Established by the road-building Romans at the lowest natural crossing point
on the River Severn, Gloucester has always been a focus for travellers and as a
result both the City and County have a rich transport heritage.

| A De Havilland DH61 Giant Moth similar to Sir Alan Cobham's "Youth of Britain". Alan Blencowe of http://www.alanblencowe.com/FSX_FlightHistory/Aircraft_of_WA.htm informs me that this particular aircraft - VH-UQJ - was owned by Western Australian Airlines and had previously been on the British civil register as G-AAAN. Also known as "Geraldine", VH-UQJ was bought from National Flying Services and was flying with Guinea Airways when it crashed at Wau, New Guinea, on 20 August 1935. Damaged beyond economic repair, it was scrapped on 19 September 1936. | ||
| Perhaps
it is natural then for such similar locations to be linked by air -
and also by an aviation pioneer. Sir Alan Cobham's Flight Refuelling
Limited was based at Staverton during the 1940s while on Bank Holiday 2
August 1929 Sir Alan arrived in Ronaldsway, near Douglas on the Isle of
Man as part of his campaign - sponsored by Sir Charles Wakefield of Castrol fame - to make Britain more air-minded.

| From 3 September 2007 however, Manx2.com has connected Gloucestershire
Airport
at Staverton with Ronaldsway as well as flying from the Isle of Man to
Blackpool, Belfast, Leeds, East Midlands Airport and Newcastle.
Manx2.com - with its slogan of 'Failt Erriu - You're Welcome' -
also serves Jersey from Gloucestershire Airport and in both cases the
flight time is less than one hour. Among the Manx2.com aircraft often seen on these services at Staverton are twin engined Dornier 228-200 which have proved a favourite with passengers across the world. Every one of 19 seats is by a window which is larger than those found in other aircraft in its class, facets of design which reflect the Dornier company's proud history of technical innovation. |

| Originally Dornier Metallbau, Dornier Flugzeugwerke
took over the production facilities of Flugzeugbau Friedrichsafen in
1923 when the latter firm failed. Flugzeugbau Friedrichsafen had combined factories at Weingarten, Warnemunde and the former Zeppelin shed at Manzell and the proximity of Lake Constance no doubt influenced Dornier's continuing prominence in the making of large all-metal flying boats such as the 1924 vintage Wal ( German for "Whale" ) and the giant 12 engined Do X of 1929. Indeed, such Dornier flying boats as the Do22, Do 18 and Do 24 saw service in several armed forced around the world as well as - ultimately - Germany. Dornier also built a series of successful land planes, including the Komet (Comet) and Merkur (Mercury) that were used by Luft Hansa and other European carriers during the 1920s and early 1930s. Dornier built its aircraft outside Germany during much of this period, in compliance with the restrictions placed on German aircraft manufacturers by the 1919 Treaty of Versailles. Foreign factories licence-building Dornier products included CMASA and Piaggio in Italy, CASA in Spain, Kawasaki in Japan and Aviolanda in the Netherlands. Once the Nazi government came to power and abandoned the treaty's restrictions, Dornier resumed production in Germany. |

| Dornier's most significant military aircraft design
before and during World War II was the twin engined Do 17, an example
of which from the Jet Age Reserve Model Collection is pictured above. Developed and first flown in 1934 as a commercial
aircraft in competition for a Lufthansa contract, it was passed over because of its narrow fuselage. Nicknamed The Flying Pencil, it was built on the same design principles as the contemporary British Handley Page Hampden bomber and indeed the Do17 was to evolve into the same role with the newly emergent Luftwaffe in 1935. In 1937 Dornier Do17s of the Nazi Condor Legion - with red bands around the swastikas on their tails - assisted the rebel forces of General Francisco Franco in their ultimate victory in the Spanish Civil War. | ||

| Production continued within Germany and the medium bomber variant saw much service during the early part of World War II including extensive use in the Battle of Britain. The Dornier Do17 later proved to be an effective night fighter defending Germany from RAF Bomber Command and formed the basis for the larger and heavier - although outwardly similar - Do 217, as modelled above by the Night Fighter Special Interest Group of the International Plastic Modelling Society. Two of these aircraft - with rounded glazed cockpits - attacked RAF Kemble on 27 July 1942 but failed to hit any of the parked aircraft that they machine gunned. | ||

