Darren Priday Dornier Do17 Lecture

Darren Priday
On Tuesday 13 September 2015, the Rugby Aviation Group and the Midland Air Museum held their annual joint meeting for which MAM's chairman, Barry James, had attracted Darren Priday, the Michael Beetham Conservation Centre Manager at the RAF Museum Cosford.

Darren is responsible for the conservation of the RAF Museum aircraft and was closely involved in the recovery, transportation and conservation of the Dornier Do17, which was lifted from the seabed off the Kent coast near Deal on 10 June 2013 after 73 years in its watery grave. 

The following images provide some background to the aircraft recovery and clean up and although there is an identification plate, the true identity of the aircraft has so far not been established with certainty. It is believed to be a Do17Z registered 5K+AR and serial number 1160.

Following its arrival at the conservation centra of the RAF Museum at RAF Cosford, the aircraft remains were placed in poly tunnels. The project benefitted greatly from scientific assistance to determine the best process for cleaning up the airframe with causing further damage. The resulting cleaning agent was a citric acid solution which was sprayed onto the aircraft from various angles solution to gently remove the encrusted marine "crud". Not only did it perform well as a cleaning agent, it was also environmentally friendly and could be disposed off via the normal drains, saving the project on disposal cost.

The lecture also went into some of the more technical details and Darren showed examples of components in their before and after states.
The future of this unique relic of the Second World War is being planned and it is most likely to remain at the RAF Museum at Cosford, due to its fragility. In order to preserve the mostly delicate remains an enclosure will be designed with environmental controls, e.g. humidity, temperature etc. to ensure no deterioration will occur. The target date for the Dornier to go on public display is in 2017.

Our thanks and that of the Midland Air Museum to Darren for an interesting lecture.

Brief history of the Dornier D017

Dornier Do17
The Do17 was designed as a high speed freight and mail place for the German State Railway and Lufthansa respectively based on a specification issued in 1932 by the German Ordnance Department. Work began the same year resulting in a full scale mock up the following year.

The specification called for an aircraft with special features to conceal the fact that the design was in fact a medium bomber for the future Luftwaffe. After the First World War Germany was not allowed to have armed force, but with the Nazi party coming into power with Adolf Hitler as its leader, the armament build up was conducted in great secrecy.

Dornier Do17 Three View Drawing
The original design had a single fin and was to have been powered by two Daimler Benz DB-601 engines, but as they were in short supply and given as a matter of priority to Willi Messerschmitt  Me109 and Me110 designs. Also, the first models had a round nose in front of the stepped cockpit, but following experience in the Spanish Civil War the nose was changes to the distinctive faceted glazing as shown in the the three view drawing.

Some versions had BMW engines, but the Do17Z, the most prolific version, had Bramo engines, which left the aircraft short on performance and combat range although later versions of the engines provided some small improvements.
With the latter versions of the Bramo engines the aircraft could reach a maximum speed of between 217 and 255 miles at sea level and 5000 feet respectively with a bomb load of 17,000lbs.

The Dornier D017 remained in frontline service throughout the Second World War, but its role as a fighter was quickly taken over by the more capable Junkers Ju88 and in the medium bomber role by the Heinkel He111.

Having a slender fuselage ending in a pointy tail earned the aircraft the nickname "Fliegender Bleistift" or "Flying Pencil" was said to have been hard to hit in air to air combat in by flak.

Vulcan at Coventry Airport on 13 September 2015

As most aviation minded people know, this year will see the grounding of Vulcan XH558 after 8 years on the displays circuit. Sad, of course, but more so, happy that we had the opportunity to see this icon in the air drawing crowds by the thousand to every appearance it made.

On Sunday 13 September 2015 was going to be the last Vulcan To The Sky Club's members day with the Lady herself still flying. The visit to the Classic Air Force was a fitting one as a potential Avro future flying successor made an exceptional appearance. The Avro Shackleton of the Shackleton Preservation Trust made not just an appearance on the flightline to run up its Griffon engines, but performed a taxi run along the crowd line. On its return "leg", John Corley, who was at the controls, stopped in front of the crowd, put on the brakes and made the Griffons produce the sound that made the Shackleton famous as the "Growler".

The day started under glorious sunshine, but as the time went on more and more cloud appeared and by the time the star of the day, XH558, appeared it was decidedly grey. 

The Vulcan To The Sky Trust was represented with the Vulcan Village as well as a number of people, including VTTST Chief Pilot Martin Withers, seen in the picture on the right after a visit to the flightline. Several other V-Bomber crew members were in attendance, which included AEO Barry Masefield and Bob Tuxford, and in the main hangar each related their own story to those gathered. Those stories, as expected, were entertaining, full of history and humour, which were very much appreciated by those gathered to hear them.

Vulcan flyers relate their stories, 

The Classic Air Force was represented with many airframes, some airworthy, some less so and there was plenty opportunity to take a "discounted" flight in either the Proctor or the Dove, though the former was fully booked very early in the day. Both aircraft flew non-stopped between the various displays.

Here are a few pictures of what was on show on the ground.

The De Havilland Dove was no less busy, eager passengers forming a long queue for the experience

The flying for the day was opened by this beautiful 1937 built De Havilland DH-87B Hornet Moth.

