Last Sunday and Monday, Karl and I headed south to Hertfordshire and Surrey, to visit two important aviation museums, each with some very rare exhibits.
Whilst the De Havilland Museum is dedicated mainly to aircraft produced by that famous company, the Brooklands museum is a much larger site, once the location of the Vickers Armstrong factory, which later became Vickers Weybridge site, and was also the 'birthplace' of British motor racing, with part of the World's first purpose-built race track still preserved, and a fantastic collection of racing cars from the 1920's to the present day, which will be covered in Part 2.
But first, I'll start with the DH Museum, and I'm sure Karl will add some pics once he has some time after moving house.

Part 1 - The De Havilland Museum.

This is a relatively small Museum, situated in the grounds of Salisbury Hall, near Hatfield, England, and was, of course, where the DH Mosquito was designed and first built.
Although small, it is very well laid out, and there are lots of interesting, and rare, airframes and artefacts well displayed in the packed hangar and other buildings, with a new hangar currently under construction.
Salisbury hall itself is now a private residence and, although not open to the public, it's frontage can be clearly viewed as one enters and leaves the museum grounds. It's over thirty years since I last had the opportunity to visit here, and there have been many improvements since then, and, at present, it is the only place where three Mosquitos can be seen together, including the prototype, W4050.

So, on to the first set of pics, with the Mosquitos in the main hangar. Due to the construction of the new hangar, the aircraft here are currently crammed in, and photography was slightly difficult.

PIC 1. The prototype Mosquito, W 4050, in its later guise as a test aircraft for the two-stage Merlin engines, when camouflage was added to the upper surfaces of the original overall 'prototype yellow' scheme.
PIC 2. Mosquito B.35. This was converted into a TT35 target tug, and later converted back to bomber configuration for display. From memory, this is one of the aircraft which appeared in the movie '633 Squadron'.
PIC 3. It was only possible to photograph the nose of the now restored FB.VI which, during my last visit, consisted of a bare fuselage and some bits and pieces.
PICS 4 to 6. This is the 6 pdr Molins gun, fitted to the 'TseTse' Mosquito. The breech and ammo feed are huge, and the wing and undercart of the FB.VI in the background give some idea of its size and bulk.
Pics 7 and 8. Rear views of the B.35.

Have many happy memories of visiting both museums. The 2 are among my favourites back in Blighty. One highlight of Brooklands, for me at least, is the short section of 1930s vintage banked concrete racing track that once ran around the perimeter and hosted the British Grand Prix. Always loved the DH Museum, too. A lot of dedicated helpers keep that place alive.
 
Ah, the banked track, near the 'Members Bridge', is yet to come - and with a pic, from Karl, that shows what is probably the smallest, slowest vehicle ever to negotiate that famous, and scary, track !!
 
As Buffnut noted, a lot of dedicated staff and volunteers keep these museums going, and we found the staff at both venues to be very friendly, helpful and knowledgeable, with at least one chap being a pilot himself (flies a Stearman in the UK, and a Cessna floatplane in Canada - and I'm not jealous ... honest ... cough !).
Back to the DH Museum, and the nose section and engine, along with a cockpit view, of the DH Sea Venom.
And a very rare exhibit, the former Air France Comet 1 jet airliner. The interior is stripped on the port side to show the construction, and the flight deck is currently under restoration.
Contrary to popular belief (or perhaps myth), the losses of the early Comets were not caused by the 'square' windows in the cabin breaking (and they're actually almost rectangular, with rounded corners), but by an antenna fairing on top of the fuselage breaking away, and ripping open part of the fuselage skin, causing depressurisation. Bear in mind that this was the first aircraft to have an entirely pressurised cabin and flight deck, as earlier types only had pressurised compartments.
As with many of the aircraft at Salisbury Hall, access is allowed, and free, although some have placards politely requesting that visitors do not sit in the aircraft,

Moving on, and some shots of some of the exhibits in the main hangar, with a section of Airspeed Horsa assault glider, and the detachable nose / cockpit section.
The black and white 'sphere' is a 'Highball 'bouncing bomb', smaller relation to Barnes Wallis's 'Upkeep' dam-busting bomb. Two of these could be carried, in tandem, by a Mosquito.
Under the port wing root of the Mosquito B.35 is a 4,000 lb 'cookie'.
Outside the main hangar is this lump of concrete, often missed by visitors, who probably think it's a garden sculpture. It is, in fact, one of the original moulds for the Mosquito fuselage.

More to follow tomorrow.

Excellent Terry.

Contrary to popular belief (or perhaps myth), the losses of the early Comets were not caused by the 'square' windows in the cabin breaking (and they're actually almost rectangular, with rounded corners), but by an antenna fairing on top of the fuselage breaking away, and ripping open part of the fuselage skin, causing depressurisation.

While that is partially true, it's not entirely, as during testing of G-ALYU in the water tank at Farnborough, one of the windows did fail, the forward escape hatch with a gash 8 feet in length. The ADF window was also a source of failure, but these weren't the cause of the Comet's woes, just the symptoms. Stress failures occur in openings cut out of metal, as you're probably aware, but a number of issues caused the failures. Metal fatigue as a result of rates of pressurisation; the Comet would climb and descend quickly, the fuselage flexing all the while, which resulted in explosive decompression as a result of weakened structure. Skin thickness was also identified as being too thin in certain areas. In subsequent airliners, pressure heights were pushed higher to relieve pressure of the fuelages, too. The industry learned a lot from the Comet disasters.

Although in F-BGNX, this is the exact same window that failed in G-ALYU in the pressure tank at Farnborough.

Forward escape hatch
 
The Mosquito Museum is a great place, but it suffers from that same issue that other semi-private museums do, too much stuff cluttering the display spaces. You can see it surrounding the Mosquitoes.
