Dayton Wright used the DH-4 as the basis of several post World War I projects when military orders were cancelled. Nothing is known of the Sedan other than this photo was taken in early 1919. The location appears to be Deeds airfield which Dayton Wright used for test flying for aircraft built at its factory in nearby Moraine. Photo from: National Archives at College Park, Maryland

Aircraft under construction at Old Warden to be flown at a later date. Note Bristol Boxkite G-ASPP behind. No fabric has been applied to the Farman to date.

Tandem two-seat aircraft similar to the S-7 which had side-by-side seating. One S-6 built. It became NC98 in April 1927 when the US adopted registrations for all aircraft. Registration cancelled in 1931. Photo from: National Archives at College Park, Maryland

Four S-3 were built for the US Army but it is not known if this was one of them or remained the prototype. Serials 322-325 applied to the army aircraft. They had the distinction of being the first scout aircraft used by the US army. It was two years after European air arms had introduced scouts.

One one S-7 built. Similar to the S-6 but with side-by-side seating instead of tandem seating. Thomas-Morse called it the Sociable Seater. It was sold and used for aerial survey but it does not appeared to have been around when registrations became mandatory. Photo from: National Archives at College Park, Maryland

Believed to be a prototype of the Twin JN although the picture was taken about nine months after the Twin JN appeared in April 1916. The rudder and undercarriage match photos of the prototype and differed considerably from production aircraft. Small numbers built for the US army and navy.

This CM-170 never flew with the Belgian Air Force, but is former French Air Force 208.

Photo taken at SIAI's factory in Sesto Calende. SIAI was exclusively a flying boat manufacturer at the time, the "I" standing for idrovolanti or seaplane in English. The FBA was a French design, with FBA standing for Franco-British Aviation. Louis Schreck was the designer. The H model was built in large numbers in both France and in Italy under licence by SIAI.

Inspired by the Lippisch delta designs from the fourties, this home built delta configured aircraft was constructed in the seventies. Due to no documentation it never got a flying permit. Some taxi tests was done in Zell am Zee in 1990

Ex Slovakia Air Force 8940, ex Czechoslovakia Air Foce 8940. It was hiding between two buildings.

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.

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

Built for inventor Alexander Graham Bell to test his tetrahedral structure. Much simpler triplane configuration compared with the AEA Cygnet unsuccessfully tested in 1909. Attempted test flights with the Oionus on the day of the photo saw three wheels lift off but not all four. Melting ice ended any further attempts to fly it. Photo from: Ken Molson fonds - Ingenium

Flown by J.V. Cavanaugh. The rudder of this Model D is different to the normal rectangular rudder fitted to this type of aircraft. It retains the canard elevators that had been largely dispensed with by 1912. Photo from: Ken Molson fonds - Ingenium

Design commissioned by Boston resident Gardiner Greene Hubbard II and built at Baddeck by Canadian Aerodrome Company. The Hubbard attended the 1910 Montreal Aviation Meet but its owner was unable to coax it into the air because it was underpowered. It was then shipped to Boston where it attended the Harvard-Boston Aero Meet. Again it did not fly. Photo from: Ken Molson fonds - Ingenium

The Baddeck No.2 was built at Baddeck, Nova Scotia, where under the encouragement of inventor and local resident Alexander Graham Bell aviation experimentation flourished. It participated in the Montreal Aviation Meet held in a paddock at Lakeside, now known as Pointe-Claire. The photo shows an apparent forced landing at that meet. The Baddeck No.2 made at least 60 flights before being grounded in November 1910. Canadian Aerodrome was the successor to the Aerial Experiment Association (AEA).

Yes, this is a real aircraft and yes it did fly - eventually. But it required more power than in 1909 and even then it was only in ground effect as the Cygnet III. Soon after the March 1, 1912 hop the tetrahedral cell wing collapsed, ending the project. Baddeck was the centre of Canadian aviation development with famous inventor Alexander Graham Bell a local resident and keen proponent of aviation. The frozen lake provided a large, flat, low friction surface for test flights. Photo from: Ken Molson fonds - Ingenium

This early US airline offered flights from Key West to Havana and from Miami to Bimini - both international destinations which still allowed drinking. Photo from: Florida Keys Public Libraries

This Mi-8 was built in March 1979 and delivered to the Iraqi Army as 204. In 1989 it was sent to Hungary for overhaul at Tököl but placed into storage upon completion due to the sanctions against Iraq. In August 1992 it became property of the Hungarian AF, given the serial 6204 and became based at Szolnok. After a period of storage it acquired the Ukranian registration UR-PLF but is now parked (preserved or operational?) at the M-Air facility in Chocznia without a visible reg.
