    Bonehead!! LOL!

    Whats wrong with this situation ?

    Presumably front-wheel drive car with front snow-chains and just off the snow-line…you have to get onto a solid surface often to fit or remove snowchains.

    You can also view the progress on “live web cams” in the hangar….she is looking good…

    It is looking good, but she seems to have shrunk quite a bit compared to the partially completed mecanno replica in the background… 🙂

    Just kidding – i am looking forward to the flight as i have very fond memories of the Vulcan displays at Woodford Airshow (RIP), especially the ghostly banshee howl as she turned away from the flight-line.

    PS apropos of the Vulcan – my mum and dad remember the first flight of the prototype, as they were out in the countryside when this thing flew over fairly low and they said all the cars stopped and people got out and thought it was a UFO or something – apparently it was front page of the Manchester Evening News that night.

    One thing that i have seen work…

    CF cards use an IDE interface – a miniature version of the one found on hard drives. As with hard drives, if any one of the pin-connection holes should become obscured by dust or dirt, then you will get lots of read / write errors.

    So – and here i suggest MUCH caution – if the card still fails to read, then try gently blowing the connector holes (with a puffer brush idealy) to make sure they are clear and if neccesary, VERY GENTLY tap the card over a solid surface connector side down.

    use a puffer brush on the card interface inside the camera, too.

    I have personally recoverd a lexar card this way, when Image Rescue said it was duff.

    Apropos of the collision avoidance thingummy:

    1) if they could have foreseen this problem last year then, yes, it is another instance of bad planning / lack of anticipation.

    2) fitting it now, even tho A1 may never fly again is surely neccesary if only to make the planes sell-able ?.

    It rained a bit today………Roll on Summer, when the real downpours begin. :diablo: Enjoy….. 😀

    the worst bit of summer holidays is flying back home to return to work and is always made doubly worse by having to return to Ringway…..

    Why ? – i hear you ask…

    …because you start your descent in glorious sunshine and inevitably, just as the Captain announces “Cabin crew – seats for landing”, the plane slices through that famous manchester low cloud and the whole cabin is plunged into darkness and gloom and from there on in you cant see anything out of the windows because of the rain !!!!!

    … Which is when you realise you still have shorts, t-shirt and sandals on…. 🙂

    If succesfull in getting it aboard as hand luggage, Do you think she would have held it aloft for a laugh to mess up the final head-count prior to door closing……??? 🙂

    I wonder if the aircraft enginners of yesteryear were worried about repairing metal aircraft after years of looking after wood and canvas ones!!!

    An interesting point – i bet many aircraft engineers of yesteryear had many serious concerns over the reliability of those new-fangles “rivets”……

    But that would depend on how the strength of mended material compares with the strength of newly built material, or perhaps intact worn material. For example, a lot of metals are joined by welding in the first building, so welding in a patch would give about as much strength as the intact material had.

    How would you strengthen the spot where original fibreglass is joined to the patch?

    I dont know about the fidelity of repaired composites etc – we are now into “proper” engineering and its not my specialist field, so i cant help you

    Ah, I see.

    Can it be said that the kevlar/carbon fibre composites, while perhaps having a greater absolute strength than composites based on silken, hempen or cotton cloth or paper, have the same strengths and weaknesses and, once broken by excessive force, look like each other? And therefore can be mended in a similar manner?

    Broken carbon fibre looks exactly like broken fibre-glass. I believe it can be patched in a similar manner, although i suppose the question of repair feasability will depend on how load-bearing the broken bit was – same as using other materials in engineering.

    I also suppose that common sense dictates that the cost and complexity of carbon composites are only tolerated for areas of high stress – less stressed parts of an aircraft are presumably made of lesser materials.

    I got the BA shuttle back from london – manchester when i returned from Australia a couple of years ago.

    As everyone trooped over the airbridge and onto this plane it became immediatley obvious that it was a very large aircraft (A300 type something i think or similar – appols for not being a very techy spotter – anyhow it had about 10 seats across and would seat prob 200 people i guess)

    It was also amazingly clean and tidy and as the handfull of passengers sat down (twas first morning flight) ,i was talking to the stewardess and commented how nice it was and she told me that the normal aircraft was out of commision and that this aircraft had been side-tracked into service and that it was, in fact, a brand new aircraft on its very first service flight.

    It was an amazing flight – like being in a brand new empty cinema !!! 🙂

    PS and we shot down the runway and into the air at an amazing speed ..

    I often wonder if there has been a single milestone that has contributed to a major leap in civil air travel…… Symon

    747 for me – it bought ticket prices down – which led to mass air travel – which led to increased air tourism – which led to massive airport expansion – which led to airports appearing in more remote places as flying became the norm for the masses

    And so on… i really believe that the 747 will be seen in the fullness of time as being almost as significant in changing social trends as the invention of the train and the car were.

    Yes – a “composite material” is any material which has been formed by combining 2 or more other materials to create a new material.

    Usually, composites are made to create a material which has better or different physical properties to the individual materials used to create it.

    Often this involves the composite material comrprising of inner strands of one material woven together into a mesh to give strength, which is then covered in a liquid outer second material which sets hard in the final shape and gives additional strength.

    When people in ancient times created straw and mud huts, they created a composite material !!

    Concrete reinforced with steel rods in bridges and buildings is also a good example of composite material.

    Plywood is also a good example of this – each layer of wood is laid with the grain at right angles to the one below it, giving the finished plywood much greater resistance to splitting than a piece of individual wood of the same thickness.

    However – In terms of aviation and modern technology, “composite material” generally refers to a material using carbon and/or kevlar fibres woven into a sheet and then bound together using a resin.

    Carbon and Kevlar fibres have massive tensile strength in terms of stretching under load, but are fairly easily cut.

    Using them in composite materials involves laying down sheets of the woven material with the fibres running in alternate directions (like a mesh) and then using a high strength flexible resin (like epoxy) to bind them together and to take up any required mould shape.

    The finished material is then massively strong in all directions as the dried epoxy (or matrix component to be accurate) gives flexibility to the inner weave and stops it buckling, whilst the inner cross-weave resists tension and shearing forces.

    I think this is all correct, but stand by to be corrected by any super-techs out there 🙂

    With £100m in YOUR bank account, does it matter if your wife really reads it? 😀

    As the old gag goes…..

    “pack your bags, love, i’ve won the pools !!!”

    “pack my bags?….where are we going?”

    We arnt going anywhere – just pack your bags!!!!!”
