First of all a hearty welcome from myself also to the thread, speaking as a fellow old Filtonian/Fairfordian. (I'm sure I must have bumped into you during my years at BAC Clive). It is thanks to the tremendous skill and dedication of 'designer chaps', such as yourself and ChristiaanJ, that Concorde became this breathtakingly amazing aeroplane that she was. I can't wait to read some more of your informative posts; you obviously have one hell of a story to tell, and can obviously teach us all (especially me) a thing or three. ![]()
Anyway, after that 1980 engine fire incident we did find a couple of small holes in the centrewall and as a result we fitted some ceramic coated steel plates in the vulnerable areas.
But as stated, the fire precautions built in did a good job. In this connection though it is worth saying that the cooling air passing over the engine comes from the ramp bleed in the intake and that it is controlled by 'secondary air doors' in the corners left between the circular engine and the square nacelle. These are there to stop air flowing back from the engine bay into the intake during takeoff and are opened once the pressure diferential between intake and engine bay is favourable. Part of the fire drill was to close these doors so the engine fire was deprived of oxygen, which helps a lot Best Regards Dude ![]() Last edited by M2dude; 21st December 2010 at 08:37 .

But at least we now have another 'written off' British Concorde; I guess this fact obviously pleases some people
I've pulled this quotation out at random from what I have found a rather disappointing sequence of postings. I could write reams about this (and like everyone in this thread I would write as a Concordophile), but I won't - or at least I will try not to. In general I'm with Christian on this, and for the record I think a few 'counterfactuals' should be recorded. I am not trying to reopen a sterile debate - as CJ has said irrevocable decisions have been made and the subject is done and dusted. However, let us remember that: G-BOAF was, and is the property of BA; BAe and now AI are merely caretakers. AI's statement cross-posted from the Heritage website strikes me as a very reasonable statement; we found that your roof is leaking, if you don't get it fixed it is going to get worse rather rapidly; if you (BA) agree and will pay us to do it we will take it indoors and fix it. I don't see any sinister intent here, and given the weather we have had in the UK over the past weeks it must be regarded as a happy, if fortuitous decision! Those who know Filton will also know that there is nowhere that Alpha Fox could be stored under cover except in the hangar where she was first assembled. They will also know that this hangar is buried in the centre of the factory and nobody, in a post 9/11 world, is going to give more or less unrestricted public access to somewhere containing a lot of valuable real estate! So when BA took the decision to locate AF at Filton it must have been in the knowledge that she would live in British weather until some form of shelter could be organised. That it has taken so long to (fail to) organise such shelter is regrettable, but the blame can hardly be uniquely allocated to AI. BA own the aircraft, BAe/AI had a 40% share in building the airframe, RR a 60% share in building the powerplant. IMHO they should all have chipped in to construct some sort of shelter - it was never on the cards that local enthusiasts could have raised enough in a short time. Although 'Dude' says that all the UK airframes were left out in the weather, this is not exactly true is it? 002 at Yeovilton (certainly) and 101 at Duxford (I think) are under cover and receive lots of TLC. It is at least arguable that these early airframes have more historical significance than Alpha Fox. So far as AI's decision to hand back the C of A is concerned, they would have already recognised from the post-Gonesse activity that most people with sufficient expertise on the Concorde design were retired (or worse!) They have enough people to keep a subsonic aircraft going, but Concorde would, I think, require additional experience. AI management would certainly have consulted AI Engineering about this, and I have to say that the then Head of Engineering was someone I know well. He, like me, worked on Concorde in the early days and he is definitely not antiConcorde. I for one would respect his decision. So far as the decision to stop services goes, we all knew they would be cut off sometime.the only question was when. When we were designing the aircraft the general feeling was that she would stay in service for about 30 years, but we also feared that it would only need one fatal accident to bring the whole lot crashing down. [Incidentally, it was that latter philosophy that made us (we hoped) ultracareful with airworthiness issues] In the event it was 28 years and one accident. Even before Gonesse AF were losing money on their Concorde services. One might have thought that they would stop right away, but I suspect that a combination of Gallc pride and politics ensured that they would carry on. But eventually there came a point where, on an airline losing money and in a recession, an unsentimantal and yes, generally unsympathetic, management would have to say enough is enough. What else would you have them do? Continue to fly loss making services so that their rival BA could go on with their profitable? operations? One would have to say 'Get real!' Once AF had decided to stop, what do you expect of AI? They are a company with a duty to make profit for their shareholders. OK, they had a duty, also to support in service aircraft, but that duty does not extend to doing that at a loss. With AF out of it therefore AI had no alternative but to ask BA to shoulder the full bill. I have no doubt that when BA declined to do this AI breathed a huge sigh of relief, but at the end of the day the decision to stop all Concorde services was above all an AIRLINE decision. Sorry to go rabbiting on, but it is a subject that arouses strong emotions! CliveL Reply to this quoting this original post. You need to be logged in. Not available on closed threads. |

