    The Davis series of parasol wing monoplanes was built by former WWI pilotWalter C. Davis and the Davis Aircraft Corporation of Richmond, Indiana from 1929 to 1930. Power plants varied from the 60 or 85 hp LeBlond, through the 100 hp Kinner K-5, the 90 hp Lambert, to the 145 hp Warner Super Scarab model that is the subject of this Oshkosh 1988 photo. The Davis won Approved Type Certificate #256 on 8 November 1929, with the Warner version licensed under Group 2 Approval #394 on 21 December 1931....

    Designed to replace the Wright R-3350 Turbo-Compound powered Canadair CP-107 Argus (remember the May 2003 Mystery Plane?), which had replaced the wartime Avro Lancaster 10, the Lockheed CP-140 Aurora was ordered in July 1976. Wearing serials 140101 to 140118, the Aurora combined elements of the P-3C airframe with S-3A Viking electronics and search gear. With a crew of 11, the CP-140 was powered by four 4910 hp Allison T-56 turboprops. It is fitted out to handle antisubmarine, pollution patrol, s...

    Known as the Bird, Brunner-Winkle Bird, and the Perth-Amboy Bird, this 1929 gem has a lot of history behind it. Luminaries such as Wiley Post, Lee Gehlbach, Clarence Chamberlain, and Milo Burcham all had Birds. The best known owner of a Bird Model BK was Charles Lindbergh who purchased one for $3500 in the fall of 1930 for his wife Anne. It was in NC727Y that she earned her pilot's license, passing her flight test on 29 May 1931. NC727Y still flies, now based in Maryland. Produced under Approved...

    The de Havilland DH 114 Heron, which first flew at Hatfield on 10 May 1950, proved adaptable to stretching and engine changes. Initially powered by four de Havilland Gipsy Queens of 250 to 340 hp, it was later rebuilt with 260 and 340 hp Lycomings. The ultimate modification came in 1969 when Saunders Aircraft of Gimli, Manitoba, reconfigured a Heron Mk. II with a lengthened fuselage, a reengineered wing, and a pair of 715 hp P & W PT -6A turboprops. The fuselage stretch was eight feet six...

    In this day of Predators, Reapers, Global Hawks, and other unmanned aerial vehicles, we forget that aircraft similar in concept have been trialed over the whole course of aviation's century plus evolution. The Boeing YQM-94A is one example. Ordered in 1971 by the U.S. Air Force Aeronautical System Division for high altitude, long RANGE unmanned recon, the YQM-94A and the Ryan YQM-98A, were meant to launch and recover from a fixed runway. Two prototypes of each were ordered. The YQM-94A was...

    The famous Italian aircraft manufacturer Piaggio has existed in three forms. Begun in 1915 at Genoa by industrialist Rinaldo Piaggio, it built parts for Caproni bombers and Macchi flying boats during World War I. Then it specialized in multi-engined aircraft until the armistice in 1943. Re-formed in 1946, Piaggio built trainers, including the P-148 and P-149, for military use. It was restructured again in 1964. Derived from the two seat P-148 tail dragger that first flew in 1951, the...

    The American Helicopter Company was formed in 1947 and produced a small series of pulse jet rotor helicopters beginning with the A-5 "Top Sergeant" in January 1949. This was followed in 1950 by the A-6 "Buck Private." Neither design made it beyond the prototype stage. In 1951 the Army Transportation Corps joined the Air Force in calling for a one man, lightweight helicopter that could be airlifted and used for observation or rescue. In June 1951 a contract was awarded to the American Helicopter...

  • Mystery Airplane: February 2015

    Tom Lymburn, Minnesota Flyer|Feb 1, 2015

    This month's winner Dave Gunderson of Mora wrote, "This little beauty is a Hannaford Bee-model D-1, completed in 1981 by homebuilder John Bright." Joe Connell of Stewartville wasn't fooled either, "I have a Kitfox and used to share a hangar at the Rochester Airport with John Hanson who built a Parakeet." Barry Taylor of Ottumwa, Iowa, called it, "One of my favorite airplanes." Graydon Carlson found the answer in a 1955-1956 issue of Air Progress magazine! Did you note the two different spellings...

    In the years before the Second World War, air racing was the catalyst for improvements in engines, fuels, lubricants, streamlining, and structure. Part of that development encompassed the famous Menasco powered racers of the 1930s. An air cooled, inverted, four or six cylinder inline engine, ranging from the 90 hp Pirate to the souped up 315 hp Buccaneer, they powered racers built by Bennie Howard, Clayton Folkerts, Lawrence Brown, Art Chester, and Keith Rider. Herschel Smith in A History of...

