    I forgot to mention there is a very good book on the Britannia – its called “The Whispering Giant in Uniform” by David Berry. ISBN 0952771500. It was published in 1975, so it may be difficult to get your hands on in bookshops, but your local library may have a copy – mine has!

    Canadair produced a piston engined maritime recce aircraft based on the Brit, it was the CL-28 Argus. 33 were built for the RCAF. They also built the CL-44 which would have had Orion engines, but as development was cancelled they were Proteus powered. 12 were built to equip 437 Sqn RCAF and named Yukon. They were followed by 28 CL-44D with a swing tail They were initially operated by Seaboard World, Flying Tiger and Slick Airways. There were 2 unbuilt Bristol projects, the Type 189, a maritime recce aircraft for RAF Coastal Command to replace the Shackleton, dropped in favour of the Nimrod and a cargo aircraft, the type 195, which would have been called “Britannic” which eventually ended up as the Belfast.

    The Brit was a really nice aeroplane. I flew from Lyneham to Singapore in RAF Brits a number of times, they were quiet, comfortable aircraft and had very good reliability once the engine icing problems were overcome. RAF Brits had the seats facing backwards, which was standard RAF procedure in those days. I also flew Nairobi – Gatwick – Nairobi over Christmas 1965 in a Transglobe Brit, also a very good trip.

    I’m working on cleaning up some Britannia Pics at the moment, when I’ve got them done I’ll post them on this thread.

    I’ve just dug out this picture of G-ALBO with the Orion in the Port outer position. I took it at St Athan in 1963 when the aircraft was used as a training aid on the Airfield Training phase a 4 school of Tech Training.

    Clearly a lot of KLM Fans out there, perhaps they are better on long haul – I can’t comment as I’ve never flown with them.

    I’ve also flown the Aberdeen – Brussels route with BMI in an Embraer 135, it was much better, nice tidy aircraft with no visible defects, more red wine than I cared to drink and a young lady flight attendant with the whitest teeth I’ve ever seen!

    My daughter recently flew Eastern Airways, Aberdeen – East Midlands, she said it was onee of the best flights ever, anyone like to comment on Eastern?

    My previous answer is the “official” published reason. Of course there were those at Bristol who were convinced that the Orion was a better engine than the Tyne and that stings were pulled by Rolls Royce who wanted the Tyne to go into production – which of course it did!

    You can choose which version of the “truth” you wish to believe!

    Speculating about which was the better engine will of course be just that.

    Once the problems with the Proteus icing were sorted it was a good reliable engine, and Big turboprop aircraft like the Britannia were rapidly becoming obsolete as the Turbofan filled the flight range that the bigger turboprops would have filled.

    The Orion was a straight through flow engine with a free power turbine,(that is the Turbine which drives the prop is not mechanically connected to the gas generating part of the engine). It was being developed because the Proteus engines in the Britannia were insufficiently powerful to get the best from the aircraft, not to mention the fact that they had an icing problem caused by the reverse flow layout. Both the RAF and BOAC were operating the Brit with the Proteus. The Ministry of Supply decided to order the RAF second batch of Britannia’s with the Proteus, and BOAC decided that they did not want to continue alone and requested to be removed from their obligations to support development funding. So basically with all funding removed from the project in 1958, it was cancelled. The Tyne which was also being developed (and funded by the MoS) at the same time benefitted from the decision and development work continued on it with successful results.

    There was originally funding for 6 prototypes for bench and flight testing, the first bench run was on 10 Dec 1955, and the first flight test was on 31 August 1956 in the port outer position on G-ALBO.

    I last saw the Orion in that location in G-ALBO at St Athan in December 1963. G-ALBO was broken up at St Athan sometime later, what happened to the engine I don’t know.

    Most airlines these days don’t bother to feed you much on short haul hops, so my expectations were not much anyway, however the in-flight snack was positively awful! Back in the good old days when I flew the Inverness-London route with good old Dan Air, the seafood platters were truly excellent, how the world has changed!

