    Sorry, don’t like Indian. However, as I said, unlike Hendon the food at Cosford’s fine.

    According to the Good Beer Guide, there is good beer available in Shifnal and Albrighton. Neither specifically state Bank’s Mild but they do say guest beers. The GBG will be in the car in case of emergency.

    Kev, not too many ramps at Cosford, but quite a slope to the whole site. Check your brakes. Looks like there’ll be less of the hooligan element tomorrow anyway.

    Don’t know about awe, I think total disbelief is more likely. 🙂

    Snowing here at the moment. Hope it’s temporary.

    Knowing very little about early Spitfire canopies and never having seen one other than in photos, didn’t the flat top ones also have flat sides? It would seem a bit odd to blow the sides and keep the top flat.
    I’ve always understood that what we know as the “standard” Spitfire canopy is the Malcolm hood.

    Kids – aaaaaaaaaarrrrrgh!

    No, I haven’t got any and I freely admit to being unreasonably intolerant of them.

    Hughie Greene too, I believe.

    No idea about either, but does the shape of screen 1 suggest an aircraft with an assymetric nose?

    I don’t know if anybody other than DH and Rotol made prop blades, but AFAIK, DH only used ali (and much later – steel) so it would seem to be Rotol.

    “Wooden Wonder to Whisper Jet”
    Also released as “De Havilland at Hatfield”.
    As I found out after I’d bought it. Those ******* at DD Video are always doing that!

    By redesigning the supercharger, Hooker increased the power of the early Merlins by a substantial figure virtually overnight.
    One good thing came from the Vulture. It’s supercharger was used as the second stage for the 60 series Merlins.

    The Rolls-Royce (Rover) Meteor was the tank engine. No supercharger and simpler carburettor. I’ve read 600hp, but I don’t know where. I’ve put Rover as the factory was part of the deal for Rolls-Royce to take over the jet engine.
    Would this be the same engine used in MTB’s? Any naval types about?

    Many years later, in collaboration with other retired designers, Hooker was responsible for turning the RB211 around and effectively saving Rolls-Royce.

    Over 2000hp for the Merlin in the Hornet, exact figure depending on which book you read.
    It was fortunate, as Mark12 said, that (Sir) Stanley Hooker was in the right place at the right time. He was probably the world expert on supercharging, it’s just that nobody, including himself, knew it to start with! He was a pure mathematician, with a particular interest in fluid dynamics. I’m confused just writing it down but apparently it’s perfect for improving superchargers.
    Autobiography, “Not Much of an Engineer” is an excellent read.

    No idea of ISBN numbers but according to the dust jacket of “Mosquito Racer”, Don McVicar also wrote “Ferry Command”, “North Atlantic Cat” and “A Change of Wings”.
    “Mosquito Racer” was published by Airlife in 1985 and is said to follow on from the previous three. Presumably they were published by Airlife too.

    I think the Packard Merlin was redrawn to use American threads etc. There may well be other differences too, but that’s the only one I’m fairly certain about.

    I would imagine that all mass-produced aircraft comply totally with the plans/drawings, or are supposed to anyway. With the Spitfire, don’t forget there was a huge amount of sub-contracted manufacturing so if the parts varied, there’s a fair bet they wouldn’t have fitted. I don’t recall reading any figures for the Spitfire but I think there were over 1000 sub-contractors for the Mossie.

    Steve, I don’t know if it’s the one you’re looking for but http://www.ddvideo.co.uk/ have a 1hr 32 min Sea Fury video.
    As you guessed, it’s PAL only. A lot of modern VCRs here will play NTSC videos. Don’t know if you get ones that will do the opposite.

    We’ll be there. Knowing my penchant for being late everywhere, assume I will be.
    Shouldn’t take you 4 hours, RobAnt. I do Plymouth from here in that time. I do cheat and go in the middle of the night though.

    Looks like the M6 toll road might save us a lot of time. Anybody used it yet?

    Re the tea. Total opposite to Hendon. Excellent tea and good food, fairly priced. If that’s changed in the 18 months since I’ve been there, don’t blame me.