So far as the decision to stop services goes, we all knew they would be cut off sometime.the only question was when. I've said something similar (while at the same time being full of admiration and effusive praise for M2Dude). It's worth bearing in mind that at the time (2003 or thereabouts), AI were fighting a battle to keep the A380 project viable (like Boeing with the 747, they'd effectively "bet the company" on the project's success) - and sadly, in terms of business realpolitik Concorde was costing them money, being just a small-run legacy airframe capable of operating profitably for a single customer. Things weren't going to get any better, and as such AI's decision was as understandable as it was regrettable. I have far less sympathy for BA, who acted with what seemed to me indecent haste to permanently mothball the airframes (the press at the time speculating that Branson would try to get his hands on at least one of them), and while the UK Concorde community have a right to feel aggrieved at the way things panned out - the fact that what was left of BAe effectively bowed out of the Airbus consortium, the better to focus on military hardware with the Americans, meant that we'd thrown away any chance of having a say in what happened to Concorde in the end. EDITED TO ADD : In reference to Bellerophon's post below - this was *not* intended to take the technical discussion off-course. I was simply trying to thank Clive for summing up how I felt about the whole situation far better than I ever could. Sincere apologies if this was misconstrued as such.

So many vivid memories from so many people.
I suppose personally I'll always remember the first time that I ever saw Concorde flying as well as the LAST time : The very first, as I posted here many months ago, was in 1970 when I, as a young grotty little RAF erk, was in Swindon and heard this loud roar in the sky over what was then Bon March\xe9 (Now Debenhams). Looking up I saw this amazing sight of 002 complete with her attending Canberra chase plane flying over. (And trailing a sizable black exhaust plume to boot). The very LAST time I saw her flying was in November 2003 at the side of LHR 27R as G-BOAF, the last Concorde ever built and the last one ever to fly, made her final departure out of a very dismal Heathrow bound for Filton. For me, the weather at LHR that day perfectly matched to gloom of the occasion I'm afraid. A really lasting memory I wil always treasure is while my now VERY grown up children were still young, they were (almost) as big Concorde 'nuts' as their dad. Concorde would fly over our house daily and they would run to the window every time they heard the sound of an aeroplane. The general disappointed chant they would come out with was 'it's not Concorde dad, it's just a plane'. For the life of me I don't know why they would develop THAT kind of prejudice and from whom they would get it from ![]() ![]() EXWOK
And I still have to stare wistfully at OAB whenever I drive past the engineering base en-route to Cranebank.
Hopefully she will get a fitting 'home' soon so that more people can marvel at our absolutely beautiful and truly timeless aviation icon Best regards Dude ![]() Last edited by M2dude; 26th January 2011 at 12:49 .

(And ChristiaanJ)
Dude, can I join Christiaan in requesting more information on that '5000' series numbering; I have never come across it before.

