Opening of Sola. The German aviation industry was well represented. This Ju 86 was Swissair's HB-IXI, traded in for HB-IXE after a mishap. D-AVEF became NF-SD in the Luftwaffe and flew until March 1945. Interesting details of the Junkers flaps and of the Ju 86's retractable landing gear, said to have been an afterthought. You'll have to fill in the rumble of the diesel engines! Photo by: Asbjørn Barlaup / Nasjonalbiblioteket (Norway)
