G-AANLGeoffrey de Havilland’s line of biplane sports/training aircraft, which culminated in the DH82 Tiger Moth, began with the first flight of the DH.60 Moth prototype, at the hands of De Havilland himself, in February 1925. That aircraft, G-EBKT, was powered by a rather unusual engine, built by ADC Aircraft – the Cirrus. This consisted, essentially, of one half of a surplus WW1 Renault V-8 engine, and was, therefore, incredibly cheap. The Moth quickly established itself as the prefered equipment for flying schools and aero clubs everywhere. The Moth was so ubiquitous that soon any light aircraft was refered to as a ‘Moth’.

By 1927, De Havilland had a problem; the huge ‘pile’ of WW1 Renault engines had almost run out, and a new engine for the Moth line was needed. In conjunction with Major Frank Halford, a four cylinder, 100hp engine was designed and built for the DH60; the DeH Gipsy I.

The aircraft you can see is a DH60M Moth, built in 1929. Powered by a DeH Gipsy II of 120hp, it represents the state-of-the-art in light aeroplane design for this period. Several significant changes had been made to the original DH60, including the use of a metal tube primary structure for the fuselage, as opposed to wood (hence the ‘M’ for ‘Metal Moth’). If you look closely, you can still see that De Havilland has retained his ‘differential ailerons’ on the lower wing only, and the wings and tail are in the traditional ‘any colour so long as it is silver’  factory finish (the aero club, or individual customer, chose the fuselage colour). This fine example of the breed is seen here at GVFWE 2009, at Kemble, and is now owned by Mr Roy Palmer; it was on the Danish register, prior to being recovered to Britain.

As well as examples for the civilian market, the  DH60 (as the DH60T) was sold to various military customers. The Royal Air Force was not totally convinced, however, and it wasn’t until the sweep of the wings were altered, to enable pilots to bail-out easier in an emergency, and an inverted version of the Gipsy engine fitted, that it finally adopted the Moth as the DH82a Tiger Moth. The rest, as they say, is history.

Folland Gnat T.1
Folland Gnat T.1

Kemble Airfield has many interesting residents. The local aviation company, Delta Jets, is better known for it’s fleet of Hawker Hunters, but it also owns this Hawker Siddeley Gnat T.1, XP502. Currently, the Gnat is located on the old airfield ’signal square’ , a relic of the early days of flying, when a pilot would join the circuit overhead, and look down at the square, to see which runway was in use (shown by means of black ‘dumbell’ markers) and even confirm WHERE he was (the two-letter code for Kemble, KM, is still there). XP502 is in spurious ‘Red Arrows’ markings, to commemorate the fact that Kemble was the home of the ‘Reds’ for nearly 15 years, from 1969 to 1983; the last four years of which had seen the Gnats supplanted by the BAe Hawk. Indeed, the Postmaster at nearby Cirencester still sometimes gets mail addressed to ‘The Red Arrows, RAF Kemble’ – it is carefully forwarded to their present home at RAF Scampton.

The Gnat was designed by W.E.W. ‘Teddy’ Petter and was the outgrowth of another Folland design, the lightweight fighter known as the Folland Midge. Although neither the Midge nor the single-seat Gnat were adopted by the Royal Air Force, a development, the two-seat Fo.144 Gnat Trainer, was finally ordered on the 7th January, 1958 as the Hawker Siddekey Gnat T.1 (the Folland concern having been taken over by Hawker Siddeley in 1959), and intended as an advanced trainer to lead into the English Electric Lightning, yet another aircraft which had been designed by W.E.W. Petter!
XP502 was the very first Gnat to enter service with No 4 Flying Training School (7th November, 1962; construction number FL.517), and served with this unit until 1978. Withdrawn from use, it became an instructional airframe at RAF St Athan in South Wales, before, finally, being auctioned off.
The Gnat proved to be a highly manoeuvrable aircraft, and the ‘Reds’ predecessors, the ‘Yellowjacks’ showed just how suitable it was for display flying. Many of the Gnats used by the ‘Red Arrows’ had the infamous ‘Fuse 13′ modification, whereby that particular fuse was removed, to allow maximum roll rate via the ailerons. This gave rise to the famous Gnat ‘twinkle roll’ . The ‘Fuse 13′ modification was rescinded in 1972.
Gnats are regularly seen on the European air show circuit, as a popular ‘jet warbird’, but were also the ’stars’ of a 1991 feature film, ‘Hot Shots’, a parody of ‘Top Gun’! The film, which showed the Gnats painted as US Navy aircraft, featured Charlie Sheen and Lloyd Bridges.