    Praised by Lady Mary Heath, Britain's "Lady Lindy" in a February 1929 issue of Aviation magazine for its "ease of handling and balance of the controls," the Aristocrat was a product of General Airplanes Corporation of Buffalo, NY. Powered by a 110 hp Warner Scarab seven cylinder radial, it appeared at the 1929 Cleveland Air Show. Eight were purchased by the General Tire and Rubber Company for its 50,000 mile, four month US tour in late 1929 and one, registered X7511, was donated to polar...

    Before the end of WWII, Trans-Canada Air Lines foresaw the need for a domestically produced airliner. After considering the Douglas and Lockheed products, the decision was made to adapt the DC-4 with 1760 hp Rolls Royce Merlin 620 engines and a pressurized fuselage. The RCAF also expressed interest, but without the pressure cabin. After the war, Canadair brought C-54 tooling and components from Douglas's Chicago plant. Initial DC-4M and C-54GM production used many Douglas built parts. The...

    Frank Piasecki founded PV Engineering in 1941. His experimental PV-2 helicopter appeared in April 1943, followed by NACA awarding him Helicopter Pilot Certificate No. 1. The H-21 (the May 2011 Mystery Plane) was followed by the PV-14, which led to the Navy's HUP "Retriever" and the Army's H-25 "Army Mule." Powered by a 550 hp R-975 radial engine, the HUP had a maximum speed of 108 mph and a range of 360 miles. Its useful load with two pilots, was 1650 pounds, four to seven passengers or three...

    1946 Dart GC|Mar 1, 2014

    "No other light airplane combines all the features that aviation-minded enthusiasts demand," reads a 1947 advertisement for the Applegate & Weyant version of Al Mooney's classic Dart. Powered by a 100 hp Continental flat six, the Dart GC (C for Continental) was a worthy successor to the earlier Dart G (90 hp Lambert), Dart GK (90 hp Ken Royce), or Dart GW (90 hp Warner Scarab Junior) radial engined models produced by Lambert, Culver and Dart. Ten Dart GC's, licensed under Approved Type Certifica...

    In 1933, Professor Heinrich Focke resigned as Technical Director of Focke-Wulf to purse his interest in rotary winged aircraft. Beginning by license building Don Juan de la Cierva's C.19 autogyro, he worked with aerobatic pilot Gerd Achgelis toward perfecting a practical helicopter. His Fa-223 Drache was one of the few helicopters, along with the Flettner Fl-282 Kolibri and the Sikorski R-4, to see WWII service. In early 1942, the Kriegsmarine asked Focke-Achgelis to design a gyro kite to be...

    Tom Lymburn, Minnesota Flyer|Dec 1, 2013

    The design team of Artyom Mikoyan and Mikhail Guryevich was formed in December 1939 to produce fighters for the Red Air Force. The wartime MiG-3 was fast, but a handful to fly. Post war, the team collaborated on the first Soviet jet, the MiG-9, and followed this with the Korean War MiG-15 and the Viet Nam War MiG-17 and MiG-21. Guryevich retired in 1964 and Mikoyan died in 1970. Designed to replace the MiG-21, MiG-23 and Su-17 with the Soviet Air Forces' Frontal Aviation, the prototype MiG-29...

    Loening OA-1A Grover C. Loening, a 1911 graduate of Columbia University, worked with Orville Wright and the Army Signal Corps before forming Loening Aeronautical Engineering in 1917. He was the first to have a degree in Aeronautical Engineering. First appearing in 1923 as the COA-1, his OA-1 observation amphibian was powered by a 425 hp Liberty. The Army ordered 45 between 1924 and 1928, primarily for use in Hawaii and the Philippines. Fifteen were OA-1A models costing $21,000 each. The landing...

    Former RAF Flight Lieutenant Nicholas Comper formed the Comper Aircraft Company at Hooten Park in 1929 to build the Swift. Its prototype, G-AARX, first flew on 16 April 1930, powered by a 35 hp ABC Scorpion engine. Forty-one Swifts were manufactured and powered by Salmson and Pobjoy radials and de Havilland Gipsy III inlines. With an empty weight of just over 500 pounds and wing span of 24 feet, the Swift proved a natural for air racing. Even the Prince of Wales, later King Edward VIII, owned...

    Tom Lymburn, Minnesota Flyer|Sep 1, 2013

    Wyoming rancher Reuel T. Call and his brothers Ivan and Spencer developed their Call-Air series of light fixed gear wood, steel tube and fabric low-wing strut braced monoplanes for high altitude operations from rough fields. The Model A was ready for production in 1940, but due to the war in Europe, production had to wait until after November 1944 when prohibitions against manufacture of civilian aircraft were lifted. The Call-Air A series was manufactured under Approved Type Certificate #758...
