    Surely those wipes are for wet sealent, or am I mistaken?

    Oh!, regarding the removal.

    Hard work and the scrapers mentioned about. MEK can be used to clean a surface once it has been scraped free, if it don’t kill you first. Not even sure MEK is available outside the industry.

    Don’t experiment with different solvents. If its not in general use in the aerospace industry, it might be because it causes corrosion, or otherwise damage something. Use aerospace recommended solvents.

    Wear a mp3 player and try to think of something else. Oh, and just wait untill you need to remove it from the fuel tanks…….

    What you need to ask for is PR1422 B1/2 or A1/2. Depends on the drying time (B1/2 takes longer to set, but is a much better compound). Its a two part mix – if you get it in a tub, be warned, you’ll be stirring it for hours! If you manage to get it in the semkit its a much better way of applying, just don’t accidently unscrew the plunger while you are mixing… pump the plunger and twist it clockwise while you are doing it. It should usually take about 10 minutes of hard graft to get the stuff mixed properly…. oh, and wear gloves. Its nasty stuff…… stinks too….:D

    Light Aero (LAS) sell it. Thats your sealant anyway…

    To remove it, I echo what has been said before – MEK or Trichloroethane (Trike) – both of which will kill you horribly – and a non-metallic scraper… oh and alot of time….

    Two things regarding the mixing:

    First, be sure to mix it properly. The semkit can be attached to a slow turning drill, so you only need to do the pumping (keep the semkit cylinder fixed in a vice). You cant overmix (unless you spend so much time, that the stuff hardens), but you can undermix. I can’t recomend the tub type sealent, as the mixing is too difficult and messy.

    Second, if you are using small amounts many times a day, dispose the semkit into a number of small plastic bags and keep these in the freezer. The sealent will stay fine for at least a day, or two (don’t let people tell you, that it lasts forever in the freezer). Just give it a few minutes to defrost. Cut a corner off the bag and use it as you would apply icing to a cake.

    Final warning: this is toxic stuff. Wear protection and have proper ventilation. Also ensure that people around you are aware of the use, so they can protect themselves.

    I normally apply a very percise amount on the job, then somehow manage to dispose the remaining compound onto my coveralls, shoes and gloves 😀

    I was seriously looking into this package a few years ago. Unfortunatly I was unable to muster enough people to get the project rolling, and unable to finance it myself.

    For anyone wanting to fly a Pembroke, its the best darn buy you can find. One AC has had the wingspar mod done by RAF, so its good to go structure wise.

    Hope they find a good home.

    Richthofen had a number of nicknames, most likely of different parts of the front.

    The French called him “Le Petit Rouge”, which means “The little red”. The British knew him as “The red knight”, “The red devil”, or the “The red baron“.

    I have not heard that “The red baron” should have been a post-war nickname (and I have read a few books about Richthofen), except in Germany where he was known by his correct title “freiherr” (which is a German Baron). During the war, the Germans mostly called him by his full name, or simply “von Richthofen”. Just as most aces are known nationally by their full name.

    I think people settled on “The red Baron” as a token of respect (after the war), as “little devil”, or “little red” was deemd unsuited for an aviator of his status.

    Eventually even the BBMF Lancaster will become static too. There is a certain lifespan on an airframe and even with the best of maintenance, it will not remain safe forever.

    Hopefully there are plenty of years left in PA474.

    As for the flying vs static debate, I strongly belive in a large pool of static aircraft. From a historic perspective a rebuild is not of the same value. There will always be deviations from the original recipe. Different rivets, a slightly different alloy, parts from a later/earlier model, or some other diviation.

    I think its very important, that we have “true” examples of historic aircraft in a safe environment (or as true as possible). Once the building craft has dissapeared (sometime in the future) historians will be able to research an original and learn how it was built.

    Its great that there are people out there, who will spend a lot of money getting historic aircraft airworthy, but its even greater that RAF (who don’t owe anybody anything) are able to restore and display such a large number of aircraft.

    If I should point my finger at anything, its the museums who are unable to take proper care of their exhibits (thankfully most do a good job). Seeing a static aircraft decline is not something we should be exposed to.

    The price of restoring a less popular aircraft, might be the same as restoring a Mustang, or Spitfire.

    The two famous aircraft will always find a marked, and the original owner can make some (if not all) of his investment back. I don’t think its so for the less famous aircraft. So from en economical point of view, restoring a famous type will tend to be a better investment (even if its not an actual investment).

    Beside; there are technical and regulation questions, that already have been answered for those famous types. Starting on a type with no current airworthy example, would add a lot of extra work.

    If somebody think a type is missing when they visit an airshow, its just about getting a project started and getting one in the air. A shame its so hard to get such a project going.

    It would have been funny, if they had a mindboggingly complex “kill algorithm”. Where aircraft performance and pilot skill was used in calulations.

    Bf-109E vs Boulton Paul Defiant = 0.43 Kill in daytime and 0.67 for night.

    Then add the pilots “handicap”.

    Adolf Galland handicap = -0.15

    For killing one Defiant. 0.43 + (-0.15) = 0.28 Kill.

    It actually sounds like something my government would introduce.

    What a nice and dramatic series of post cards.

    Photography around the time of WWI was mostly done on individual plates, not sure if it would have been possible to capture the fall by rapidly changing plates. But there could have been more than one camera trailing the airship.

    There might also have been a problem with exposure time, which was quite long, particular for night time photos.

    On the other hand, the photo “doctoring” was not really great at that time either, so a completely fake photo would stand out. Its hard to judge on the small pictuers here.

    My guess it that its a combination of both. A best effort night photo, then doctored a bit for details that didn’t make the plate.

    Looks like a well made site.

    Can’t wait to have a browse around tomorrow.

    You should have a look around this site:
    http://www.flensted.eu.com/

    It covers stories about losses in and around Denmark, some of them in fine detail with pictures, memorials, and even some with survivors visits. Maybe you can exchange some stories and pitcures with the owner.

    Good luck with it.

    BAC TSR-2.

    I’m pretty sick of listening to what is “would” have done, how many records it “could” have broken and its general percieved brilliance.

    Best TSR-2 quote on WIKi:
    “The aircraft’s nosegear vibrated at the resonance frequency of the eyeball, causing the pilot and navigator to suffer double vision during taxiing. The problem was dealt with by adding damping into the already extremely complex landing gear.”

    I prefer aircraft that have actual proved performance, not calculated maybe performance.

    Its maybe a sign that collectors have more money to spend.

    The item was unique and £2000 might not be “ludicrous”, as it will only become more valuable with time (im not talking about an investment, but simply that it certainly won’t suddenly decrease).

    Compared with the P-51 “project” (a few instruments and parts of the hood) resently offered for £5000 (not sold), and a few other items with ludicrous starting prices, this item found its “natural” value by bidding and not by having a crazy starting price.

    £2000 would get you a lot of other nice parts, maybe even a good cockpit, but having a Halifax throttle box would be worth two non-Halifax cockpits to the serious Halifax collector.

    Fair deal for both buyer and seller. Hope it gets on public display.

    I’m no “Belly-landing” expert, but that looked just about as good as they get. Good airmanship.

    Thats also possible, did the Spanish air force use them for towing?

    I flew target tow once (as a winch operator), but we had the winch inside the cabin.
