04/30/2008. Remarks by Walter van Tilborg: "The Vésin 01 (later F-PZTH) was a homebuilt aircraft that was exclusively built for personal use by Roger Vésin. Emphasis was on the simplest possible and therefore the rear fuselage was left uncovered. Carrying the test registration F-WZTH, the aircraft first flew on July 20, 1984 and had a modified 55 hp VW1500 engine. The aircraft received its CofA on September 19, 1984 and was reregistered F-PZTH. Only two years after the first flight the registration expired in July 1986, however, December 17, 1998, ownership of the one-of-a-kind single-seater was transferred to Paul Sibert."