||
| Dornier also developed the fastest piston-engined fighter of the war, the two-engined Do 335 Pfeil (Arrow) - modelled above by members of the International Plastic Modelling Society but introduced too late to enter combat service. Its push-pull configuration had originated in World War I when Claudius Dornier designed a number of flying boats with either remotely driven or tandem propellers. There are many advantages to this design over the more traditional system of placing one engine on each wing, the most important being power from two engines with the frontal area (and thus drag) of a single-engine design, allowing for higher performance. It also keeps the weight of the twin powerplants near, or on, the aircraft centre line, increasing the roll rate compared to a traditional twin. In addition, a single engine failure does not lead to asymmetric thrust and in normal flight there is no net torque so the plane is easy to handle. The choice of a full "four-surface" set of cruciform tail assembly at the extreme rear of the fuselage also protected the rear propeller from an accidental ground strike on takeoff. | ||

| Had World War II not ended in May 1945 a planned turbojet version of the Dornier Do 335 might have been built. As it was, with aircraft production was again forbidden in Germany by the victorious Allies, Dornier
relocated to Spain and then to Switzerland where the firm
provided aeronautical consultancy services until once again returning to Germany
in 1954. Apart from the technological dead end of the 1967 vintage experimental Dornier Do-31(pictured above) - whose two Rolls Royce Pegasus engines proved too noisy for vertical take offs and landings in airline service and is now in Deutsches Museum, Munich - Dornier quickly re-established itself with highly successful small short take off and landing transports such as the single engined high wing Do 27 of 1955 ( the first post War production German aircraft ) and twin engined Do 28. | ||

The Do 28 first flew in 1959 with the unusual incorporation of
two Lycoming piston
engines, as well as the two main landing gear shock struts of the faired main
landing gear attached to short pylons on either side of the forward
fuselage. As such it made an interesting comparison with the
slightly older Scottish Aviation Twin Pioneer.
The rounded six seat A and B versions of the Dornier 28 were developed into the more rugged 12 seat Do 28D Skyservant - with rectangular fuselage and engine nacelles - which first flew on 23 February 1966. In Federal German military service from 1971 Dornier 28Ds replaced Percival Pembrokes and were themselves replaced from 1994 by much quieter turboprop powered Dornier 228s which also vibrated a good deal less. Indeed, in 1997, the Hungarian engineer Andreas Gál developed a skydiver-friendly Do 28D conversion with two Walter M601-D2 turboprops and modified three-blade propellers. Of the seven aircraft so converted, HA-ACY is pictured above. | ||

| Meanwhile, 1974 saw Dornier collaborate with French manufacturer Dassault-Bregut to develop the twin engined high wing Alpha Jet, seen here at the Royal International Air Tattoo at RAF Fairford, Gloucestershire, in 2002, This particular machine was 15220 of the Portugese Air Force and Alpha Jets became the standard NATO trainer of the 1970s and 1980s. | ||

| Indeed,
international collaboration continued in the 1980s with the Dornier 228- first flown in 1981 - being
built under licence as early as 1983 by Hindustan Aeronautics.
The Oberpfaffenhofen designed commuter transport featured a new
technology wing, retractable nosewheel undercarriage and Garrett
AiResearch turboprops driving four bladed propellers.
The last Dornier 228 was rolled out in 1998 but Fairchild Dornier became insolvent early in 2002 and eventually became part of EADS. | ||

| While the airliners of Manx2 are a regular sight at the main passenger terminal of Gloucestershire Airport, those travelling along the B4063 near the western part of the property - close to Firfax Aviation and the Jet Age Museum's Gloster Meteor F8 - are often treated to the sight of a very different Dornier Do 228. Also registered in Germany, D-CALM is operated by the Airborne Research and Survey Facility of the Swindon based Natural Environment Research Council. | ||

