de Havilland Aircraft Museum

Many aviation museums show aircraft that were delivered from somewhere at some point. At the de Havilland Aircraft Museum, the most important exhibit stands where it was created. On the grounds of Salisbury Hall near London Colney, north of London, a small team designed the Mosquito from 1939 – and the yellow prototype W4050 returned to exactly this spot in 1959. A museum has grown around it that is devoted consistently to a single manufacturer: de Havilland, from the Moth biplane through the Comet to the BAe 146, which was still developed at Hatfield.

Salisbury Hall: a manor house as a design office

Salisbury Hall is not an airfield and never was one. The present moated manor house dates in its core from the 17th century, and earlier buildings on the site go back to the Middle Ages. Residents in the early 20th century included Lady Randolph Churchill, and in the 1930s the locomotive designer Sir Nigel Gresley – a nice footnote for anyone who likes steam locomotives as well as aircraft.

The place becomes important for aviation in autumn 1939. Shortly after the outbreak of war, the de Havilland Aircraft Company moved the design team for a new, fast multi-role aircraft here from its main plant at Hatfield. The remote country estate offered peace and protection from air raids on the plant. Next to the manor house, a hangar disguised as a barn was built in which the prototype was assembled. In 1947, de Havilland left the site again.

How the museum came about

By the mid-1950s, Salisbury Hall had fallen into disrepair. In 1955, the former major Walter Goldsmith took on the property and learned of its role in Mosquito history. De Havilland had stored the prototype at Hatfield after the war; that it was not scrapped it owes partly to plant employees who kept it for years. Through a fundraising appeal and with de Havilland’s support, the aircraft returned to Salisbury Hall and was given a small hangar.

On May 15, 1959, the museum opened to visitors – with one hall and exactly one exhibit. According to the museum, it was Britain’s first aviation museum. From then on, the collection grew steadily:

To this day, the museum is largely carried by volunteers. Many restorations, including that of TA634, were tackled by the Supporters Society on its own. If you would like to lend a hand yourself, the article on volunteering in aviation museums offers a starting point.

The Mosquito: three “Wooden Wonders” under one roof

The de Havilland DH.98 Mosquito is one of the most remarkable aircraft of the Second World War. Originally conceived as an unarmed, fast reconnaissance aircraft and bomber, it later flew as a fighter-bomber, night fighter, anti-shipping strike aircraft, trainer and target tug. Its fuselage was made of a wooden sandwich construction – hence the nickname “Wooden Wonder.” It was powered by two Merlin engines from Rolls-Royce. According to BAE Systems, a total of 7,781 were built.

The prototype W4050

The star of the house is the prototype with the identity W4050 (constructor’s number E0234), easy to recognize by its yellow paint. On November 25, 1940, it took off at Hatfield for its first flight, with Geoffrey de Havilland Jr. at the controls. This began a career that made the type one of the fastest piston-engine aircraft of its time.

That you can see W4050 in this condition today is the result of a multi-year conservation that was completed in December 2015. The museum deliberately spoke of conservation rather than restoration: the aim was to preserve as much original material as possible – a prototype showing signs of use simply tells more than an aircraft done up like new.

Fighter-bomber and target tug

Besides the prototype, the museum shows two more Mosquitos. TA634, a TT.35, came to Salisbury Hall in 1971 as a gift from the City of Liverpool. Before that, it had appeared in the film “Mosquito Squadron.” Because it initially stood outdoors, preserving it was laborious; the Supporters Society completed the restoration in 1990. The third aircraft is an FB.VI fighter-bomber, which the museum presents as a restored fighter-bomber version.

Three Mosquitos under one roof are rare; other examples in England stand, for instance, in the RAF Museum Hendon, the RAF Museum Cosford and IWM Duxford. If you compare the variants side by side, you can see the differences in nose and armament: the bomber and target-tug variants have a glazed nose, while on the fighter-bomber cannons and machine guns sit in the nose. A stored fuselage of TJ118 and the restored Merlin engine of the night fighter HJ719 round out the theme.

The Comet: the first jet airliner

For airliner fans, the de Havilland DH.106 Comet is the second big reason to visit. The Comet was the world’s first jet airliner; it first flew at Hatfield in 1949 and entered scheduled service with BOAC in the early 1950s. After several accidents in 1954, the early Comets were grounded and intensively investigated – metal fatigue at fuselage openings is considered the main cause. Later versions received, among other things, a reinforced fuselage and rounded windows.

The fuselage F-BGNX

The museum has the fuselage of a Comet 1A with the registration F-BGNX, under which the aircraft once flew for Air France. It still shows the original square passenger windows of the first Comet generation and is considered the last surviving Comet 1 with this window shape. Since the end of 2019, it has stood in the then-new Sir Geoffrey de Havilland Hangar; according to the museum, you can walk through the fuselage.

The Comet collection goes beyond F-BGNX. It includes the nose section of the Comet 1A G-ANAV, the cockpit section of a military Comet C.2(R) with the serial number XK695 and another Comet 2 nose. Together they give a fairly complete picture of early Comet development, even if no complete aircraft with wings is among them. The whole story from triumph to investigation is told in the article De Havilland Comet: the first jet airliner.

From the Moth to the BAe 146: the rest of the collection

The museum’s special appeal lies in its coherence. Almost everything you see comes from de Havilland or was created in its tradition – especially at the Hatfield plant, which later belonged to Hawker Siddeley and British Aerospace, a predecessor of today’s BAE Systems.

