    Whitley_Project I would say a salt water recovery is still worth it depending on condition and what you want to do with it afterwards – there will always be some useable parts as probably the basis of an identity.

    Don’t forget, there are still many extinct types – marine recovery followed by difficult and expensive conservation is the only option for many of them.

    Elliott, I do agree

    With 60 years now being the period of salt immersion of these dumpings and other wrecks, I think the salt water recovery days of WW2 a/c iare coming to end, unless you are desperate for patterns to recreate an extinct type such as the Skua or Devastator.

    There have been some exceptions to the rule, the P40L recovered from the beach in Italy appears to be in surprisingly stable condition, and was obviously well worth the effort of recovery and saved an extinct sub-type, without even the need to use it as patterns?

    The current project to recover and preserve a Sunderland mark I is a good case study to see how much will really survive the recovery?

    The holy grail of a complete Stirling being recovered and restored will probably justify the effort of still looking and hoping.

    But the recent recovery condition of the Skua shows that these materials are deteriorating over time, and for most of the dumped/ditched or wrecked aircraft the clock must be at the proverbial 5 minutes to midnight?

    In regards to the Corsairs etc dumped off Australia, workshops seem to be solving the process of “recreating” rare parts such as wing centre-section spars etc, and already have enough patterns without fishing out more, in very poor condition, and I dont think many of these dumped parts are suitable for re-use.

    In regards to fishing out a wreck for its identity, I do think we need to think through this habit of finding a corroded rivet, assigning an identity to it, throwing it in the scrap bin, dragging out a replacement and claiming we are now restoring the original complete aircraft. The Corsair cockpit in the photo’s above would seem to yield little other than a shadow on the workshop floor.

    If we use jigs and patterns from other restorations we could “rebuild” it in 2008 metal, but then have we really “restored” it, or have we “recreated” it.

    If we can do that from existing jigs and patterns and use of other spare parts, why fool our selves and posterity by recovering the wreck to claim its identity?

    I much prefer acknowledging the “receation” for what it is, like the F#F, ME262, Oscar and FW190 limited productions of recent times.

    I do support trying to recover the Devastator in the Marshall Islands before there is nothing left, and trying to stabilise and preserve as much as possible.

    And if its possible to “restore” and fabricate a complete example even better.

    In Australia we have a number of the GAF built Australian Canberra’s surviving as well as 2 surviving former RAAF “British” built trainer Canberras imported to support the RAAF operations of the Australian built aircraft, and 3 surviving former RAF U-10 British Built Canberra’s from use at Woomera.

    One of those imported british built RAAF Canberra’s is A84-307, the former WD939, s/n 71020. It is listed on the Australian ADF-Serials.com site as being “The world’s oldest surviving Canberra” jet?

    By RAF identity, it seems to the oldest complete airframe existing after the cockpits of VX185, WD931 & WD935? (I’m not a RAF ID expert but I assume in this case alphabetical = chronological?)

    Anyone able to confirm if it is the oldest complete canberra survivor, and what number in the production line from the prototype was it?

    This nicely preserved Canberra began its life as a B.2, WD939. Awaiting collection in August 1951, it was immediately delivered, on 1 August that year, to the Royal Australian Air Force. Delivery was over a four day period from RAF Lyneham to Darwin with the Australian crew, Wg Cdr D.R.Cuming and Flt Lt Harvey, setting up an unofficial fastest jet record for the trip, flying 10,200 miles in just 21 hours. WD939, all-over silver with a black fin, arrived on 5 August 1951. For a few days it flew out of Laverton to assist training and aircrew conversion before it joined the RAAF’s 6 Sqd as A84-307.

    In 1958, it was converted to a Mk 21, first flying in that configuration on 29 September of that year. As a Mk21 it was delivered to 1 Sqd in the November. Later, a stay with the famous 2 Sqd was broken when A84-307 transferred to the RAAF’s 1(B)OCU. It ended its service life on 2 Sqd and is currently in a park area of the Defence Munitions Depot, Kingswood NSW Australia. Bob says that because of the sensitive nature of the area, it took him some time to get approval to take the photos.