The Venom was also displayed with great panache

Dan Griffith returns to the flightline at the end of his display

And so does John Corley
And then, as the Venom was taxiing in, the final display item having made her way down from Robin Hood Airport near Doncaster (better known to most of us as RAF Finningley) made her entrance, Avro 698 Vulcan BV2 XH558, the aircraft everyone on the airport and well beyond its fences had come to see. This has become known as the "Vulcan Effect" and clearly, from reports after the show and video clips posted on social media and YouTube, thousands of people had found somewhere to see, photograph or video XH558, but more importantly had come to bid her farewell in her last few weeks as a flying.

XH558 completed her first pass over the Baginton runway

Topside pass? This is not something the Vulcan is very good at, much better at pulling the crowds

Bomb doors open in this pass, but no undercarriage down pass.
The final display at Coventry Airport by XH558 was not a full one. Although the commentator quoted Shoreham as one of the reasons, but we know that the aircraft does not perform any high energy manoeuvres so is not restricted. The second reason given was perhaps more plausible that being the vicinity of housing areas close to the airport.

Only twice was the roar of the Olympus engines heard, ones when the aircraft arrived over the runway, the second on its final pass when it climbed out for its departure back to base at the conclusion of her display at Coventry Airport. 

The atmosphere in the crowd during her display was one of strong emotions and, to use a cliché, "not a dry eye in the house", including mine. Having joined the supporting club back in 1993, shortly after XH558 was delivered to Bruntingthorpe, there have been many great moments, many pennies invested to keep this lady flying and many friends made, most of whom were present on this memorable day in September 2015. I am proud to have been associated with this beautiful lady and with my name printed somewhere on her bomb bay doors that association lives on together with many others, whose names are also displayed on those same bomb bay doors.

Just a couple more opportunities now to see XH558, Gaydon (4 October) and somewhere along its southern route over the weekend of 10/11 October 2015.

Victory Show, Cosby, 6 September 2015

The annual Victory Show is a great military spectacle that combines military exhibits and mock battles with an air display of mainly vintage aircraft, some of which taking part in the main battle of the day. This year saw exceptional crowds with the prospect of the Vulcan To The Sky Trust's XH558, but helas she could not make an appearance have experienced an undercarriage issue the previous during her displays in Northern Ireland (Portrush) and Scotland (Prestwick). This made for a welcome gap in the flying display mid-afternoon to put down the cameras and have a drink.

Your author had made the decision to attend on the Sunday (because of the planned display by Vulcan XH558), which turned out to be a fabulous day with ideal lighting conditions for photography, especially in the latter part of the afternoon.

Participation in the flying display is growing year on year and on the flightline were some of the old favourites the Hardwick Warbirds P-51 Mustangs "Marinell" flown by Rob Davies and "Janie" flown by Maurice Hammond, Peter Vacher's original Hurricane I, Bückers Bestmann and Jungmeister from Breighton to name but a few. Another frequent visitor is the Grace Spitfire, flown by Richard Grace, this year accompanied by the new and beautiful Seafire III, flown by Dave Puleston, the pair flying some excellent close formation sequences as exemplified by the picture above.

Other first were the newly restored Bristol Blenheim I expertly displayed by ARC's John Romain, the ARC HA-1112 Buchon, Hardwick Warbirds Stearman, German registered Yak-3M, D-FLAK, now owned and flown by Will Greenwood and Gloster Meteor T7 of the Classic Air Force shown off to superb effect by Chief Pilot John Corley. There were also a few interesting visitors in the shape of Richie Piper's camouflaged T-6 Texan, a red and silver DH-82 Tiger Moth and lovely looking  butterfly-tailed Beech Bonanza.

Here are some of the images of the day in no particular order.

Unfortunately this North American T-6 Harvard did not display. It is owned and flown by Richie Piper.
This brightly coloured De Havilland DH-82 Tiger Moth was also amongst the visitors
Yakovlev Yak-52 trainer G-BXJB was also a visitor seen here departing Cosby at the end of the air display.
This Piper L-4 Grasshopper is a regular acting as a spotter for the main battle.
And finally, standing behind the flight line is not always good for taking photographs of landing and departing aircraft, but it can provide other opportunities such as the small image at the start of the blog that shows the nose of the Blenheim with "Sally B" approaching Cosby.

Dave Puleston in Seafire LFIIIc PP972 takes of for Leicester Airport to refuel. Oops Blenheim got its nose in.
Following through, maybe cropping can rescue this one.
Just caught Hurricane I  in this shot of the Blenheim taxiing in after its solo display.
Flightline action: Richard Grace and ground crew member assist Dave Puleston parking Seafire PP972.
The final selection are some of the pictures reproduced in black and white, like the Buchon earlier, which can give the image a period look. Provided the background is "ageless", this works well and Cosby provides opportunities like that.

Bristol Blenheim I...the modern fence and gate could be "removed" from the image.
Not a clue in this image of the era
If you have not been to Cosby, you not just like vintage/WWII aircraft and you like to be close to the action, then you should make you way there next year. 
I'll be back.