Piston-engine classics

The company’s early history is shown by the Tiger Moth G-ANRX, the Hornet Moth G-ADOT and a replica of the DH.88 Comet racing aircraft G-ACSR, among others. Fragments such as the fuselage of a DH.53 Humming Bird and a Queen Bee – a radio-controlled target drone version of the Tiger Moth – round out the picture. A Dragon Rapide with the registration G-AKDW is under restoration. On loan from the Science Museum there is also a Cierva C.24, a rare autogyro from the early 1930s.

Postwar civil aircraft

Of interest to airliner spotters are the smaller civil types of the postwar period:

The Dove was a compact feeder and business aircraft, the Heron its stretched, four-engine sister. With the DH.125, one of the most successful British business jets was created at Hatfield; as the HS 125, BAe 125 and Hawker 800, the design was built for decades. The Trident was the three-engine short-haul jet associated above all with BEA, and the BAe 146 closes the arc into the 1980s.

Military jets and engines

On the military side stand the Vampire FB.6 J-1008 from Swiss service and the two-seat Vampire T.11 XJ772, plus the distinctive Sea Vixen FAW.2 XJ565 with its twin booms. The tail section of a Hornet, several stored Venoms and a Sea Venom under restoration show how de Havilland made the step to the jet aircraft after the Mosquito. A Chipmunk T.10 (WP790) can also be seen as a trainer – the type comes from the Canadian subsidiary de Havilland Canada.

Technology fans should not skip the engine collection: Gipsy piston engines, the early jet engines Goblin and Ghost, the large Gyron, rocket engines such as the Super Sprite and Spectre and a cutaway Merlin tell the house’s propulsion history. Added to this are the fuselage of an Airspeed Horsa cargo glider and a historic LINK flight trainer.

The halls

The museum has grown considerably in recent years. The most important new building is the Sir Geoffrey de Havilland Hangar, which opened in February 2020. Among other things, the Comet fuselage stands here, finally protected from the English weather. It is named after the company founder, who built up the business in the 1920s.

The second new building, opened in 2016, now bears the name of the aviator Amy Johnson. Restoration work goes on continuously at the museum, for example on the Dragon Rapide G-AKDW and a Sea Venom. There are also older exhibition areas, the Comet Café and a shop. By booking, the museum also offers a Mosquito flight simulator with a replica cockpit and surround projection.

Photography at the museum

Salisbury Hall is not a spotting site in the classic sense – nothing takes off or lands here. Photographically, the museum is rewarding nonetheless if you adapt to indoor conditions.

Wide-angle instead of telephoto

In the halls, the aircraft stand close together. Especially with the Mosquitos, which have a wingspan of over 16 meters, there is often not enough distance for an overall view. A wide-angle or standard zoom matters more here than the telephoto lens. With short focal lengths, watch for converging lines and distortion at the edge of the frame – the basics are in the article on wide-angle and standard lenses.

Details tell the story

Instead of always capturing the whole aircraft, details are worthwhile: the yellow skin of the prototype, the glazed nose of TA634, the square windows of the Comet or the twin booms of the Vampire and Sea Vixen. If you want to identify museum aircraft reliably, the article Recognizing vintage aircraft in the sky can help.

Planning your visit

The museum is located at Salisbury Hall, London Colney, Hertfordshire (AL2 1BU), right by the M25 motorway north of London. The easiest way to get there is by car; the museum gives parking information on its website. If you arrive without a car, plan the connection by rail and bus in advance – the location on the city’s edge makes the last leg somewhat more laborious than with museums in central London.

According to the museum, it is open Tuesday to Sunday. In the summer season from March 30 to October 31, hours are 10:30 a.m. to 5 p.m. with last admission at 4 p.m.; in the winter season from November 1 to March 29, 10:30 a.m. to 4 p.m. with last admission at 3 p.m. On Mondays it is open only on bank holidays. Over Christmas 2026, the museum is closed from December 21 to 26 and then open from December 27 to January 3. It is best to check admission prices and special events on the official website shortly before your visit. For a thorough tour, three to four hours is usually enough.

Combining with airports and museums

Because nothing flies at Salisbury Hall, it is worth combining the visit with an active airport. Closest is London Luton Airport north of the museum, a bit farther east London Stansted Airport with plenty of low-cost and freight traffic. Via the M25, London Heathrow is also easy to reach – there you see the long-haul fleet of British Airways, and a proven location is Hatton Cross. All the tips are in the guide Plane spotting at Heathrow.

For a museum trip through southern England, further destinations suggest themselves. IWM Duxford near Cambridge combines a large museum with an active warbird airfield – classics fly there regularly at the Duxford air shows. The Shuttleworth Collection in Old Warden shows flying vintage aircraft, including types from the de Havilland family. The RAF Museum in London Hendon lies in the north of the capital, and the Brooklands Museum tells the story of the competitor Vickers in the southwest.

Conclusion

The de Havilland Aircraft Museum is small compared with Duxford or Hendon – and that is exactly what makes it special. It is the place where the Mosquito was designed, and its prototype now stands a few meters from where it was created. Add two more Mosquitos, the Comet with its square windows and a collection that depicts more than half a century of aircraft building by a single manufacturer.

You won’t see anything fly here. Instead, you get history first-hand, told by volunteers who restored many of the exhibits themselves. Combined with Luton, Stansted or a day at Duxford, it makes a well-rounded trip for anyone who loves British aviation.