Snake Pass, A57 Glossop to Sheffield

Snake Pass, A57 Glossop to Sheffield

I am from Derbyshire, and intensely proud of that fact. I am fortunate enough to be able to travel back fairly often, and visit friends and relations in the region. A few weeks ago, I landed at Manchester Airport (ICAO code, EGCC), the third-busiest airport in the UK and only a few miles from the boundary of the Peak District National Park. I have family in Sheffield on the other side of the Pennines.

I chose to travel the A57 road which runs from Glossop in Derbyshire to Sheffield in South Yorkshire. Part of this road forms the notorious Snake Pass, which winds it’s way through the National Park from west to east. Here you can see a typical piece of Peak District scenery on the A57, complete with pines and a rushing stream.

One thing the Snake Pass is notorious for is becoming blocked by snow, almost every winter, and its easy to see why!

Control Tower, Kemble Airfield

Control Tower, Kemble Airfield

Well, the 2009 GVFWE has come and gone…..and it was a roaring success. Elements from previous events seemed to blend easily with the new, thanks to some excellent work by Glen and all at Kemble Aviation,  (here is a shot of the control tower at Kemble, ICAO designation EGBP) . I know that those of us who were ‘carry-overs’ from previous years found ourselves thoroughly at home. Kemble, of course, is used to holding some first-rate aviation events, including an Air Day (this year a two day show) featuring some of the local Delta Jet fleet. GVWFE was re-worked to include a one-hour flying programme, in the middle of each day, which also featured sparkling displays by a Delta Jets two-seat Hawker Hunter, in the colours of No.  111 Squadron, RAF, and many other aircraft. 

All in all, a great start to a ‘new’ edition of this classic event.

Fairchild Argus

Fairchild Argus

Elegant and efficient, this product of the Fairchild Engine & Airplane Corporation formed the backbone of the Air Transport Auxiliary fleet during World War Two. The ATA had been set up in 1940 to transport urgent items (including mail) between airfields. It rapidly evolved into an organisation which ferried the planes themselves, from factories, Maintenance Units and Repair Stations to the frontline units. A wholly civilian staffed organisation,  the ATA (motto, Aetheris avidi, ‘Eager For The Air’) was headquartered at White Waltham, near Maidenhead, Berkshire, and took female as well as male applicants. They eventually flew everything from Vickers-Supermarine Spitfires to Avro Lancasters, from Fairey Swordfish to Consolidated Liberators. One of the needs of this organisation was for a fleet of air taxis, four-seat machines, which could pick ferry pilots up and return them either to base, or on to another ferry job. The Fairchild Model 24 had been in production in the USA since 1932, as a comfortable 4-seater, but was quickly subject to a wartime order for the US Forces as the UC-61, and was an excellent communications and utility machine. Powered either by a Warner Scarab radial engine (this machine was called the Argus II in RAF parlance) or the Ranger L-440 inverted 4-cylinder inline engine of 200hp (the Argus III), it was the latter which was the main version used by the ATA. The Argus was supplemented by numbers of twin-engined  Avro Ansons and Airspeed Oxfords, for the larger jobs. The war-time flying took its toll; 173 members of the ATA lost their lives, including the world-famous aviatrix, Amy Johnson, who died in 1941 after crashing an Airspeed Oxford into the Thames Estuary.

The Argus has a specially designed, oleo-damped undercarriage, which allows a high rate of sink during landing. This, along with immensely strong main spars in the wing, made from laminated spruce, all contributed to a rugged airframe, and, therefore, a fair number of post-war survivors. Production of the Argus continued into peace-time, and the last civilian Model 24 left the factory in 1948 – a most creditable run.

This aircraft, G-BCBH, is a Fairchild 24R-46A (Modified); it was the 975th aircraft of the type to be built, and is powered by the Ranger L-440-C2 engine. Note also the brass sheathed leading edges of the wooden twin-bladed propeller, which helped prevent damage. Bravo Hotel is in a rather splendid yellow and white finish, which reflects the afternoon sunshine at GVFWE. It returned to the British register in 1983, having spent some time on the South African register as ZS-AXH. A most pleasing sight to see, and a very handsome restoration.

