The last month of peace. Photo almost certainly taken on 2 August 1939 when Lufthansa introduced the Ju 90 on the Berlin - Amsterdam - London route, and some Dutch journalists were given a ride from Schiphol to Croydon and back. On 10 August Mecklenburg violated British airspace restrictions and overflew RAF Manston. By the end of the month regular Lufthansa flights to London had ceased.

This photo was probably taken on 2 August 1939, the day the Ju 90 entered service on the Berlin - Amsterdam - London route. By the end of the month regular Lufthansa flights to London had ceased. If the big Ju 90 continued on the Amsterdam service at all, the photo cannot have been taken much later as the departing Fokker C.X does not wear the wartime orange triangle insignia. The following winter D-ASND was commandeered as BG-GX. Later coded J4-HH, it was destroyed in 1943. Photo from: Nationaal Archief (Netherlands)

Quite a good snapshot of a Ju 90 landing in Oslo, allegedly taken on the first day of the German invasion in Norway, 'Weser Day'. This was Lufthansa's D-ADFJ Baden. Photo from: Arkivverket (Norway)