    It has recently joined the National Vietnam Veterans Museum in Victoria.

    OP mentioned that some, according to legend, might still be in packing crates (maybe not aircraft, but engines and other parts).

    Does anyone have another take on that story?

    I would belive it possible, but very unlikely. We all know that tons of stuff was discarded after the war, but there were also quite a few surplus sales.

    The material dumped off Australia is understood primarily to be RN FAA aircraft (and perhaps obviously some RNZAF? types that may have been intended to operate with the RN FAA in the Pacific?) lendlease material, which is “lost during the war” did not have to be returned?

    There are photos of the aircraft stored on shore in Australia before being dumped, they were primarily complete aircraft but there may also have been NOS airframe and engine spares dumped in the same process.

    Rumours have suggested P40’s, P51’s and Spitfires in boxes sitting in the same dumps, but there does not seem to be any substance of unaccounted airframes in the RAAF inventory that would line up with those types being included in the dumping. The photo’s I have seen were all US and UK built Carrier types, I assume the UK examples may have simply been dumped as a downsizing of the RN inventory, rather than lendlease payment related?

    In anycase, anything in wooden boxes is likely to be as salt impregnated as all the other airframes, and of questionable recovery value.

    With 60 years now being the period of salt immersion of these dumpings and other wrecks, I think the salt water recovery days of WW2 a/c iare coming to end, unless you are desperate for patterns to recreate an extinct type such as the Skua or Devastator.

    There have been successful salt water recoveries and preservation for ongoing static display, but I am not sure future recoveries will yield structures capable of stabilisation for static display, let alone airworthy restoration?

    .
    The Lincoln was originally developed in 1943 as the Lancaster “IV & V”, it was simply a Lancaster with an improved wing design (greater span) and lengthened fuselage to provide greater range and payload, the prototype first flew in June 1944 and the type entered service in August 1945.

    In 1944 the Lancaster marks I, II, III and X were deemed to be doing the job so there was no rush to switch production over to the Lincoln for the European theatre with the complications of conversion training and spares, but numbers were being built up in 1945 for the Pacific RAF campaign against the Japanese in what was known as Tiger Force, but the Lincoln’s greater range was still far short of that being delivered by the B29, and the nuclear capability of the B-29 brought that need to an end.

    The RAF had proposed in-flight re-fuelling for the Lincoln in the Pacific to achiever the island hopping ranges the US was achieving with the B-29 and there was resistance by MacArthur in regards to that situation.

    The Lincoln did not have the speed or high altitude performance of the B-29/B-50 and therefore was not a suitable post war bombing platform for Nuclear weapons, a Griffon engined example may have created the speed, and the Lincoln was fitted with many other more exotic engines for trials, but the Lincoln was not pressurised, and it seems likely by that time Britain was developing jet bomber solutions such as the Canberra and other Jet Bombers, and further development of the Lincoln was not warranted.

    The Shackleton was a post war development from the Lincoln for a specific maritime role rather than as a bomber replacement, it benefited from the hindsight of design, and access to the current technologies, and was developed with a new pressurised fuselage, Griffons and contra-rotating props.

    Although interestingly these features were not really ever used operationally to deliver significant extra speed or high altitude or nuclear stand-off capability in that maritime role they were the natural improvements the Lancaster/Lincoln design required to achieve B-29/50 performance.

    The First flight for the Shackleton was in March 1949 with production deliveries commencing in 1951, some 5 years after the equivalent dates for the Lincoln, and 8 years after the equivalent dates for the Lancaster so plently of room for hindsight and improvements.

    Peter,

    The Lincoln parts that have arrived so far have been cleaned and sorted and are in temporary storage onsite at the museum while long term undercover storage is being developed.

    Existing parts in Australia are starting to be identified and gathered, with a top turret plexiglass, and tail leg assembly recently on offer.

    The rear fuselage tailplanes, fins and rudders, main wheels, centre-section trailing edges and other misc parts are yet to arrive, (the transport arrangements from London to Melbourne included a stopover at a transist location, and those parts are still located there at this point in time).

    At this stage the Museum’s immediate plans are to place it into undercover storage and continue to collect remaining parts, it will be a very long term project.

