| | Hans Peter Hartmann, e-mail, 15.03.2016 06:28 As a little boy I managed to get a seat on a Kooloven on a pleasure flight full of children. It was around 1953 when Alpar organized 10-minutes flights around Berne Airport for a children-club called Fip-Fop-Club (founded by Nestlé to entertain kids). What a treat: My first flight ever! reply | | Noname, e-mail, 31.03.2020 10:24 The F.K.50 was designed to meet a requirement from the Swiss reply | | deaftom, e-mail, 09.03.2011 19:25 Frits Koolhoven was a prolific aircraft designer and designed aircraft for companies not only in the Netherlands (Nationale Vliegtuigindustrie and his own company, N.V. Koolhoven Vliegtuigen), but also for Armstrong Whitworth and BAT in Great Britain and, I think, Desoutter in France. I have records of no less than 45 of his designs being built; probably there were even more than that. His "F.K." design numbers went at least as high as F.K.58. reply | | Mordechai Dessaur, e-mail, 03.03.2009 06:45 The first FK-50 flew in 1935 and was mainly used by the Swiss firm Alpar (till 1962!!!!), 3 built,2xP&W Wasp Junior 303kw(406 hp), first built with single fin & rudder, later with twin vertical surfaces, max. speed 295 km /h, 8 pax.
