    As I have said before, all you really need for a round trip to Berlin, is 400 gallons of high octane fuel attached to yourself by some means of an aluminium based frame……

    With regards to the spitfire having a higher drag than it’s contemporaries, they being the BF109, the Hurricane, and the P40; are we sure about that?

    Why would the Americans waste serious effort modifying a spitfire to do a job that a home grown A/C was perfectly capable of doing?

    What about the gay one? haven’t seen much of him….. and the one named Kowalski (always one named Kowalski) and the use of the phrase “looks like we got company”

    Tony I’m not suggesting that you can, what I am saying is because modern manufacturing methods tend towards machining from solid, there are no drawings to support this method; in fact I believe to satisfy the CAA you have to show that there are no longer any servicable units available, before they agree to newly manufactured components by alternative manufacturing methods, and materials, and even then the process can take years.

    An interesting aside, I believe (from memory) that the Merlin crank can be ground, but the amount that is removeable is something like 2 or 3 thou; where do you go for that undersize bearing? I would imagine there is quite a lot of remetalling old bearings going on!

    I disagree. Look at the world of motorsport engines, limited numbers of precision engines are being built all the time. As far as no drawings…ever heard of reverse engineering? The Soviets did a good job of it with (foolishly provided) UK engines 65 years ago. (I bet the drawings of American produced Merlins are available somewhere).

    With today’s technology, anything can be reproduced, or are you really suggesting that the industry that took men to the moon is incapable of replicating 1930s technology?

    I would imagine that quite a large amount of the engine would be machined from solid, as is the norm these days; drawings for this process don’t exist as much of the original manufacturing was castings and forgings, however I don’t think that there is a need to make new Merlins just yet, as they are (relatively speaking) still plentiful, the high cost is (as ever) the man hours to assemble a very complex lump .

    As for putting a man on the moon, can you still achieve that? (given NASA’s budget cuts)

    “I hope that the lengthened version of your short story, meets with your approval”

    Indeed it does………….However, the sight was advertised as incomplete because the glass and frame head was missing, (and still is!) as was the bottom plug, these I knew about, the adjusting ring I did not, the brass ring in the box (it’s origins are unknown to me) doesn’t even fit the sight, let alone be the correct one; don’t recall being offerd a full refund, but can well imagine that I asked you if you had any Spitfire parts, (on which we could make up the difference) and basically what your saying is you didn’t have any then, and over the eight year period you haven’t had any since?

    If you want to tell the folks why I wasn’t able to get hold of you, (over the subsequent years) to ask if you had anything in yet, be my guest, personally I put it down to experience, (and the fact that I sold the empty box on ebay for £20, which helped sweeten the experience)

    Well I’m giving serious consideration to attending Damyns hall next year, anyone want to join me to make an aviation corner?(might have to be a straight) I think as an up and coming show the oportunity exists to get established.

    “Does anyone have a definitive list for all the aircraft recovered by Jim Pierce?”

    It would appear all of them, David.

    Last year at Damyns hall the Lancaster did three or four passes, at £20 entry fee for a family of four, that probably represents the best value that I know.

    There are significant differences between cockpits and military vehicles (I used to display both) much of the heavy stuff is owned by haulier types who just love trucking! and enjoy the opportunity to “plough” someone elses land! the lighter stuff (jeeps etc) are normally self propelled ; much more fun than towing a trailer several hundreds of miles, to then park it in one spot, before towing it several hundred…. well you get the idea!

    Event organisers must offer incentives if they want quality exhibits, you can get dozens of jeeps/champs they are fun to drive, and they don’t get stuck.

    You really need a 4×4 and a trailer,( which might be permanently attached to you cockpit, thus added expense) and then theres the thorny subject of insurance (try getting your cockpit insured, and you need third party to display it, even if no one can as much as touch it)

    I suspect the problems are the same for exhibiting at purely aviation events, as they are for broader military events, these being, the transport and the accomodation (for two or more days shows) Shoreham is a long where from anywhere, and an event that opens its doors early requires those attending to be there even earlier than most other events, that coupled with the fact that it would only be a one day event, with no evening attraction (for example I believe that Hendon RAFM had a forties band Saturday night).

    The Damyns hall military event had vitually zero aviation participation, as was the case last year, although in previous years there was an abundance of Spitfire replicas; I noticed too that XXX aviation prints had a large tent there.

    In my view an up and coming event with an airstrip, but if the organiser wanted cockpits and other displays, he should make that known more widely, as word of mouth via the military vehicle boys only travels so far!

    Forties events a very popular, but how many cockpits from that era are out there that can be travelled around?far more cockpits from the 50’s 60’s and 70’s but how many events cater for that era?

    Am I right in thinking that the ebay user name is almost exactly the same as his real name? if so I bought a gun sight from him about 8 years ago, when it arrived the adjusting ring was missing, and something else similar was laying in the box; it didn’t fit, and wasn’t at all the right size and shape, the seller was “surprised” to hear of this ,but that is where the matter ended, as comunication petered out.

    “Among a plethora of figures, he shows that 19 Spitfire Squadrons destroyed around 530 aircraft (at an average 28 per Squadron,) while Hurricane Squadrons destroyed 656 (at 22.5 per Squadron.) So the Hurricane destroyed more in total, but fewer per Squadron.
    If nothing else, it shows that the old saying that “There are lies, damned lies, and statistics” still holds good”.

    The facts here are undeniable, and yet there are still those (in perhaps a form of inverse snobbery) that want to show the Hurricane was better at the job; debate after debate has raged trying to show that the Hurricane was better to land a more stable gun platform, less prone to overheating on the ground, easier to repair battle damage, and on an on, an yet the official figures are beyond dispute.

    “on another track can people list who they think can add up to 140 years expeariance I mean it would take 10 people with 14 years each with hands on so to speak”

    Well Bob Cunningham has about 70 on his own!

    Perhaps this is a new venture by “Spitfire4hire”, I haven’t seen an update from them in a while……

    Right, so now I’m a Nazi for trying to bring some order to the proceedings? Come on, credit me with some intelligence. Lets stick to the topic please…..

    Chill Bruce, where’s Mel Brooks when you need him?

    I don’t believe the use of the word ‘nazi’ is appropriate to describe anybody. It conjures up a lot of nasty images.

    I have thus removed a comment above, and deleted some other responses to it.

    Bruce

    So you deleted my response, to add your own which is essentially the same wording….

    Isn’t that the sort of thing the Nazi’s might have done?
