    How this aircraft got to be on its back is pure supposition as already stated. The actual ditching process is influenced by so many factors, speed of touchdown being one, slow means high AoA and the rear fuselage strikes the water first and might break off, a faster touch down gives a flatter angle but more stored energy to lose and any weak point (glazed nose) is a potential scoop that could fill the fuselage with water in seconds. Dipping a wing tip in first will result in a violent rotation(again possibly breaking the tail off) which may or may not help survival, more help in the case of high winged aircraft which turn upside down if ditched straight ahead. Add to all of this the wave state, wind strength/direction, crew incapacitation, control difficulty due to damage and visibility then anything could have happened. I desperately hope that when it is eventually turned the right way up the upper surface is in a good state of preservation, fingers crssed.

    Richard, they lift them complete and then unbolt the wings, engines, tailplanes etc once out of the water, doing that underwater would be nigh on impossible. They tend to be bolted on, not riveted. The tanks will have been built to accommodate the dismantled aircraft.

    Hope that helps 🙂

    Yes I understand how the airframe can be taken apart at manufacturing breaks but that assumes the original potentially highly corroded fasteners can be removed. What I meant was to cut(saw) the airframe into manageable pieces, sacrilage I know. My reasoning is that if the airframe is in a very very delicate state breaking it into manageable sections will at least mean something worth preserving will get to the museum, whereas an attempt to lift an extremely delicate complete airframe could end up in disaster. I hope I am wrong.

    Why go to all the effort, added difficulty and expense of attempting to raise this aircraft in one whole piece when the conservation tanks look as if they are only big enough for broken down component sections?

    So when this aircraft is eventually lifted from the sea bed, which I hope is sooner than later, what will happen to it.
    Obviously it will need a thorough wash to remove as much salt water, mud and sand as is possible but much more will still be trapped inside any hollow/inaccessible parts of the structure. Corrosion will take hold rapidly once the parts are out in the air and that would be a tragedy.
    Does the aircraft need to be treated like the Mary Rose with the whole aircraft being left in a tank of fresh water or one filled with something akin to WD40 until each component can be conserved properly.
    Anyone know what the plans are?

    The way the metal is torn around the edge of the holes it makes me think the tool that made the hole was rather crude, perhaps just a steel bar or tube pressed into a block of something soft, perhaps wood.
    I also wondered if someone was making some sort of letter ident discs discs, would the letters that are still visible fit in the size of one of the punched out holes, although saying that they do look a bit big. Perhaps they used a smaller letter size for the ones they punch out.

    I usually frequent the Historic forum but I saw this thread and thought I would add my tuppence worth.
    The issue with any turbine powered replacement is engine overhaul life, measured in cycles not hours like the piston engines on the Trislander. Add to that turbine overhauls are expensive to do with costly lifed items to replace.
    What is needed is an islander with a Trislander fuselage length for the capacity and a couple of diesel engines that are able to run on Avtur!

    It would have been easy to fit suitable board room furniture into a standard Hastings cabin, held down using the cargo/seat floor attachments. Although it is difficult to see how it would have been used while the aircraft was parked on the ground due to the fuselage slope. Not a problem in the air but no one could hear then due to the engine noise!
    I dont think the four, sound proofed, VIP configered C4 Hastings WD500, WJ324/5/6 had a large table as part of the VIP conversion judging by the interior pictures I have seen.

    Found this on the Pathe site, film of Javalin’s arriving in Zambia in 1965.
    http://www.britishpathe.com/video/raf-arrive-in-zambia
    It does state (Orig. Neg.) Old record suggests that material dates from around 01/12/1965′, which does imply they are unsure of the exact date.
    Nice film of the Bevs and Hastings.

    Thats a good choice, always my favourite RCAF scheme with white wings, red horizontal stab and all that polished metal, a real work of art and a sight to behold.
    You might need a team of polishers though.

    Is this the same as what is called a crash switch, they cut electrical power in the event of a moment of high ‘G’ due to an accident but can be set off in a heavy landing, the lever would be used to re set it if it had tripped in the heavy landing instance.

    in reply to: Stirling V Lancaster. Which was better designed? #948137

    I have never understood the wing incidence issue with the Stirling.

    As it was originally designed/built the wing was set at the optimum angle for the cruise situation, offering the least drag as the fuselage remained horizontal and in line with the airflow.
    It was the long takeoff run that was seen as a problem, but why.
    For take-off the aircraft would accelerate until the elevators became effective, then the tail could be raised until the fuselage was horizontal.
    Once flying speed had been reached rotation took place following backward control movement, the tail would lower slightly, incidence would increase, lift would increase and the aircraft would leave the ground.
    Surely this would happen regardless of whether the aircraft had the original height undercarriage or the modified taller undercarriage.
    Am I missing something here?

    All 4 Super Guppies survive – but only the one above is airworthy

    Five Super Guppies were built, one went to NASA and that was retired to the Pima Museum. Another four were built for Aerospacelines/Airbus component transport, and three of these have been retired, 01 is at Bruntingthorp, 02 at Toulouse, 03 in Germany and 04 was sold to NASA to replace their first one and that is the one still in service.

    The CL44 Guppy was being worked on at Bournemouth but with the financial demise of its owner it must surely be attracting the attention of the scrapman.

    This is on EvilBay at the moment, says its taken at Brough and it looks like a Meteor NF11/12/13 being used for some sort of trials going by the long nose probe. Anyway he is pretty damn low.

    I am in no way connected to the seller.

    Updating my own post, I think this is WD686 operated by the TRE at Defford http://www.airliners.net/photo/UK—Air/Gloster-Meteor-NF11/2126028/&sid=4cc9cd77b4b22e9762a1265d33c73d27 it still survives I think in Norfolk.

    I’m surprised this a/c never ended up with The Shuttleworth collection

    Yes, I too think Old Warden would make an excellent home for the Q6, Mr Percivals beautiful wooden creations are sadly poorly represented there since the Mew and Vega Gull left. Perhaps once it is airworthy the owner could be persuaded to pop along with it.