| As an NERC press release of 25 July 2000 explained:
A new and highly modified survey aircraft is the latest tool to help study our environment from the skies. The Natural Environment Research Council (NERC) is to lease a Dornier 228 to replace the Piper Navajo Chieftain that has given valiant service in earth observation for the past 16 years. Because the new aeroplane can fly further and carry more equipment, it will extend the environmental research programmes supported by NERC beyond the usual land and freshwater studies. We will now be able to produce digital images of shelf seas to help monitor, for example, marine algal blooms. An entirely new range of observations will be possible in earth and atmospheric sciences; we can now study the Earth's gravity and its magnetic field and monitor pollution from ground level up to the stratosphere. Access to the aircraft is the result of an agreement between NERC and the German Aerospace Research Centre, Deutsches Zentrum fuer Luft- und Raumfahrt e.V (DLR). Both organisations participate in European Concerted Action Programmes aimed at increasing co-operation between researchers and ensuring efficient use of research aircraft across Europe. The agreement between NERC and DLR is being finalised this week. The Memorandum of Understanding covers scientific co-operation between NERC and DLR, and includes the three-year lease of the Do228 to NERC on a non-commercial basis. The Do228 will be delivered to NERC in October 2000, and following trials, will be operational in January 2001. NERC looks forward to an increase in collaboration with European colleagues in using this exciting new facility for environmental research, survey and monitoring. | ||

| Airborne remote sensing provides an efficient method for the rapid collection of data over a specified area. Consequently it is a cost effective means of monitoring the terrestrial, freshwater, marine and atmospheric environments, provides a transitionary scale with which to validate satellite data and enables the rapid acquisition of data for sudden or unexpected events, such as floods and earthquakes. Since 1983 the NERC's Airborne Research and Survey Facility has supported a wide range of applications, including environmental science, geomorphology, archaeology, ecology, geologic surveying, pollution control and disaster management. | ||

Data from D-CALM is processed by the NERC's data analysis team at the Plymouth Marine Laboratories and then archived at the National Earth Observation Data Centre (NEODC). Currently the ARSF provides radiometrically corrected hyperspectral data from the AISA Eagle and Hawk instruments; ground height information from the Leica ALS50-II; and digital photography. Additionally the Dornier's atmospheric instrument capability compliments that offered by the NERC Facility for Airborne Atmospheric Measurements. The ARSF supports projects across the UK and the North coast of continental Europe, though the facility has supported campaigns with locations as distant as Svalbard, Ethiopia, Chile and Australia. This service is available free of charge to the UK research community (subject to peer review) and the facility is a member of the European Fleet for Airborne Research. |

| In the early part of 2010, D-CALM appeared on British national TV news as one of the few aircraft that could relatively safely explore the ash cloud produced by the Icelandic volcano Eyjafjallajoekull that was disrupting jet flights in British airspace. | ||

| D-CALM also appeared at the Royal
International Air Tattoo in 2011 along with an example of its bigger
sibling, the 30 seat Dornier 328. Seen approaching Fairford above and on the
ground below, Skyworks airlines Dornier 328-110 ( constructors number 3021 )
was Swiss registered as HB-AES and visited on behalf of the Swiss Air Force
to support the Patrouille Suisse aerobatic team.
First flown on 6 December 1991, the Dornier 238 combines the same basic supercritical wing of the Dornier 228 with an all new fuselage section for three abreast seating (offering more width per passenger than the 727/737). Market research in the mid 1980s identified a need for such a modern fast-cruising regional turboprop airliner and development work began in 1988. Composite materials were used in a number of areas to reduce weight including the tail and the blades on the Hartzell propellers while the flight deck featured a five screen Honeywell Primus 2000 EFIS avionics system capable of Category IIIa landings with a head-up display. Industrial partners on the 328 included Daewoo Heavy Industries (fuselage), Aermacchi (nose), Westland (nacelles) and Israel Aircraft Industries (wing), accounting for 40% of the aircraft's construction. Variants of the 328 were the initial production standard 328-100 - first delivered in October 1993 - the standard 328-110 with a larger dorsal fin, heavier weights and greater range, the 328-120 with PW119C engines and improved short field performance and the 328-130 with progressive rudder authority reduction with increasing airspeed. The last 328 was delivered to Air Alps Aviation in Austria in October 1999. | |
