Roger Druine built his first aircraft in 1938 at the age of 17, and built a single-seat cabin monoplane, the Aigle, in 1948. His 1950 single-seat D.31 Turbulent was produced in small number by Rollason Aircraft & Engines and Stark Flugzeugbau, and remains available in plans form for home construction. Rollason also built the 1954 two-seat D.60 Condor (plans available). Also remaining available in plans form is D.5 Turbi two-seater, first flown 1951, as a development of Turbulent.
Aircraft
Druiff-Neate Cycloplane

Built by Messrs. C.G. Spencer & Co. of Highbury, N London in 1909, the machine was pedal powered driving a 4ft pusher propeller, although the fitting of a motor was contemplated
Driggs Skylark

The unique Driggs Skylark N11301 c.n 3016 was built in May 1931.
An enclosed tandem two-seater powered by a 95 hp Cirrus engine, modifications to the tail and canopy addition were carried out in May 1942.

Driggs Dart
The 1926 Driggs Dart I was tested by the Army as 26-205.
A variation of the Driggs Dart I was built as the McRae Super Dart.
Driggs-Johnson DJ-1 Bumblebee

The original Driggs-Johnson DJ-1 of 1925 was powered with a 28-hp converted Henderson motorcycle engine. The few production Darts used slightly more power. This is one that the Army bought to test variable-camber wings; low cost and simple construction made it easy to try different arrangements.
Driggs Aircraft Corp
USA
Founded at Lansing, Michigan in 1927 by Ivan H. Driggs, who designed and built his first aircraft in 1915. Later worked as engineer for Dayton-Wright. In 1924, in conjunction with Johnson Airplane and Supply Company, built two Driggs-Johnson DJ-1 Bumblebee racers, followed by a second version in 1925. Developed Dart Model 1 for Air Corps research on high-lift wings in 1926. Driggs products included Dart II and Skylark III. Driggs left to work for Luscombe on the 1934 Phantom I, and Driggs design rights went to Phillips Aviation in 1938.
Drewet 1909 glider

Oliver H. Drewet (or Drewett, but definitely not Drewer) returned to Asansol, India to work as an engineer. It was there that he built his glider, based on a model that he had built before moving to India. A test flight, claimed to be the first in India, was made on 1 March 1909, down an inclined railway, on top of a truck. After 100 yards the machine left the truck with Drewet on board, and flew a distance of 20 yards before crashing.
Dream Wings Valkyrie
The Valkyrie was a sleek, speedy looking airplane on a computer screen. Dozens of DreamWings depositors made their decision to buy a plane while they were sitting at the controls of the prototype, a happy grin on their face. They had found the perfect plane.
One thing led to another–dreams were crushed, careers were ruined, no planes were ever delivered and in 2001 DreamWings ceased operations forever. When DreamWings closed its doors, it left 145 customers behind – customers who lost nearly $1.5 million in deposit money.
Dream Wings LLC
DreamWings, LLC went out of business in 2001
