    I believe the aperture for the underturret was kept but faired over. When we recovered sections of fuselage from a Mk III Lanc, this hole was very obvious. We thought it was the dorsal turret position but some things didn’t match up.

    The fuselage mounting for the FN64 turret was used to mount the H2S scanner (where fitted).

    I have a turret from an RNZAF Sunderland Mk.5 I have no idea if it from the nose or the tail – is there any way I can tell?

    This turret would never have actually carried armament, at least during it’s RNZAF service, as these aircraft were all operated postwar and in a benign environment.

    I realize no guns would have been fitted in RNZAF service but the basic turret arrangement was:

    FN11 (Front) – Two Guns

    FN13 (Rear) – Four Guns

    Turrets would have been manufactured by (Frazer) Nash & Thomson (hence ‘FN’).

    A car header tank / radiator cap should work just fine. Automotive systems pressure the coolant to about 15 psi which prevents coolant boiling to about 115°C.

    Some systems will have a (un-pressurised) reservoir to catch coolant that is expelled through expansion (via the radiator cap and a pipe that leads to the bottom of the reservoir). As the engine cools the coolant shrinks and a second valve in the radiator cap opens and the expelled coolant is sucked back into the system via the pipe.

    This sort of system would suit your needs as the reservoir can be large and it need not be at the top of the system or even that close (but it helps greatly if the radiator cap is at the top).

    Would it not be possible to mount the radiator cap on the inlet manifold at the top front of the engine? Not really sure of the layout of the meteor but isn’t there a thermostat housing there?

    This would have the advantage of being the place where air will tend to ‘pool’ with your tail down attitude (and a good place to top-up the system).

    That depends on what you are using as a coolant but assuming you’ll have mostly water with a minimum of standard automotive antifreeze (with corrosion inhibitor).

    Forgetting that this is a Merlin/Meteor for the moment (as a rough guide) a typical ‘earthbound’ engines coolant will expand by about 5% of volume as the temperature rises from 10°C to 110°C.

    Ideally the header tank needs to be at the highest point in the cooling system and have a flow of coolant through it so that air can be purged from the system.

    You’re going to have a lot of coolant obviously but if your only intending to run for 10 to 15 minutes you could just let the ‘excess’ coolant escape (via the system pressure valve) as the engine warms up and then replace it when the engine has cooled down.

    How are you going to regulate the pressure in the system?

    Yes, the USAAF sent an A-26 over to Brooklands, and it was fitted with a standard Highball installation (the codename for the A-26 installation was Speedee, but it was physically identical to Highball). The A-26 did a series of test drops in the sea near Eglin AFB in Florida; one of Wallis’ men was there for some of them. On several drops, the A-26 was VERY low (under 10 feet) and on the 28th April 1945, the bomb hit the tail with fatal consequences.

    Thanks for that information.

    How was the dropping height measured (in daylight) with the A-26 and Mosquito?

    The Sir Galahad was that the same one where you see the lifeboats being rowed ashore?

    Yes.

    The ‘Harrier’ loss looks like genuine footage of a Sea Harrier / Harrier flying low overhead but this is then spliced to footage of a (delta-winged) target drone being shot down during some missile firing trial.

    Interesting letters to ‘The Daily Telegraph’

    (Letters – May 5)

    The effects of bombing Stanley runway

    Sir – I must balance some well-honed RAF myths with facts (“Bombing Argentines with all the lights on ‘just wasn’t cricket’ “, report, April 30).

    Bombed or not the Stanley runway was never long enough to accept fast jets. Until the last night of the war Stanley runway was used continually by enemy Hercules aircraft and often by their Pucara ground attack aircraft.

    The Argentine Air Force did not move its mainland-based aircraft further north “so they couldn’t take part in the fighting”: further north is closer to Ascension Island, whence the Vulcan bombers operated.

    Throughout the war those of us on the ground and at sea continued to suffer the consequences of fast jets operating out of Rio Gallegos, a mere 304 nautical miles from Falkland Sound. I have been to Rio Gallegos: it has a very long runway indeed and would have taken considerably more than a couple of inaccurate Vulcan bombing raids to have closed it.

    Immediately after the Argentine surrender, I and a Falkland Islander drove the length and breadth of the Stanley runway looking for signs of damage and repair. There were none and the concrete was in as good condition as when I had been responsible for its security in 1978 and 1979.

    My friend and I marvelled, not for the first time, at the inventiveness of the Argentine engineers. Certainly the RAF’s bombing operations against Stanley airport were strategically useful but of little tactical value to us actually in the Falklands.

    War is not cricket. Perhaps the RAF of 1982 had not heard Admiral of the Fleet Lord Fisher’s dictum: “The essence of war is violence, and moderation in war is imbecility.”

    (Letters – May 7)

    RAF hit the target

    Sir – Ewen Southby-Tailyour (Letters, May 5) is wrong in his description of the damage to the Stanley runway.

    As Commander, Royal Engineers, I was responsible for its repair immediately after the surrender. There was one large crater caused by a 1,000lb bomb from the RAF Vulcan raid, and four smaller craters resulting from earlier Harrier attacks. (The Argentines had also created dummy craters to confuse our aerial reconnaissance.) Repairing the large crater and the large area of runway took about two weeks and 1,000 square metres of captured Argentine runway matting.

    Lt Col Southby-Tailyour is, however, correct in stating that Argentine aircraft were able to continue to use the runway, despite the bombing raids, by temporarily backfilling the craters. This, perhaps, is why his “recce” did not spot the true extent of the damage.

    The UEs explore the building, take photos and leave. Unless they find an open door or window, a gap in a fence or similar they don’t go in. It’s one of the rules, no breaking and entering.

    Unfortunately that doesn’t seem to be a rule followed by all…or that members are condemned for when they break it.

    See post #62 of the thread below:

    They’ve discovered an abandoned Concorde now!

    There is a ‘report’ from Brooklands featuring Concorde and the track banking.

    Some of the photography is quite good but the site seems deserted (and dark) and what is not clear is whether access was gained with permission or by ‘other means’!

    (Does anybody know? They give a date of 14/03/2007.)

    The original post makes no mention that this is a museum and that the whole site is open to the public and that you can pay to get in and that the money raised is used by dedicated people to collect, restore and preserve the things these people find so interesting!

    Other members have posted things like:

    “where is this place? it [Concorde] looks like its been left on a rally circuit or something with banks and a track like that.”

    “top explore guys!”

    The original post certainly gives the impression that this Concorde has been abandoned and that some kudos is due to those who ‘discovered’ and ‘gained access’ for the benefit of others.

    I suppose it is all part of the sites ‘urban exploration’ theme.

    Edit: I’ve just been reading the rest of the thread.

    “Superb photos, no chance of getting onto Concorde??”

    “Sadly no access into the plane, I did check the door though just in case someone had forgot to lock it-no chance!”

    “I was down there a few weeks ago but got spotted by a bloke in the building by the bottom of the hill climb track and had to bail. F+ck knows what he was doing in there in the middle of the night, I’ve never seen any security in that area before.”

    Words fail me! 😡

    Lieutenant Peter Fanshawe RN was the ‘sand dispersal’ expert during the tunnelling for ‘the Great Escape’ from Stalag Luft III although he was transferred to the Belaria compound northeast of Sagan before the actual breakout.
