Another very early Ju 52/3m. Used as a seaplane on the Stockholm to Helsinki and Reval (Tallinn) routes in summer and as a landplane on the Malmö - Amsterdam route in winter. Aircraft name on lower nose. Aircraft militarized during WWII. Flown by minor Swedish companies until January 1954, then destroyed by Bromma fire brigade except cockpit which is preserved at Arlanda.

Örnen (eagle), ABA's first DC-3. Orange neutrality paint applied in 1939. To SAS as Arne Viking in 1948. To Transair as SE-BWE. To UN as UN-216. Scrapped for parts after mishap in Kamina, Congo in 1961. Photo from: Life

Stockholm's seaplane airport. The Junkers F13 is SE-AAC which has been preserved not far from here at the Museum of Technology. The little VL Sääski II in the background, OY-ASB, was only registered as such during 1931. Photo from: Tekniska museet

Airframe first flown on 1 December 1936. Also flew as a seaplane. To SX-CDA of Greek airline AME in 1949. Possibly already wet-leased to AME under its Swedish registration from 1947. Destroyed by a storm at Athens - Hassani (Hellenikon) on Christmas Day, 1950. Photo from: Flygvapenmuseum

Scandinavian Air Express titles. The destinations on the sign are Copenhagen, Amsterdam, Rotterdam, Liverpool, London and Paris. Aircraft went to British Airways as G-AERU Juno in January 1937. It ended up with Sabena in Congo. Photo from: Scandinavian Airlines - SAS

Photo described as 'opening of Fornebu' but neutrality markings and blacked-out windows make clear the shot was taken after the outbreak of WWII. The aircraft seems to be painted orange overall. We assume ABA service to Oslo ceased with the German invasion in Norway. Date may be 22 November 1939 when SE-AFA flew the first service between Stockholm and Perth in Scotland, as an alternative to London, with a very experienced crew - Bernt Balchen and Karl Gunnar Lindner.

According to a German source, the Ju 86 was originally designed with fixed landing gear. The narrow-track retractable main gear seems to have worked adequately. Svalan, ex D-AXWZ, was the sole civil Ju 86 delivered to Sweden. It was transferred to the Swedish air force in 1940. Photo by: Asbjørn Barlaup / Nasjonalbiblioteket (Norway)

ABA flew to Zürich via Berlin for a short period in 1939. Photo from: ETH-Bibliothek Zürich

The Northrop Delta was a derivative of the Gamma mailplane, its wider fuselage seating eight passengers. It was not a success as new regulations killed single-engined airliners in the USA in 1934. This example was registered in Sweden on 19 April 1934 and the next morning, it took off for a special Stockholm - Malmö - Amsterdam - Paris flight. Note the Northrop logo on the fin.

Hangar C at Schiphol was used as a night shelter for visiting aircraft. Supposedly named Svealand, the ABA G24 crashed at Tubbergen, Holland on 31 August 1932. Behind the tail of the Farman F.170 Jabiru F-AIDT there appears to be an old Fokker F.III, D-716. There are four more Lufthansa aircraft: three Rohrbach Ro VIII Rolands, D-1712, D-1692 and D-1314, and a Focke-Wulf A 17, D-1388. The Czechoslovak Fokker F.VIIb/3m would appear to be OK-ABT, which was not registered until March 1932; however, the Jabiru is listed as destroyed in October 1931.

SE-BAC was delivered to ABA in September 1937 and this early DC-3, later operated by SAS and Karair, survives in the Finnish Aviation Museum in Vantaa. F-AOTY is a Potez 621. In the background are three KLM DC-2s, PH-ALD, PH-AKN (airborne) and PH-AKS which crashed in October 1938. Photo from: Amsterdam City Archives

International rescue. The Swedish and Finnish Junkers airliners, S-AABG and K-SALG, were involved in the rescue effort following the crash of the airship Italia in 1928. Photo by: Vilhjelm Riksheim / Perspektivet Museum
