I know very little of this picture. By 1980 the aircraft was privately owned, so it must have been taken in the seventies. The background looks like Bern and Alpar is based there. Nevertheless the location needs confirmation. Photo via G.Bouma

First flown in 1944, the SB-2 Pelican (or Pelikan) was the first Pilatus aircraft, designed in cooperation with the ETH technical university. It had six seats, a tricicyle landing gear and a forward-swept wing. The sole example was used by Alpar of Bern until a mishap in 1948. Photo from: ETH-Bibliothek Zürich

The FK.50 eight-passenger airliner was ordered by the general manager of Alpar whom Frits Koolhoven had met in Davos in the spring of 1935. Three examples were built for this airline from Bern, this being the prototype. The second one, HB-AMO, soon crashed during blind-flying training but was replaced by the third, HB-AMA, an FK.50A with double tailfins. The type was well liked and operated Alpar's Bern-Paris-London service as late as 1946. HB-AMI was scrapped in 1947. The FK.50A even survived until 1962 when it crashed in Liberia as EL-ADV.