Also, I have asked the CAA surveyor who was most likely to have made that reskinning decision for more data. Perhaps he can remember the problem with the forward fuselage skins. Certainly when we were standing together inside 102 last week and talking about fuselage modifications for relifing the aircraft the problem of Component 30 was not mentioned!
And sorry everyone about the \xa330 cost of converting 202 into an airliner, I meant (dumb ass that I am) \xa330 MILLION. ![]() Best regards Dude ![]() Reply to this quoting this original post. You need to be logged in. Not available on closed threads. |

Google was right....
G-BOAB has been moved around LHR repeatedly, and she was indeed parked for some time inside the old "detuner" (engine run-up silencer), which is what that recent "what's this then" post and picture are all about. It's a pity, really.... All the other British Concordes have found a "home" one way or another (except G-BOAF, maybe,, but let's not go into that for the moment), and G-BOAB is slowly becoming the "forgotten" Concorde.

Filton
Save Bristol\x92s Concorde and the Brabazon Hangar
The Brabazon Hangar dominates the south side of Filton Airfield. During the 1960s it became the home of the UK Concorde production line, but Concorde wasn\x92t the first aircraft to be built within this amazing structure. The hangar was originally built during the 1940s to enable the construction of the massive Bristol Aircraft Company\x92s type 167, which is better known as the Brabazon and hence this is where the name of the hangar came from . This giant airliner aircraft had a 230ft wingspan, and was powered by eight pair-coupled Bristol Centaurus piston engines and was Britain\x92s attempt at a non-stop trans-Atlantic airliner. The prototype flew in 1949 six years and \xa33 million after the conception, and sadly the aircraft was already obsolete. The British de Havilland Comet jet-powered airliner was already well on the way and on the other side of the Atlantic, Boeing were developing their 707, and both of these would fly faster and carry more passengers than the Brabazon The prototype flew for a short while and a second turboprop-powered prototype (Brabazon II) was being built when the project was abandoned. Both aircraft were subsequently broken up in 1953. With the demise of the Brabazon project Bristol was then left with one of the largest aircraft production facilities in Europe and therefore the giant Brabazon hangars were put to other uses, these included being used for the production line for the much more successful Bristol Britannia airliner. But the Brabazon hangar has become more famous today as the birthplace of all the British built Concordes, ten airframes were built there, one prototype known as 002, one pre-production known as 01, one development production known as Delta Golf, and of course the seven airliner production airframes detailed below\x85 G-BOAA G-BOAB G-BOAC G-BOAD G-BOAE G-BOAF G-BOAG Concorde 216 G-BOAF was the last Concorde built anywhere in the world, and of course the very last one to fly in November 2003. During her final flight she flew back to her birthplace, to Filton to form a major part of a new planned Bristol aviation museum. The plan was to house the whole of the Bristol Aviation Collection, known as the BAC, in one building, a centre to celebrate Bristol\x92s incredible aviation history, and let\x92s not forget that Bristol led the world. But like so many things in this fast changing world, ideas and directions soon change and as in this case not for the better. Heritage Concorde has heard of one idea that it wishes to push forward with anyone who would be willing to work alongside the group. With next years closure of Filton airfield, one incredible heritage building stands at risk of being ripped down and lost forever, the Brabazon Hangar. So why not use this building as the centre of the history of Bristol aviation and space industry, and in memory of the man who started it all, Sir George White. It\x92s large enough to form one of the most incredible museums in the world; it would be able to house the whole BAC collection with Concorde 216 at the centre, where she was built. This idea needs to be looked into and not dismissed so easily by the people leading the effort for the new museum. Heritage Concorde will start to develop this idea further. Any ideas, any offer of help or advice??? Steve de Sausmarez Reply to this quoting this original post. You need to be logged in. Not available on closed threads. |

