Because of the height measuring pole, the photo is assumed to have taken at Felixstowe where Caledonia was subjected to airwhortiness trials at MAEE in the indicated period.

Obsolete aircraft displayed in the Palace of Industry at the British Empire Exhibition, Wembley Park. The sole Type 62 aircraft had a Napier Lion engine and first flew in 1921.

A second aircraft, Type 75, G-EBEV, had the intended Bristol Jupiter engine and served as a freighter. A third, Type 79, to RAF as Bristol Brandon. Postcard.

Entered Imperial Airways service in mid-1939. Opened a Shoreham - Bordeaux - Marseille - Tunis - Malta - Sollum - Alexandria service after the outbreak of war. British postcard.

One of the last photos of the DH.66 prototype. Then five years old, it crashed at Kupang during a proving flight from Britain to Australia in April 1931. This photo must have been taken in the Netherlands East Indies (now Indonesia) as one of the barrels appears to read 'De Bataafsche Petroleum Maatschappij' and the other 'Palembang'. The photo is indeed dated 1931 by the Dutch source. Note retrofitted enclosed cockpit. Photo from: KB - National Library of the Netherlands

'In service on the India route.' This one was the last of eleven DH.66 aircraft built, ordered as a replacement in 1929. She made a route proving flight to Cape Town in December 1931. The later DH.66 airframes featured an enclosed cockpit which was retrofitted to the earlier machines. Postcard.

Cambria left from Foynes on a transatlantic proving flight on 29 July 1937. It looked like Foynes would become an important transatlantic terminal, but WWII killed the flying boat. The Foynes seaplane station closed in 1946, replaced by Shannon airport, not far away. Photo from: National Museum of Denmark

On 30 Nov.1929 it was badly damaged in a forced landing in bad weather near Frankfurt. The five occupants were uninjured and it was repaired and re-entered service but had another accident, at Sarzane, Italy on 13 Feb.1933. It was again repaired but final fate not known.

'Opening of the new Croydon airport [terminal].' The new buildings began operations on 20 January 1928 but were only officially opened on 2 May 1928. The old buildings on Plough Lane had not yet been fully demolished by then. The photo was most probably taken on 21 March when King Amaunalla of Afghanistan made a flight in G-EBOZ and inspected 'two lines of light aeroplanes, including privately owned DH Moths, which had been flown to Croydon.' G-EBOZ was still named City of Wellington on that occasion. It was renamed City of Arundel later on. Photo from: The Henry Ford