The rare made commonplace – G-AIYS, DH 85 Leopard Moth March 6, 2009

The rare made commonplace - De Havilland DeH 85 Leopard Moth
The rare made commonplace – De Havilland DH 85 Leopard Moth

Geoffrey De Havilland was a skilled aeronautical engineer, of that there was no doubt, but he was also a passionate lepidopterist, and named many of his early creations after various species of moth. The Leopard Moth was designed in the 1930s to provide a relatively swift (c. 130 mph) ‘gentleman’s aerial carriage’ (one pilot, two passengers). The prototype won the King’s Cup Air Race in 1933 at over 139 mph, flown by Geoffrey De Havilland himself. The fact that De Havilland had forsaken the fabric-covered steel tube formula of the Leopard Moth’s predecessor, the DH 80 Puss Moth, and instead built a strong, sturdy ‘box’ from plywood, giving a structure of lower weight, enabled the aircraft to fly faster and further. The DH Gipsy Major 1C engine puts out around 142 hp, which gives a cruise speed close to 120mph, and a range of over 700 miles.

This specification lead to a  spate of orders, with no less than 133 being built before production finally ended in 1936. Many Leopard Moths were ‘impressed’ by the RAF at the start of the Second World War, and they proved to be an excellent liaison type,  ferrying personnel from airfield to airfield.  A number survived the war to be disposed of by the military at the famed post-war sales held at RAF Kemble. Just 14 Leopard Moths are still in existence, with 5 of these being in airworthy condition in the UK.
G-AIYS was originally sold in Egypt, but went onto the Iraqi register as YI-ABI, and was used on charter work from Baghdad.  Some distinguished names in the pantheon of aviation followed as owners, including the Surrey and Kent Flying Club at Biggin Hill, Torquil Norman, Sir William James Denby Roberts (of Strathallan Collection fame), and Victor Gauntlett (not just of oil companies and Aston Martin, but a trustee of the RAF Museum).
Here you can see Yankee Sierra, resting in the sun at GVWFE Keevil, with the port wing folded; wing folding was important in the 1930s, when aircraft were towed from place to place more than they are now, although wing folding will be useful in reducing hangarage costs. Yankee Sierra is now owned by Mr Ronald and Mrs Valery Gammons, and is kept in truly splendid condition – a classic British aircraft.

Miles Messenger, G-AJOE
Miles Messenger, G-AJOE

Developed from a Second World War design for the Royal Air Force , and used primarily as a liaison aircraft - one was notably used by the then General Montgomery, as a personal transport – this Miles design showed excellent short-field performance; you can see here the generous trailing-edge flaps which contributed to this. The M.38 Messenger was a development of the twin-tailed M.28 Mercury, and the post-war civilian Mk. 2A was built at a facility in Newtownards, Northern Ireland. The aircraft were then flown over to the Miles factory at Woodley, near Reading, where they were painted and upholstery fitted. Powered by a Blackburn Cirrus Major 3 engine, of 155hp (the same as the Auster J5K, and the Chrislea CH3 Super Ace Skyjeep Mk 4), the Messenger was a popular four-seater touring aircraft, but unfortunately production ceased with the 71st example in 1948.

G-AJOE had an interesting start; it was bought in  in April 1947 by Anthony Bingham Mildmay, 2nd Baron Mildmay of Flete. Unfortunately, the aristocratic steeplechase rider (who was credited with introducing Queen Elizabeth, the Queen Mother, to the sport of horse racing) disposed of G-AJOE fairly swiftly, and it was back in the hands of Miles at Reading by October 1947.

After a series of owners, the aircraft is now in the hands of Peter Bishop, and has been restored in a traditional Miles cream and red livery. One of only a handful of Miles aircraft still flying, it appears regularly at GVFWE and other events.

A faster dragon………… February 20, 2009

A faster dragon.....
A faster dragon…..

Edward Hillman had built a economical charter and scheduled airline business using the safe, affordable De Havilland DeH 84 Dragon – the Dragon had arisen because Hillman’s DeH 80A Puss Moth wasn’t big enough, and he negotiated with the company for a ‘twin-engined Puss Moth’. What he needed now, in the late 1930s was a ‘faster Dragon’. Enter the Dragon Six (sometimes called the Dragon Rapide, and later just Rapide) with its Gipsy Major 6 engines of  200hp, and capable of carrying eight passengers, it was an instant success in the civil market. There was military interest too, with light bomber varients being used during the Spanish Civil War, and sold to smaller nations such as Lithuania. The Royal Air Force needed radio and crew trainers, as well as communications and air ambulance machines. The Dragon Rapide put on ‘warpaint’ and became the Dominie T.1, the vast majority of them being built by Brush Coachworks, at Loughborough in Leicestershire. G-AGTM was one of these, built in 1944 and originally bearing the RAF serial NF875.