Filton and G-BOAF
This is obviously a really emotional topic, we can only hope that good sense prevails and the AAH is preserved, along of course with our beautiful G-BOAF. (When I worked at Filton
many
moons ago it was the largest single span building in Europe, not sure if that is the case now or not).
It would be really nice if the SOUTH of the UK had a non-derilict 'proper' Concorde on display to the public, and good old Alpha Fox would be the ideal example, displayed inside the building where she was born). There was so much activity in that hangar over the years, wouldn't it also be great if examples of as many as possible of the aircraft that were built, part built or modified there could be displayed too. Let's all keep our fingers crossed. Best regards Dude ![]() Reply to this quoting this original post. You need to be logged in. Not available on closed threads. |

Hi Christian,
We chose the components for their environmental tests, and all the AICS components were subjected to acceptance testing when received, which was a bit of a problem sometimes because the BAC goods inwards system was so slow that some of the expensive ADC/DACs that were not quite good enough were returned to Harris, but were out of warranty by the time they were returned. The embargo was not just the 5400 TTL I/Cs but all milspec. components. Its stretching my memory, but AICU1 was the ADC board, 2-5 were the processor, 6-10 were the prom boards. There was a bought in board (AICU 17 I think) that was supplied by ?????, that processed the sensor unit data. The AICS was filled with redundancy, as well as the obvious 2 AICUs per intake, and 4 sensor units, the program calculated the output data with dummy inputs - twice, and if these were correct, the proper inputs were used and the result was output to the doors. On the analogue bit there were two channels for each output and at the end one output was compared with the other and if different a fail was produced. We haven't opened the plan chests with the AICS drawings yet. As well as the 8 AICUs on G-BOAF, we have the prototype AICU that was used on the AICS systems rig.

A very belated reply.
I'm not really sure why I stopped coming here, it is one of, if not
the
most interesting thread on any of the forums I visit - by miles. However, I got back into it a few days ago and realised I was over a hundred
pages
behind. I have been slowly catching up, but I'm still nearly fifty pages behind.
My first question is; what has become of the Brabazon Hangar/ BAe Filton/ G-BOAF situation? Wikipedia just say its all been sold - the airfield at least - but not what the dispositions of all those valuable items, particularly Alpha Foxtrot. Second, just to show I really am reading myself back up to date, I noticed something ChristaanJ said that has some resonance with me.
Quote:
Has anybody here read "The Soul of a New Machine", by Tracy Kidder? It's a pity no book quite like that has ever been written about Concorde... and I can't imagine it could be written today. Too many of the 'actors' have retired, or are not there anymore.... Maybe somebody ambitious could use this thread as a base, and do some interviews, and write "Concorde, From Then to Now" ? You probably don't remember, but I used to be a "scanner engineer" - I finally retired in July last year - but I was involved in the very early days of what are now common place diagnostic machines. At some point in the early nineties, I realised two things. I could write a bit - not incomprehensibly at any rate - and all the people who made the early scanners, did the development work and worked on them in the field before me, were either retired or passed away. I asked the management at the time if I could have a bit of time, perhaps a half day every week, to do the research and do a 'Tracy Kidder' for the EMIScanner. No answer came the stern reply and it never got done. Now I don't think it can be, so it never will. I would love to write 'The Soul of a New Machine' for Concorde, but A) I'm probably too old now and B) I was never part of it, so I probably can't put the passion in to it, certainly not the knowledge, that she deserves. If anyone on here who was part of it who wants to put pen to paper (Oh come on! Who doesn't use a Word Processor - which dates me on its own!) but it doesn't seem to come out right, perhaps we ought to meet? Few of my close friends are engineers or scientists and although they all agree that Concorde was (and is) a lovely looking thing, they simply don't understand why it is that engineers get passionate and dewy eyed about her. They cannot comprehend the difficulties of flying at Mach 1+, let alone Mach 2 for three hours in a pretty frock and thus, the ability to do so just seems 'normal'. The book is there to write; the book of the people, by the people, for the people. Reply to this quoting this original post. You need to be logged in. Not available on closed threads. |
