The serial, 1525, marks this as a RNAS aircraft. Photo from: Library and Archives Canada

The serial is 9233, not N9233 as it appears to be in the photo. N9233 was a post-war Fairey III while the 50 Beardmore-built Nieuport 12s were delivered when the RNAS was still using numerical serials. Obsolete by the time they arrived, Beardmore aircraft were used mainly as trainers. Photo from: Library and Archives Canada

Sold in the US after the war ended. Canadian Aeroplanes was the government-owned former Curtiss factory at 1244 Dufferin Street. It is not clear if there was an airstrip at the factory. The factory occupied six acres and all photos of aircraft there were taken inside the building. Captions on those photos suggest the aircraft left the factory dismantled. The RFC had two training airfields a short distance to the factory. Library and Archives Canada

Experimental fighter. Its poor handling saw it rejected for service. B1484 aircraft is sometimes described as the prototype that crashed on August 17, 1917 but other sources say that aircraft had no serial and B1484 was the first production model. It had three guns, not two as fitted to the prototype. Two others built. Location of the photo is not certain but believed to be Joyce Green (named for a farm) where Vickers had its factory. B1484 also flown from Biggin Hill and Martlesham Heath. Photo from: Library and Archives Canada

American-built Jenny C526, operated by the RFC in Canada, came to grief on the top of a building in Oshawa while on a training flight. The only injury was a woman passerby hit by a falling brick. Her injury was minor. The building has since been demolished. Photo from: Ken Molson fonds - Ingenium

Operated by Curtiss Flying School which had its flying boat school at Hanlan's Point in the Toronto Islands. The site of the school is now within the boundaries Billy Bishop City airport, which was built about 20 years after the school closed. The geographical feature Hanlan's Point was obliterated by landfill used to build up the airport site. Photo from: Ken Molson fonds - Ingenium.

This JF Duck is listed as having crashed in New Jersey on 19 January 1935 with old serial 162, yet here it is three years later at an exhibition - likely not airworthy. The Douglas Sleeper Transport, NC18109 of United Air Lines, was displayed jointly by UAL, American Airlines, Pan Am and TWA. Photo by: Bernard Hoffman / Life

On 23 March 1953, pilot Mira Slovak headed west after taking off for a scheduled flight from Prague to Brno. Most passengers wished to return to Czechoslovakia. The aircraft was also returned, and crashed into the Tatra Mountains on 18 January 1956. Photo by: Ralph Crane / Life

'Arrival of Havana Clipper at Biscayne Bay.' The name of the third S-40 is listed as Southern Clipper. The photographer probably meant 'the Clipper from Havana'. Photo by: Gleason Waite Romer / Miami-Dade Public Library

Photo appears to show NZ3246 in open storage at RNZAF Rukuhia, as Hamilton aerodrome was known then. Hundreds of World War II surplus aircraft were held in open storage there, cockpit canopies open to the weather, pending sale to scrap merchants. This was the fate of NZ3246.

Ed Peterson built his own Bleriot monoplane. The aircraft was not able to fly on the day this photo was taken. Peterson persisted and in 1911 he flew it at Mission Island at the mouth of the Kam River. But the aircraft was underpowered and the flight reached only 50 feet and covered only half a kilometre. Having achieved his aim, Peterson gave up flying for other interests. Photo from: Ken Molson fonds - Ingenium

Aircraft brought to Nelson by steamer by American pilot Walter Edwards (real name Walter Edward Kittel) to fly at the annual Nelson Fruit Fair. He found the fairground a dangerous site with buildings and power lines surrounding it. Nevertheless he flew the Curtiss and thrilled the townspeople who had not seen an aircraft before. Edwards resumed using the name Kittel in his post-aviation business career. He died of heart disease, aged 42, in his home town of Seattle in 1922. The Fairgrounds are no longer existing. After the main fair building burned down in 1935, the site was redeveloped quickly as a theater. Photo from: Ken Molson fonds - Ingenium
