    Looks like it will be a good meeting then! Geedee and I will be coming up in my Lotus Elise replacement – a white cabrio smart car with roundels- no missing us!!!

    I will be bringing some photos if any one is interested.
    The walk to Hannants and restaurant could be good for lunch victuals.

    I thought the BoB Hall opened at 10am too? Anyway that RAFM ‘restaurant’ should be open then too.

    I will get Geedee to bring his tripod for a group photo near something vaguely aviation. 🙂

    You mean you can get two people in one of those ?

    It was also known as the Martin murderer, I would add that many of its problems with engine failures were exacerbated, because the engine feathering system was electrically powered, and that ground crews with little experience on type used to drain the batteries during mantainance,(unintentionally) causing there to be insufficient power on take off to feather a failed engine; they were reputed not to be able to fly on one engine (on take off), however I have read accounts that contradict this.

    It is possible that its high survival rate is a combination of a strong airframe, and the fact that the crews didn’t think it was capable of defending itself, unlike the early days of the B17, and flew it accordingly.

    Did I sense a veiled criticism of the recovery group by the accident investigator? He seemed to imply there was no way of knowing where on the crash site previously recovered debris had come from?

    Roger Smith.

    He might just have been using that as mitigation for any inaccuracies in his deliberance; as 682al has said you would have thought that a dive at speed sufficient to tear the wing tips off, would have resulted in a higher impact speed, not consistent with the condition of the recovered engines.

    Could it have been that in the process of recovering from a high speed dive, on levelling out, the load on the wing tips was sufficient to tear them off, at which point the A/C crashed, at a more horizontal angle, and a much reduced velocity?

    Perhaps its just me , but I thought the cause of the accident was “determined” as being pilot disorientation, but earlier on in the program,the investigator said that at least 1 engine wasn’t under power at the point of impact, that and the fact that there was a steady deviation to port from the flight plan, could that not point to something mechanical , like 1 or more engine failures?

    I know what your thinking, “did he fire 5 or 6 shots?”, the question you gotta ask yourself, is “do you feel lucky?”, well do ya punk?

    Mark.

    The Armed Forces Memorial has a searchable database which gives the names. It appears however that you do have to provide a surname.

    I haven’t looked into it but it is to Honour those who served during Britain’s period of atomic testing. I assumed that it was also intended to be a Memorial to those who had died since serving during the tests. Haven’t or aren’t a significant number of service personnel serving during this testing developed or are developing cancers which may or may not be related to the tests?

    Regards,

    By placing the memorial there, it could be viewed as an acceptance of responsibility for such.

    The reason tyres are filled with gas is that when load is applied (ie. landing) the gas will compress thus absorbing some of the shock. If the tyre was filled with water you would simply pressurise the liquid, making it act like hydraulic fluid and blow the tyre apart.

    Although not if the A/C was flying at altitude, as the contents of the tyre would be,… ice!!

    I believe the Buccaneer was originally designed to be capable of delivering a nuclear strike, (probably not in the low level role) and so can’t be seen as purely designed for low level; when it was re engined because of short comings in performance, it wasn’t suggested that there were short comings
    in the original design, just that engine design had moved on.

    If the swift had reverted to the 2 gun configuration,(and optimum wing shape) and was fitted with underwing missiles/stores (it had been tested up to .95 mach with combinations, with little reported affect to handling),together with a more reliable engine and reheat system, it would have been as good an A/C as the Lightning or the Hunter, (bearing in mind that the roles for these A/C changed as frequently as the RAF “top brass” meetings were held).

    The RAF was spoilt for choice in the 1950’s, and there was always going to be winners and losers; look at the Vampire /Meteor competition, both first generation jets both competing for the same job, but ultimately finding their own role within the RAF.

    What low-level roles?

    The aircraft (with the Hunter) was conceived and developed as an interceptor, which at the time meant get quickly to high altitude where the ‘Bears’ played, dodge the radar-laid guns, deal with any fighter escort and shoot the bombers down. Swift could do none of the above. The tactical recon role was assigned because the Swift was there and vaguely suitable. It was soon replaced by PR versions of the Hunter which would have been developed anyway. Swifts may have won ‘Royal Flush’ but most agreed that RF was pretty useless as an indication of ability in the field.

    TAC R is a fairly narrow role for an aircraft that cost the taxpayer rather a lot and was ‘super priority’ as an interceptor. There was no suggestion of developing the Swift for strike or ground attack which Buccaneers and Hunters later excelled at.

    Swift FRs were an attempt to make the best of a bad job, which to be fair was what was achieved.

    The 535 looked good in ‘The Sound Barrier’ though.

    And yet everybody says what a wonderful A/C the Buccanneer was in the low level/high speed role; possibly the Falklands conflict, and Desert Storm, have shown a need (if only in the eyes of the RAF top brass), for that very type of A/C.

    The Swift suffers from the DH Comet syndrome, it was a first, and it had faults, (some of those brought about by the RAF top brass rewriting spec whilst the A/C was being developed) and all the Comets crashed because of square windows……

    Inadequate mainplane in the punishing low level role.

    Halton late 1950’s.

    I’d say the U/C might have benefitted from some strengthening as well…..

    Just a footnote to the Swift/Avon discussion ,which has probably been running longer than the play “mousetrap”

    The root of the problem (pun not intentional) was thought to lie in the design of the intake duct, it was discovered that one of the manufacturing sub contractors had introduced a “seemingly trivial” modification in the way that the blades were machined, all affected engines were from the same (un named) manufacturer; I would have thought that the problem with the re-heat on the 105 had to be an engine problem, which, as no other A/C used the 105, was never fully investigated/resolved.

    Well if all Sheppards want to replace it is a Harrier surely, of anyone, RAFM or IWM could source one, or is that being too simplistic??

    Wamwig

    Please see my above post, they don’t want a Harrier; or it would seem the money.

    Apparently Sheppards are willing to swap the swift for a Harrier? (plenty of old GR3’s and Sea harriers about?).

    Or has this been gone over as i would have thought somewhere would want it even if it was not greatly successful it is a piece of aviation history and i would have thought that the RAFM’s collecting policy would say they should have one for the sake of it at least?

    Probably about 10 years ago they did; I tried in 2002, and they didn’t!
