De Havilland Aircraft Company

Designing and producing iconic commercial and military aircraft since 1920.

De Havilland Aircraft Company

The De Havilland Aircraft Company was formed in Hendon by aircraft designer and pioneer Geoffrey de Havilland on 25th September 1920. Space restriction meant however that it moved almost immediately to Stag Lane Aerodrome, Edgeware. 
 
Financial support to start the company (£10,000) came from de Havilland's former employer George Holt Thomas, founder and chairman of The Aircraft Manufacturing Company (Airco) for whom Geoffery had worked after leaving the Royal Aircraft Establishment.
 

Despite a few early successful single and two-seat military biplane designs, de Havilland soon became frustrated with the Air Ministry's technical and procurement procedures during and after World War 1 and so he decided that the new company should concentrate on the fast emerging commercial and private aircraft market. 

Initially, the new company struggled through a lack of investment and they made little impact.  In 1921 however, they were approached by successful businessman Alan Butler, who wanted them to build him a new DH37 aircraft. Before long de Havilland and Butler became firm friends and in fact Butler was so impressed by the men that built his new aeroplane that he asked Geoffrey if they (the company) 'could do with some extra investment?'

Butler invested heavily in the company and helped fund the purchase of Stag Lane, becoming Company Chairman in 1924.  This allowed de Havilland to concentrate on his design whilst Butler ran the business, developing the sales, marketing and production resources.

Often referred to as ‘The DH Enterprise’, the company quickly expanded its engine and propeller production, becoming a major provider to a network of aircraft producers, as well as establishing new manufacturing facilities in both Canada and Australia in the late 1920’s.  

In 1925, the company designed and begun production of the very successful Moth series of light aircraft, a product which was to bring financial stability and success and lead to mumerous developments of the type.

By 1930, The De Havilland Aircraft Company Limited had established Hatfield as its main manufacturing facility, alongside the newly constructed A1 Trunk Road which provided quick and easy access the North as well as London.   Hatfield was a fast growing suburban town which provided and abundance of young, enthusiastic engineers and comfortable, quality housing.

Other factories also supported DH in its war effort, most notably at Leavesden and at Witney in Oxfordshire.

A number of iconic aircraft followed such as the DH Dragon and DH Dragon Rapide before World War II saw a return to military types.  

Despite being considered 'too radical' for the Ministry (who wanted a heavily armed, multi-role aircraft, De Havilland persevered in secrecy at nearby Salisbury Hall and what emerged proved to be one of the fastest and most successful fighter bombers of the era - The De Havilland Mosquito with its high-performance well-suited to an unarmed, high-altitude reconnaissance role and over 7,780 aircraft took to the skies. 

During 1940, the company also expanded further with the acquisition of Airspeed Limited (see separate page) which operated at Portsmouth on the south-coast.  Producing aircraft such as the Oxford, Horsa Glider, Ambassador and Consul, Airspeed initially operated with its own product identity.  However, by 1951 it had merged fully with The De Havilland Aircraft Company Limited and was completing production Vampire Trainers for the military.

Over the years De Havilland, the company and de Havilland, the family faced many set backs. 

In 1943, the founder's 2nd eldest son John was killed in a freak mid-air collision in a Mosquito over St Albans whilst in 1946, eldest son Geoffrey de Havilland Junior lost his life whilst carrying out high-speed trials in the DH108 Swallow, a tailless swept-wing aircraft.

Better times followed for a short period when company Company Test Pilot John Derry is believed to have been the first British pilot to exceed the sound barrier in the DH108 in 1948.  

Danger nevertheless was always evident in the life of any test pilot and Derry himself, along with observer Tony Richards, were to tragically crash at Farnborough Air Show on 6th Spetember 1952 whilst displaying a DH110 Sea Vixen.

The company then suffered its biggest tragedy and set back with an aircraft considered to be 'one of the greatest technological advances of the age'.  

The DH106 Comet, the worlds’ first pressurised jet airliner, suffered a series of disasters between October 1952 and April 1954.  With their most significant aircraft grounded for 4 years it allowed the US Boeing Company to capture the valuable Trans-Atlantic market and secure airline confidence worldwide.

Metal fatigue, a new problem for aircraft construction, was found to be the cause and although Comet returned to service in 1958, the impetus had been lost.

The re-organisation of the aircraft industry at the end of the 1950's saw the De Havilland name survive although in 1963 it was renamed De Havilland Division of Hawker-Siddeley Aviation.  

It continued to produce many of its innovative designs such as the three-engine DH121 Trident and the DH125 Jet Dragon (later known as the HS125 / BAe125).  

Innovation continued under British Aerospace well into the 1990's with major involvement in the A300 programme (HBN100) and HS / BAe146, one of the most successful of the European 'Feeder-liners'.

Hatfield was finally closed its doors in 1993 and although many mourn its loss, the site today employs more people than it did during it's heyday of aircraft making.
