    just out of intrest les, there’s a chap with a website on the history of marshall aerospace. they did a lot of work on canberras years ago, and on the inputs page he has a list of all the canberras that visited, and which ones were broken up etc.
    there’s also information on quite a few other aircraft types as well.

    here’s a link to the canberra info…(hope its useful)

    i’d say its a hawk, if you look at the video, there’s an aerial in shot at the centre of the screen, down the bottom., a hawk has an aerial there, but an f16 doesn’t.

    they have a great car show at helmingham hall every year, well worth a visit if you’re in the area. didn’t notice any bleriots last time i was there though.

    thats not quite correct, some aircraft with conventional controls can still move the controls if all the hydraulics are lost, just that the load on the pedals/column is a lot higher. rather similar to you losing the power steering on your car.

    like many others posting here, i first came across chippies in the ATC. the nearest AEF for us was filton, and i always remember thinking that the runway was endless!
    doing aeros over the severn bridge was nice, although i remember one aircraft getting damaged when landing on a very windy day, the wind caught it, and from memory the wing tip was damaged, and the tailplane on that side was bent up and damaged!
    fast fwd a couple of years, i’m in the RAF at Valley, working on a VAS, looking after chippies during the summer for the visiting cadets. i seem to remember they had an incredible thirst for oil, although i think most of it leaked out, down the belly!
    i used to get no end of jollies over the summer, flying round the mountains of north wales, i remember one pilot giving a woman an almighty scare, we’d just taken off, and he wanted to simulate an engine failure, so he pulled the throttle back to idle, and looked for somewhere to land, the beach looked good, as we got down to about 100′, the woman walking her dog must have heard us, looked over her shoulder to see a chippie bearing down on her!…i remember the pilot saying, “i think that’ll do”, opened up again, and zoomed away.

    the rippling in the skin in the picture above looks like and normal composite skin. its very rare that you dont get ripples in large flat areas of composite construction, its just the way they are made.
    the ripples you get on conventional airframes are called panting, or if you are american, oil canning. quite often a brand new aircraft can have it, its just a result of the rivetting of the skins. but it can also happen on higher use airframes where the constant flexing from use or pressurisation can lead to a bit of stretching of the skin between frames.
    most aircraft have limitations for these ripples in the structural repair manual.

    2 hawks from brawdy had a mid air collision, one had a damaged wing and landed safely, the other lost all the nose fwd of the windscreen, including noseleg.
    it still flew ok, but there were concerns about the front crew member, during the landing, so he was told to eject. after he was gone the handling became quite unstable, with the CofG so far aft, that the instructor had to get out as well.
    there used to be a blurry picture of it kicking round in the circuit, with no nose. (the popular grafitti at the time was to draw a pair of feet sticking out!)

    we use LPS3/Dinitrol quite extensively in work to limit corrosion, this is painted or sprayed on belly skins, wing spars, trailing edge areas. the nearest commercialy available stuff to this is waxoyl. if you are using it, just make sure it doesn’t block up any drain holes. in fact it would be a good idea to go over the whole aircraft making sure all the area drains are clear, it doesn’t take a lot to block them up, just a flake of piaint can do it.
    px-24/WD40 is good because it dispels water, and can penetrate skin joints and other areas where water might lie for a while, as has been mentioned before, one drawback is that its very ‘thin’, and will run out after a while.
    things like exposed oleos should be wiped down fairly regularly with a thin oil like aeroshell 3/ OM12, or just 3-in-1 oil.
    make sure the cabin is aired regularly to get rid of any damp air, and if the aircraft is still safe for power on, do it as often as you can, and power up as many systems as you can. nothing destroys an aircraft like sitting idle.

    if possible get a program together, and gradually start taking panels off, painting the inside with waxoyl/wd40, and put the panel back on. make a note of the panels done as you go along.
    as has been said before, this won’t stop corrosion, but should go some way to slowing it down.

    i’ve seen c-130’s do this, the loady sits on the ramp looking out the back, reverse out of the slot, ramp up, and drive off.

    the 727 has hydraulics going to the flying controls as well as the undercarriage.
    airliners have mulitple, independant hydraulic systems, so even if you have a leak in one, you can use another system to move the control.

    in one book on hunters, there’s a tale of an aircraft getting into difficulties on approach to landing, the pilot abandoned ship, and the aircraft made a good, wheels up landing on the airfield by itself. and i’m not sure, but they may even have got it serviceable again.

    you can see the blokes head in the cupola in the head on shot, nice view from there!

    No, that wasn’t mentioned. The limiting factor of controls is often the availibility of hydraulic power. In some terms FBW has a disadvantage because it needs electricity while other flight controls directly pull on the actuator, therefore no need for electricity. Anyways, if hydraulic power is available so is electricity.

    For military aircraft this may be of use because I have alternative ways. both convetional controls and FBW have already proven their reliability. The next step would be to take away the rudder panels from the pilot or to reduce his authority on it to a absolute minimum (yaw damper rules and pilot nmay give advice).

    most aircraft have back up systems to provide power to essential controls and systems. they provide electrical and hydraulic power by a variety of means.

    it made me laugh the last time i went to brooklands, they had a fuel bowser there and the label said something along the lines of “Rare 1953 air transportable helicopter bowser”…we still use 2 of them in work at the moment!

    Well, depends what controls are disturbed, and to what degree they are disturbed.

    again, not necessary…..i’ve worked on aircraft where the whole operating systems are removed and overhauled, the control surface itself has been removed and repaired as required.
    everything is refitted, rigged ,inspected, and functioned… but no airtest. the aircraft has left, and gone straight to another airport, and then a transatlantic flight….but no airtest.
