the presence of a U.S.Navy Lockheed Orion.
In 1989 the Swiss celebrated the 75th anniversary of their Air Force and 25 years of demo-flying with La Patrouille de Suisse. The festivities took place at Sion Aerodrome in Kanton Wallis on June 23rd to 25th including an interesting international air show with both warbirds , civil aircraft and operational military aircraft participating. Hans – while on vacation- travelled all the way by car across the Alps to be present on the 23rd and 24th of June.