    At least one Corsair cockpit/centre-section was recovered, and immediately started to convert to aluminium oxide, it was on public viewing in a residential yard in Queensland for a while and then rumoured to have been sent to the US for parts recovery.

    I suspect the poor condition of that recovery dampened the enthusiasm to continue with any others?

    Nothing to do with Fairy IIIFs but while browsing Google earth I spotted what appears to be a fuselage on Kilimanjaro ,its not the DC-3 that crashedand appears to be about 60ft long.Co-ordinates are 3deg 05.20 south and 37deg 22.53 east.Anyone know what this is?

    WL745,

    could you check your google earth co-ordinates? I looked at 3deg 5.20’S / 37 deg 22.53″E as well as 3deg 5’20″S / 37 deg 22’53″E and could not find any suspicious 60′ long objects?

    the google image attached is from Kilimanjaro at both those co-ords with a marker line of 60′ in white, this is near the “Kibo Camp” blue dot marked by GE is this the location you are referring to?

    No Stuart it is’nt the source, it was however a starting or reference point along with the original post/photo with the engine plaque inscription.

    I have been corresponding with a number of newspaper archives and library archives in the UK on this since the photos were posted as artifacts from such early aviation interests me, and the info above is from those sources seperately confirming Howcraft Carriage Company (and their address) as the builders, but also providing the additional details of the date, designer and pilot’s name, cost of the aircraft etc, I am currently awaiting the full research material of newpaper clippings of the time via mail to turn up, the info above is a summary of what has been found so far, but still no allusive aircraft photo etc.

    Scott?

    Any more information available at the museum on the engine or aircraft it was fitted to?

    My research has identified the aircraft was built by Howcraft Carriage Company of Oxford Road West Hartlepool at a cost of £200.00.
    The aircraft was designed by a Captain Joseph Donovan and on the day of the scheduled flight it was he who attempted to fly the aircraft.

    The attempted flight occured in late October 1909, thereby an important attempt at rivalling S F Cody for first to fly in the UK?

    mark_pilkington
    Participant

    Scion probably has the highest concentration of pobjoys in Australia, and those have largely remained together with their respective aircraft projects, there are not a lot of others floating around and I am aware of a vintage aircraft rebuilder in South Africa who has been seeking an engine for a number of years.

    There is a Pobjoy on display in the engine collection of the Australian National Aviation Museum at Moorabbin, this is associated with the BA Swallow under long term airworthy restoration in the collection, although it is unlikely to fly with the Pobjoy given that engine’s rarity and lack of spares.

    I am only aware of one other museum preserved pobjoy in Australia, and am not aware of any others that are not part of flying projects, although Scion may know of others stored or available?

    However I dont think acquisition of a pobjoy, and the required operational spares, is a project I would like to embark on, and I certainly wouldnt choose a replica project to be powered by one.

    I personally would still choose the Rotec, with the additional power being some compensation for its additional weight, but taking advantage of the newly available engine and its resultant spares etc, as against the uncertain ability and cost to acquire a Pobjoy and make it airworthy and support it in operational spares.

    (btw – no , the Moorabbin Pobjoy is not for sale – smiles)

    in reply to: Supermarine Spiteful, what are the possibilities #1227330
    mark_pilkington

    Hi Cees

    This is an interesting point that you have raised.

    Just sticking to the remit of the RAFM at Hendon for a moment, and their wish to display as many examples of types operated by the RAF, then there are several notable ones absent.

    Just off the top of my head here are some 40’s era types:

    Extinct:
    Supermarine Spiteful
    Westland Welkin
    Westland Whirlwind
    Bristol Buckmaster
    Bristol Buckingham
    Vickers Wellesley
    Short Stirling

    Partially extinct:
    DH Hornet
    Bristol Brigand

    The trouble is many of these now extinct types were few in number in the first case, and many did not see combat use. This second point really drives the desireability of recreating a type from scratch. A post war type with little or no combat use ends up an interesting footnote in history, with little money to realise a professional recreation.

