    Did somebody mention Slough?

    I’ve been to Slough – how did they miss it?

    Yep, BeauFREIGHTER

    Ja/JDK

    That’s correct – I was referring to the converted Beafort with the high rear fuselage and faired over turret opening. I think I’ve only ever seen one photo and a vacuum formed plastic kit a few years ago – until I saw the kit, I’d never heard of the ‘freighter. Was it an Australian development or British?

    After reading your post, I consulted Armed and Ready, a reference book I have found invaluable with questions such as this.

    Owing to the difficulty in getting the necessary components from Britain under wartime conditions, the APC was forced to seek many parts from the USA, which led to problems due to the differing manufacturing techniques between the UK and the USA.

    During its early experience with the Beaufort, the RAAF found that it had a tendency to yaw and roll, which Bristol knew about but had failed to properly address. Australian experience found that by increasing fin and rudder area by 15.5%, the problem was fixed. This information was made available to Bristol in late 1941 and the subsequent British built aircraft were so rectified.

    Other problems with the Beaufort arose because it was a cold-climate aircraft and this was addressed during Aussie manufacture. As well as this, other problems needed to be addressed and a total of 1606 parts were modified for Australian use. Some of these changes were to address design inadequacies for Australian use, whilst some were simply Australian manufacturers developing their own techniques for local manufacture.

    To quote A.T. Ross, author of Armed and Ready:

    “The result of all this was that the Australian Beaufort was not a faithful copy of the British aircraft as originally expected in early 1939. They were significantly different and were in fact probably superior to the British model because, amongst other things, the Twin Row Wasp gave them more power.”

    Ja, hope this info is part of what you were looking for.

    Don’t get me started about the Australian Cruiser Tanks – wrong forum, but another lost opportunity for Australian manufacture stuffed up by idiots!

    Regarding the Wilson Books, I entered the Aerospace Publications website and noticed that the Beaufort/Beaufighter book is no longer available. Damn, thats the one I wanted.

    I’d like nothing more than to see a CA-15 (not Kangaroo, that name was never official) AND a Woomera fly side by side – wonder if they ever did? They sure would make good restoration projects.

    How about the following aircraft in a fly-off to see which one was the superior performer?

    CA-15
    MB-5
    Spiteful
    P-71 Eagle

    All aircraft were too late to be developed and each resembled the epitome of piston engined fighter development. Can anybody suggest some that I’ve missed, that never reached production (although I think some Spitefuls entered service, not sure)

    Ron

    Regarding the similarity of the two aircraft, I remember reading years ago that the CA-15 was just an Australianised modification of the P-51. When I first saw the photos of it, I could understand how that conclusion was reached. Does anyone know whether there are any photos of the two together – surely they must have stood side by side at the factory sometime during 1946 or early 47?

    I agree that Wackett would not have wanted to dwell on failure, but it struck me as odd that he simply didn’t mention the bomber at all during his book – it just has the entry of “Bomber prototype – 2” in a small listing of WWII production output. The Boomer and the CA-15 did get some mention. The other point to remember is that a book such as his would generally only appeal to aviation afficionados, who would be interested in technical detail, as against the general public, so I would have thought that his views would have been worth airing. I certainly would have loved to read of his views of the aircraft, its development and its eventual fate.

    Re Cotton books – I only know of one – “Last Plane out of Berlin”, which I read recently. Obviously, it was about him, not written by him, and I don’t know whether he wrote any of his own stuff.

    LPOOB is an odd mixture – interesting in its content, but somewhat mixed up in terms of chronology. It seems to jump from one stage in Cotton’s life to another, then back, then forward again. Little difficult to follow, but an absorbing read about a fascinating man.

    Whilst on the subject of books dealing with Australian aviation, do you and the other members who have joined this post collect as much literature as possible about the subject?

    I have only collected three or four of Wilson’s books to date, and intend to get the Beafort/Beaufighter book as soon as I find out the printer’s new address. They used to be at Weston, ACT, but I believe they have moved. Does anybody know the new address and can you recommend any other books by Wilson in the series of RAAF service?

    I also have another subject dear to my heart about CAC and you would need to have Wilson’s book on the Wirraway/Boomer/15 to know what I am referring to.

