the first people to make one that actually worked were in Birmingham in 1940.

You’ll need to qualify that, otherwise it’ll be claimed you mean Birmingham, Alabama.

You should pull your head out of wherever you hide it and get your facts straight..

It’s under my hair, unlike yours, which is under a dunce’s cap.

1942 Dr. Anselm Franz develops the axial-flow turbojet, Junkers Jumo 004, used in the Messerschmitt Me 262, the world’s first operational jet fighter.
Ever heard about Anselm Franz and Dr Herbert Wagner dude ?? I don’t think so..

Which is the same time that an axial-flow engine was flying in the U.K; do have the courtesy of reading what others write, dude.

The fact is and this is shared by the worlds scientific community that Frank Whittle didn’t invent the jet engine, he simply built the first British jet engine.
The jet engine or the Gas Turbine as a principle has existed long before him .

Very true, and not denied by any U.K. researcher worthy of the name; the first person to put the idea forward to this government was Mr. F.W. Meredith (ever heard of him? You should, since you “borrowed” his expertise for use in the Mustang’s radiator.)
I noticed, with considerable amusement, how you concentrated on the F-86’s engine, in Korea, and omitted to mention the F-80, which was powered by a direct copy of the centrifugal compressor-powered engine donated, by us, to the U.S. during WW2. If you can find time, while looking down from your lofty perch on us lesser mortals, perhaps you can tell us how long the T-33 (2-seat trainer conversion of the F-80,) powered by the same “obsolete” engine, remained in service with the U.S.A.F? Even the Thunderbirds used one.

Did it ever occur to you they might have done this to settle an old score for Klaus Fuchs, British citizen at that time ,selling Manhattan Project secrets to Soviets?

I somehow doubt it, since Fuchs also spied, for the Americans, on the British, and the Manhatten Project was entirely under the control of the U.S., so who was it trusted him enough (and therefore didn’t carry out properly stringent tests) to give him those secrets?
I note, too, in your usual “cherry-picking” mode, you omit to mention that Fuch’s contact was an American citizen, Harry Gold, and it was the incompetent British Secret Service who finally unmasked him.

The fact is that Nazi Germany in 1930’s and 1940’s was miles ahead of Britain in almost every field of science engineering and technology .

We’re quite happy to give them best, when it comes to gassing civilians, since we preferred to keep ours alive.

I hate the thought of a good man bending over backwards in order to take his medecine!!

Now, I realise that Jim’s had his body pulled about, a bit, but, come on, surely they didn’t twist things around that much?

Radar: You didn’t hand over the radar to Americans mate as a matter of fact, the Americans had the radar before the British ! The SCR-270 (Signal Corps Radio model 270) was one of the first operational early warning radars. It is also known as the Pearl Harbor Radar, that detected the incoming raid about half an hour before the attack commenced and all that before the US joined the War !!!

Really? So, tell us, mate, how we managed to have the Chain Home system operational in 1935, how we were able to see German raids building up in 1940, and carried out the first aircraft-borne, radar-controlled interception, and kill, in 1940.

code breaking computer?? never heard about this mate sorry?? sounds absurd

.
Well, mate, I suggest you read up about Bletchley Park, Enigma and Colossus, and how desperate the U.S. was to get involved, but, initially, weren’t trusted because it was felt that their security “system” was too full of holes.

British Standards had no input, during the war; there’s a report, by a B.S. executive(?) in the National Archives, which says that they offered their services, but were politely told, “Thanks, but no thanks.” Post-war, some wartime colours were transposed into B.S.381C, while others fell by the wayside.
F.S. is another post-war designation, applying to U.S. colours only (though “FS—–” does appear, at times, on U.K.-produced paint,) and shouldn’t really be used for WWII researches.
DTD 752 isn’t just red dope, but “AEROPLANE DOPING SCHEME OF MEDIUM TAUTNESS,” which has been replaced, in around April 1986, by B.S. X.26 (sorry, no idea what that is.)
The RAF Museum’s library has a box packed with colour samples (some dating from wartime,) and occasional samples (e.g. P.R.Pink, and Malta’s home-grown 1935 shades) will be found in files in Kew.

Initially, the Air Ministry favoured blending, but found that, at times, the blending was carried out by simply pulling the spraygun away from the surface, which led to almost-dry paint hitting the surface, giving a rough surface, and inducing drag. In early pre-Dunkirk 1940, following a meeting, at which a professor said that blending was a waste of time, a general order, on external finish, was issued, in which it was said that mats could now be used; oddly, there’s a 1937 Spitfire camouflage pattern drawing, in the National Archives, which carries exactly the same reference to the mats as appears on the later Mk.21 drawing, supplied by Tony (above,) which gives a hint that Supermarine never used blending, for some unknown reason.
When the war was in progress, Spitfires were being repaired at M.U.s, and factories of the Civilian Repair Organisation, who might not have had access to the mats, so would probably have had to revert to blending; one man I spoke to said that he “free-handed” an Oxford, but the foreman made sure that his overspray did not exceed half an inch.
In August 1942, Supermarine (and others) went from cellulose to a synthetic finish, which was smooth and matt (something paint manufacturers had found difficult, even impossible, to achieve in cellulose,) so maybe blending was less of a problem, but I’ve found no evidence of that, so far. Around that time, a new trade, of Aircraft Finisher, was created, which would/should have ensured better surfaces.
Post-war, blending returned, but, with a gloss varnish on top, maybe drag was less of a problem.

Don’t you mean “give em the bloody shovel” !

Not really; we keep hearing about “prisoner rehabilitation,” so I feel they should leave prison with at least one skill.

I’ve used two-part epoxy, like Araldite, but it needs to be heated above any ambient temperature, or it’s likely to soften in (for example) direct sunlight. For holes, heat in an oven, at low heat (100C is plenty,) then apply the epoxy, which will turn liquid and fill the hole(s.) If you need to have it standing proud, you’ll need to fashion a wall, of some kind (I used Blutak.) Put the item back in the oven, for about 30 minutes, remove, and allow to cool, which will allow you to sand down the epoxy, as necessary.
I’ve used the same method to assemble cast metal parts in models; the epoxy runs like water into the joints, so only tiny amounts are needed, and virtually disappear.