    If American Airlines is worse than KLM, I’ll avoid flying with them. When I see things on an aeroplane, which are obvious and easily fixed, but haven’t been, I seriously question the companys maintenance standards. A crazed outer window pane means that it is structurally weakened, this removes the redundancy given by having inner and outer panes – windows are primary structure, so I’m not talking cosmetics!

    Perhaps it is as well that KLM have got some new aircraft on order!

    I got the sad news from Ali’s wife a couple of days ago and am very sad. I knew Ali very well. We met on this forum, and we met up on a number of occasions, I stayed overnight with the family before the East Fortune meet up. We spent most of the evening exploring the watering holes of his home town. I am going to miss him greatly, he had the ability to listen to this old mans “war stories” without yawning.

    Saying what you mean is important, getting it wrong can can be embarrassing! This is a true story! At RAF Kinloss a few years ago it seemed that every airman on the married quarter site was determined to have a shed or greenhouse or gazebo or something in his garden. The CO decided that things were getting out of hand and that the place was starting to look decidedly untidy and unmilitary. He ordered OC Admin to put out an order prohibiting the building of any more such things without permission. The order read ” No airman is to have an erection in his back garden without the prior consent of OC Admin Wing”.

    Back in the old days when there were lots of RAF stations and lots of airmen, an LAC was posted to a quiet little station somewhere in England. On arrival he was told that he would become the SWO’s runner. (The Station Warrant Officers messenger). The SWO’s brief was simple. 07:30 arrive at SHQ. 07:31 fill kettle and put on to boil. 07:32 fill watering can and water the garden outside the HQ. 07:50 brew tea. 07:55 pour SWO’s tea, milk, one sugar. 07:56 place tea on SWO’s desk for his arrival at 08:00. The LAC follows this routine for a week, and is doing well until friday morning when the heavens open and the rain pours down. Good he thinks, just the tea to make. The SWO arrives at 08;00 as usual. “Made the tea laddie?” “Yes Sir!”, “Watered the garden?” “No Sir!”, “Why bloody not?” “It’s thowing it down outside Sir” “You’ve got a bloody raincoat hav’nt you”.

    Hi Tim, The problem you have in identifying the aircraft that crashed is not new. As soon as you start doing any serious research into the history of individual aircraft you run across conflicting information. The official history of any RAF Squadron is compiled from the Sqn Record book (RAF Form 540). This is compiled by the Sqn Adjutant on a monthly basis and records all significant events that have happened over the previous month. Sometimes mistakes occur, and if not noticed and corrected, become the official story. I was 12 Sqns Warrant Officer from June 1999 until I retired from the RAF at the end of 2001. During that time I did some research on the Sqn’s history, and J7946 is recorded as having been the aircraft crashed on that occasion. So that’s the official story, but perhaps the Adj got it wrong!! Anyway the previous photo was not of 12 Sqn’s Fox’s, those were Belgian ones. So here, from the Sqn Archives are a couple of shots of J7941.

    G-AHLL certainly did’nt survive, it was broken up for spares in February 1960. G-AJXB went to Sweden in August 1956 and became SE-BCU, after that who knows?

    We had considerable discussion on this subject about a year to 18 months ago. Having worked on both types of engine I can assure you that a properly maintained sleeve valve engine is just as reliable as any poppet valve engine, and you don’t have to check and reset valve clearances every couple of hundred flying hours! Checking and resetting valve clearances on a radial engine is one of the most time consuming and tedious jobs an engine fitter has to do, and if you get it even a little bit wrong the performance of the engine suffers big time! Give me big Bristols any time!

    There are a few to choose from. ND784 had an Armstrong Siddeley Mamba mounted in the nose in 1947. NG465 had a RR Dart in the nose from 1947 through to 1954. SW342 also had a Mamba in the nose in 1952.