    How did the CA-15 end up looking so much like the P-51 when it started out looking so unique? If you look at the early R-2800 version drawings and plans in Wilson’s book, the aircraft looks like nothing else, but with the replacement of the radial with the Griffon, the resemblance to the ’51 is amazing, particularly when you look at the wing plan, tail empennage design and radiator intake. I think that the early design took place prior to CAC taking up the ’51 license for production and it is difficult to see how they could have designed the main plane to be so similar in shape, especially when you think that the “51 planform was so distinctive.

    Any ideas?

    I would have thought that Wackett would have been more detailed at least in describing CAC’s achievements during its formative years. Whilst the Woomera was not a success, it was a huge undertaking for such a young company and was designed to meet very stringent, and overly ambitious, specifications – in short, it tried to be too many things in one. Did anybody else, with less than three years manufacturing experience, attempt to build a twin engined aircraft as their first truly indigenous attempt, which was a dive, torpedo and level bomber, armed with four machine guns for the pilot, four remotely controlled for another crew member, with a longer range than many of its contemporaries?

    The Woomera wasn’t the most attractive bomber but to look at it, the intent is obvious – to me, it had the potential to be a potent weapon.

    If Wilson does manage to get enough information together, it will be a fascinating volume. Between him and Meggs, one would have to hope that a detailed and overdue history will evolve.

    This could be risky but…

    Re the FW 189 – I could have the wrong aircraft, but I think you can access its progess on its own website through links within the “other” magazine’s website…

    I reckon the Meggs books would be worth whatever he asks – I certainly would be prepared to save hard to get them, whatever the cost. I’m frankly amazed that there are enough Australian designed aircraft to justify four separate volumes. I can think of only a few, apart from the very early efforts from Wackett and others pre CAC, such as the Widgeon I and II. More modern efforts I can think of include the Nomad, Victa Airtourer, the weird looking skytruck thingo currently being made and the Spitfire replica, but that’s about it.

    Ja

    The libraries around here don’t cater much for us aircraft loonies – the few books they do have are more general on aircraft and they don’t carry aero mags at all. Still, I’ll keep looking.

    I must say that I am enjoying this Aussie discussion group – there are plenty of us in the forum, but unfortunately, our aero industry hasn’t given us all that much to talk about. (and I really AM sick of reading about all that Pommie and Yank stuff!!!! – we need some variety.)

    One thing that just struck me comes from reading Wackett’s autobiography, “Aircraft Pioneer”. Whilst he goes into a lot of detail in the book about the selection process for the Wirraway and the Mustang, his writings on the development of indigenous aircraft is extremely brief which I think is a terrible shame. For example, re the Boomerang, a brief tale relating to its genesis takes less than two pages. The Woomera is a mystery – the only reference I can find in the whole book is a photo of Wackett and other CAC executives standing beneath the nose of the CA-4, and a reference to 2 bomber prototypes in a list of world war two production totals. Absolutely no text about this aircraft which must have been extremely significant to the company in its early years! The CA-15 also only gets a very brief mention but scores that well known profile shot on the tarmac amongst the photos.

    I wonder why Wackett didn’t go into more detail in the development of those three aircraft – the Wirraway gets a very solid coverage.

    Thanks

    Thanks chaps – (Hi Ja!)

    It’s nice to get your responses to my post, as it’s a sad but true fact that the achievements of CAC don’t get much of a mention on this forum, limited as they were. (How many aircraft manufacturers built 250 “fighters” in the middle of a war, none of which ever shot down an enemy fighter?) Notwithstanding that, I’m personally proud of what CAC did achieve and really regret that the Woomera and CA-15 never progressed to mass production – I’m sure that both aircraft could have been up there with the best in their respective classes if their development hadn’t taken so long.

    On the subject of books etc about the Woomera, perhaps one day those articles you mentioned may come my way – I can only hope, but I have wondered for some time why Stuart Wilson didn’t include the Woomera in his excellent series on aircraft in RAAF service. After all, the CA-15 only numbered one in total, yet Wilson was able to supply an enormous amount of detail about it in his book alongside the Wirraway and Boomerang.

    When you consider the large number of photos and drawings that exist about the Woomera, plus the fact that two were built and the second one was trialled by the RAAF for some time and not broken up until around 1946, you would think that there was enough material available for Wilson to have covered the aircraft when preparing one of the other volumes.

    I must also admit one other reason for posting this thread (and I have no wish to offend any member of the forum in stating this) :diablo: but I am sick to death of posts about Spitfires, Mustangs, Hurricanes and a host of other famous aircraft that predominate here. It gets boring and my parochialism drives me to try to bring just a bit of variety to the forum.

