De Havilland D.H.90 Dragonfly

The external similarity between the de Havilland D.H.90 Dragonfly and the D.H.89 Dragon Rapide belied its very different internal structure, the earlier design's spruce and plywood box fuselage being replaced by a pre-formed plywood monocoque shell strengthened with spruce stringers. The lower wing centresection was strengthened, making possible deletion of the nacelle/wing root bracing struts and inner bay rigging wires, and so providing easy access to the cabin, with its accommodation for a pilot and four passengers. Powered by two de Havilland Gipsy Major engines, the prototype made its first flight at Hatfield on 12 August 1935 and the first D.H.90A production aircraft, with Gipsy Major II engines, flew in February 1936. Production totalled 66 Dragonfiies, the type being popular initially with the prominent private owners of the time, both in the UK and abroad, but most were used eventually for commercial purposes. Military purchasers included Canada, Denmark and Sweden.

I had my first flight in a Dragonfly registered CF-BFF on Fairchild floats. It operated out of Rouyn-Noranda for Gold Belt Air Service after purchased from de-Havilland Canada. The flight was arranged by the Canadian Air Cadets of which I was a member. Imagine my surprise 6 years later when I was employed by de-Havilland to see CF-BFF on floats gracing many office walls at the plant. Like all de-Havilland passenger designs it was an attractive looking aircraft with nice lines for a twin-engined bi-plane. Some considered it to be the first of a line what was to become executive and personal type of aircraft. A pilot and four passengers plus baggage in very comfortable accommodations. Sadly,a number of years later during a flight CF-BFF was a victim of icing
and crashed and burned with the remains still in the bush when last mentioned in news.

Chris,

My father and I used to fly the aircraft at Manchester(Ringway as it was known then). It was not a Dragonfly, but a DH-89A Dragon Rapide, owned by Airviews Ltd. of Manchester.
The Rapide had 12 seats, the Dragonfly only carried 4 passengers.