Postwar, it was sold to the Iraq Petroleum Transport Company Ltd, and was used around the Middle East, as many other Rapides were, on general oil support and communications work (the aircraft was on the Jordanian register as JY-ACL). Brought back to the UK, G-ATGM was used by the Army Parachute Association to support their activities, and wore a very attractive colour scheme, which included an oversize Parachute Regiment badge on the nose, and the name ‘Valkyrie’. Next came a move to the Imperial War Museum, Duxford for pleasure flying, and another re-paint. This time the aircraft wore an all-silver Royal Navy colour scheme, and markings for HMS  Hornbill, Royal Naval Air Station Culham, in Oxfordshire. The aircraft operator, whilst at Duxford, was Russavia, the brainchild of the late, and sadly missed, Mike Russell.
Finally acquired by Air Atlantique’s Historic Flight, the aircraft is now serviced and maintained in superb condition, being fitted with DeH Gipsy Queen 3 engines driving Fairey Reed propellers.  The aircraft is used, in the main, for specialist charters and air show work. She is seen here, safely housed in one of the WW2 hangars at Hullavington during GVFWE (note the 621 Volunteer Gliding School Viking T Mk 1 glider in the background). At an age when most people think of retirement, ‘Tango Mike’ is just getting her second wind – underneath her wings!

SOCATA? Sud-Aviation? Gardan? French aviation alphabet soup…. February 16, 2009

SOCATA Gardan GY80-A1A Horizon
SOCATA Gardan GY80-A1A Horizon

This pretty, retractable-gear four-seater tourer is shown parked at the edge of the old ’signal square’ at the former RAF Abingdon (now Dalton Barracks, an Army base).

It was subject to the typical series of name changes and take-overs which were part of both the French and British aviation industries in the 1960s and 70s. Designed by Yves Gardan, then licensed to the SOCATA plants at Nantes and Rochfort, who built it for the Sud-Aviation concern!

Whoever can take credit for it, this is a neat, efficient design, the Sud-Aviation Gardan GY80-180 Horizon is typical of the French ‘club’ aircraft, suitable for instruction or touring. Powered by the ever-reliable Lycoming O-360-A1A, driving a Hartzell HC-C2YK propeller, this GY80 has a range in excess of 700 miles; you could have seen it at Leeds-Bradford International Airport, West Yorkshire (IATA code, LBA; ICAO code, EGNM) in 2002, awaiting a buyer. It was formerly on both the Danish (OY-DTN) and Swedish (SE-FGL) registers.

In praise of the corrugated iron hut……… February 8, 2009

Corrugated iron huts, Keevil
Corrugated iron huts, Keevil

It all started with an officer in the 29th Company, Royal Engineers. Major Peter Norman Nissen (1871-1930), needed a fast, easy-to-erect building which would offer storage and living space in the field. Since this was 1916, the need was great indeed, and production of the hut, made from curved sheets of corrugated iron was approved immediately. A single hut took 54 sheets of curved corrugated iron, 10 ft 6 ins high and 2 ft 2 ins wide, and a specially braced framework.  By the end of the First World War, around 100, 000 units had been manufactured.

Athough small scale production continued between the wars, it was only the outbreak of World War Two that caused a massive expansion of the building programme. Although the huts could be taken apart, and moved to new locations as required, many formed the backbone of ‘permanent’ buildings on airfields, army barracks, and naval bases worldwide. There were various versions of the hut built, including the  Romney Hut (British) and the Quonset Hut (US). The Quonset Hut was named after Quonset Point, where the Davisville Naval Construction Battalion Center was located (Davisville being a part of North Kingstown, Rhode Island).

These huts are located on Keevil Airfield, Wiltshire, and look to be modified Quonset huts, as these were considerably larger than the British versons, and I have seen a photograph of similar huts at Keevil in 1943. This is possible as Keevil was, at one time, Army Air Force Station 471, home to several US Army Air Corps units. These included the 81st Airdrome Squadron, providing communications and other support to AAC flying units. Herbert Hawkes, who served with the 81st described the conditions at Keevil in 1943 as, ‘mud’!

The huts now serve a variety of uses, the one on the left of the photograph being used by Bannerdown Gliding Club, an RAF GSA Gliding Club, affliated to nearby RAF Lyneham.

Postwar, huts of all three types continued in use in the UK, and in other countries. They housed farm animals and equipment, many when former airfields reverted to agricultural use; they were used to house PoWs, as well as ‘displaced persons’, and, above all, they continued their military careers on bases both large and small. As for Major Nissen, he received a small payment for his efforts, but the Distinguished Service Order from a grateful nation.