    If I have upset anyone….

    stiff!!

    Yep, you’re right

    Hi Ozmatt,

    If I’d bothered to get off me blot and check my books, I would have got the model number right first time – thanks for the correction.

    You mentioned Keith Meggs’ book once before some months ago. What can you tell me about it? At the time you mentioned it, I was reading Wirraway to Hornet, and thought that Meggs’ book(s) sounded like something I had to get, but on the New South Wales Central Coast, specialist book suppliers are non-existent. Do you have any idea of who the publisher will be?

    One thing that has always fascinated me about CAC was that, shortly after commencing production of the Wirraway, they launched into the development of something as complex as the Woomera. The company had barely been in existence for more than about 3 years!

    After reading my two available references on the aircraft, one can’t help regretting that Wackett tried to be too clever with the aircraft. If he had agreed to fit conventional fuel tanks, instead of trying to seal the inside of the wing structure to act as tanks, and had given away the remote controlled barbettes on the nacelles, the aircraft might have had a real chance of mass production. Off the top of my head, I can’t even think of a major aircraft manufacturer that tried remote controlled nacelle mounted barbettes up to that time. The Woomera might not have been the most glamourous looking bomber of the war, but when you take a long look at the few photos available, the potential is obvious.

    It really p******s me off

    I guess I’m one of those .01% who notice when things are wrong, and there has always been one trend in war films which really gives me the tomt…s.

    That is where a dogfight scene, or an aircraft involved in a strafing scene, changes from one type to another, particularly during close-ups. I have lost count of the number of times I have seen Captain Clod pouring lead into a Zero or 109, and he changes his plane from a P-51, to a Spit, to a close-up of a P-47 (the scene with the six .50’s protruding from the wing, with the inner gun protruding slightly further than the centre one, and the outer one further recessed into the wing – I’m sure we’ve all seen that shot. Then, just to get more mileage out of the same scene, it’s played in the obverse, so the aircraft is flying in the opposite direction.

    To me, this is just sloppy and displays a total lack of concern for the accuracy of the film. Surely the enthusiasts amongst us number in the many thousands, and form a not insignificant proportion of movie goers. If Cameron could get his weaponry so right for Saving Private Ryan, it is disappointing to think that his doco on the Bismark was so poor. (I haven’t seen it, as I don’t have cable tv, and many of the doco’s shown in the UK don’t seem to get an airing out here.

    Hi Setter

    I agree with you that the P-40 had a pretty important and almost illustrious role to play with the RAAF in the SW Pacific and North Africa, but my point was that it was a “second-rate” fighter for almost its entire service life. Allison “power” limited its capabilities, as Allisons did to nearly every thing they were fitted to, but the P-40’s basic airframe was very old technology by 1942/43, being based on the P-36 as it was, and I wonder why they bothered re-engineering it to take the Merlin.

    Even the P-40Q, which was almost an entire re-design, could not overcome the basic faults of the original design and it lagged behind more modern aircraft.

    The P-40 was a very solid, well-sorted and reliable aircraft. It provided a sound gun platform and could absorb substantial punishment.

    It just didn’t have the aerodynamics to match later aircraft, nor did the design possess the ability to be developed in the way that the Spitfire, Mustang and many other more successful aircraft could.

    That said, it is wonderful to see so many of them being restored and taking to the skies.

    Regards

    Why did they bother?

    I knew that there were Merlin powered P-40’s produced, but have often wondered why?

    Given that they were only a second rate fighter for much of their existence, why did they bother developing a Merlin version? I know that the performance would have been superior to the Allison versions, but it was still quite inferior to other front line aircraft in the UK and the States.

    So, why were P-40’s developed with Merlins? And whose idea was it, the British or the Americans?

    Thanks for clearing up the timing of the RAAF’s involvement in this matter. The point I made could still be correct, regarding the Hudson being the first allied aircraft to take on the Japs. I know that a couple of P40’s got into the air during Pearl Harbour (heavens, if they hadn’t, how could the movie have been made?), but it would take a close examination of the times of each event to determine which aircraft (Hudson or P40), actually opened fire first.

    Of course, the RAF? Catalina shot down earlier might have put a few shots up, which would have made it the first. The most significant thing is really that the war in the Pacific started some hours earlier than Pearl Harbour and this point is often overlooked in WW II history.