    Your idea of recreating a Supermarine Spiteful is a sound one based on some of the common parts that could be gleamed from the spitfire industry, and the wing of the Supermarine Attacker could be measured in detail, but the desire and money to do it would have to be considerable. If they really wanted to do this I suggest they could sell or trade one of their spare (stored) spitfires to raise the funds, but I cannot see this happening at the moment. To be honest, they could do exactly the same to raise funds to restore the Halifax properly instead. I bet you’d support this more! 🙂

    smiles “partially extinct” is that like being 1/2 pregnant?
    (sorry David – I just found that amusing)

    I think the issue of National Collections “recreating” or “reproducing” airframes should be limited to airframes or types of significance, and not simply to create a “missing” type in a series etc for enthusiasts like a model plane collection.

    I am not in a position to speak authoritively on the significance of the Spiteful in English Aviation Heritage but I would have thought there would be far higher priorities of “missing” types in the RAF Museum collection or even distributed National Collection than the Spiteful? and in that way I would agree with David Burke.

    Even the work David Collins is doing to create a DH Hornet “Reproduction” is probably outside the focus of the RAF Museum as a type of importance to them, (not in any way undermining my appreciation for what David is trying to do), ie would they ever commence the project David has undertaken?

    Where a “partially extinct” (smiles) type such as the Hornet or Skua can allow a composite or “recreated” example to be created from original sourced parts and patterns, that effort should either derive from the types significance to a collection (and their ability to undertake it) or be left to those enthusiasts who are willing to take on the “impossible” driven by their own interest/obsession in the type and capability to do so. (Glynn Powell’s Mosquitos probably fit into the same mould – if you pardon my pun – smiles)

    In the end a “recreated” Spiteful may not provide much more benefit to the RAF Museum than a Full Scale mockup would? and would consume far more funds and effort, for the same external display outcome?

    Perhaps like the replica MB6 in the USA, the Spiteful will attract a warbird investor to fund a flying “recreation”? but again thats likely to be driven by a personal interest or obsession, and lots of disposable income.

    It would seem a close approximate might be created from a P51 Wing and a new build fuselage started with the Spitfire fuselage frame kits that seem now readily available?, and capable of being registered and operated in the US in the Experimental category?

    I think David Collins hits it on the head in his comment above

    “This second point really drives the desireability of recreating a type from scratch. A post war type with little or no combat use ends up an interesting footnote in history, with little money to realise a professional recreation.”

    In the end a composite “Spiteful” may not really be an accurate “Spiteful”, so if not intended to fly, why not simply produce an accurate fibreglass FSM at much lower cost and effort? or why not leave it as a type to dwell in photos and books?

    I personally would prefer to see a sympathic restoration of the Halifax proceed over such a Spiteful “recreation” outcome, or a “Recreation” of more historically important types such as a Stirling (fuselage?) or the current Hampton projects.

    A case in point is the Halifax composite recreation “Friday the 13th” at Yorkshire, an excellent project undertaken by those enthusiasts, but perhaps a project that the IWM or RAFM would never have contemplated having a role or place in their own collections?

    Is it really an authentic/accurate Halifax perhaps not, and in its case does it really matter?
    (again not intending to diminish appreciation of what has been achieved)

    That project has delivered a full size complete “Halifax” on display for educational and experience values, even if not perfect for historical and technical research purposes.

    The Halifax is a very important type in aviation history, and at the time it was an extinct type. In fact in part it continues to fill a gap left by the non-restoration of the RAF Museum’s example, perhaps lessening the likelihood of that airframe being “restored” rather than “conserved”, as a restored “FSM” can be viewed elsewhere?

    In Australia one day I am sure someone will seek to place a “CA-15” on static display, should that be a frame, skin and rivet “reproduction”, or simply an externally accurate FSM?

    I personally will be more than satisfied to see the latter.

    Yep thats the one, AJD imported it, took the engine and sold on the project.

    Guess that shows the rarity of Scarabs in the UK, having to import an aircraft just for its engine??

    I suppose the Fairchild F24W Argus were the most common Scarab engines ever brought to the UK?

    They were a little more common here in Australia due to the 200 CAC Wackett Trainers built and other spare engines to support them, but very difficult to find one in Australia now days too.
