    I guess today might be a good day to post this, a view of the Mohne dam from above which I took earlier this year.

    Really? I’ve had several Spitfire pilots tell me that the difference is barely noticeable.

    I was told this last Saturday and didn’t question it then. Let’s see if I can work it out:
    – I found this figure online, is it correct? Wing area: 22.48m2 (21.46m2 with clipped wing)
    – Let’s assume a max lift coefficient of 1.4 which may not be correct but is in the general area, and as we’re comparing two equations the difference won’t be that large.
    – Loaded weight is around 3331 kgs for a Mk.IX Spit (correct me if I’m wrong).

    Using the lift formula and solving for V we find that for the full size wing the stall speed is in the region of 80kt and for the clipped wing it is 82kt. That’s less than the figure I heard but you have to take into account that the different wing shape may affect the stall characteristics as well.

    Correct, but as this Spit has a history of landing incidents and the clipped wings add at least 5 knots to the stall speed, the owners have decided that these wingtips will remain attached!

    That type of wing fold was used on Hellcats, Wildcats and Avengers (among others). I would guess that these are Avengers. There is a long glasshouse with what appears to be a turret at the end of it.

    There are more odd items, such as behind the canopy, seems to be a cover or a structure there. And at the righthand side there is something fastened to the side of the cowling which doesn’t appear to belong there. Ground instructional airframe sounds allright considering these things but which one?

    I’ll have to second the recommendation for the Plustek range. I’ve got a Plustek 7400 and it produces very nice results, especially when I consider that it was a relatively cheap buy.

    I don’t use the multiscan features a lot (prefer to use photoshop for the shots which I do want to improve) but did invest in a newer version of the Silverfast software which eliminated a weird effect I got in some scans where reddish areas appeared in shots with a lot of blue in them.

    This was scanned from a 14 year old negative:

    Yup top one VC10 and as it as a fin tank I would say a C1K, none tanker variant didn’t have dispense part if memory serves me correctly or the totaliser, as an ex VC10 engineer… nice

    I don’t think it is a C1K as those don’t have a HDU. VC10 tankers with both a fin tank and a HDU are either K3s or K4s, and seeing as the K3s are still around it must be from a K4. Possibilities are:
    – ZD230, scrapped at St. Athan April 2006
    – ZD235, scrapped at St. Athan January 2004
    – ZD240, scrapped at St. Athan 2006
    – ZD242, scrapped at Boscombe Down February 2011

    ZD241 was in the Falklands until 8 March. It has been replaced by ZA150, I expect that it too will fly back to the UK before being decommissioned.

    It was only a delay for a day… ZD241 has now been retired to Bruntingthorpe, landing for the final time on 21st March around 12:48LT. Photo below by Alan Kenny.

    As it turns out ZD241’s last flight was canceled today, it is now scheduled to go to Brunty either tomorrow or the day after. Updates may appear in this topic on my forum if you’re interested in the details: http://www.vc10.net/forum/viewtopic.php?f=4&t=544&start=195
    I’m hoping someone will be able to get a few shots of its last flight, it will be the end of an era as the last BOAC Super VC10, ex G-ASGM, touches down for the last time!

    Edited to add: the three ship did fly in August 2012 but XV108 stood in for ZD241 as the K4 was delayed in maintenance, it did perform some engine runs on the detuners on that day but that was all the noise it managed to contribute to the festivities. There’s a nice photo about halfway down this page: http://www.vc10.net/History/RAFVC10s.html

    Have K.3s ZA147, ‘148 & ‘150 all been removed from service then?
    I was under the impression that they, C.1K XR808 and K.4 XD241 make up the current fleet?

    That’s correct, although ZD241 will (if the plans worked out) have made its last landing about three hours ago, leaving ZA147, ‘148, ‘150 (currently at the Falklands) and XR808 as the last four active VC10s.

    The news release can, if read quickly, give the impression that this was the last K3, but this is incorrect. Still sad to see that these K3s are going too…

    The report is pretty clear and I’m glad that the BBC have taken only the salient points from it, without any inference.

    I agree that given the handling qualities of the DH53 one would have to think twice about flying it but on the other hand this was the ideal situation for it. An operator with sensible practices for operating the craft, a competent pilot with all the needed qualifications and lots of experience and so on. The only thing that was an unknown and turned out to be the killer on this day was the wind. It is easy to underestimate the wind from ground level, especially when sudden changes or as in this case large trees influence the local winds. The fact that the chief pilot and the other DH53 qualified pilot observed the take off and did not see cause for concern tells me that the pilot may never have seen this coming. Sad.

    Right, so that gives the end of the period as 70s, but when were they first introduced? Was that before, during or after WW II?

    TerryP, that is brilliant, thanks for that! Bellarine, Tangmere1940, I don’t think that the current owner is looking to sell it. As I haven’t been in touch with him directly it is unclear to me how he got it but for him it has a novelty value, being connected to his own trade as a navigator. He is more interested in the story and/or background behind the sextant.

    Can anyone shed more light on which aircraft used these sextants, and in what period?
