    Excellent, thank you. So the Emergency Powers (Defence) Act did indeed grant the power to authorities to requisition property. Subsequently the Compensation (Defence) Act established guidelines for compensation.

    http://www.legislation.gov.uk/ukpga/Geo6/2-3/75/introduction?view=plain+extent

    Clause 4:

    (1)The compensation payable under this Act in respect of the requisition of any vessel, vehicle or aircraft shall be the aggregate of the following sums, that is to say,—

    (a)a sum equal to the amount which might reasonably be expected to be payable by a person for the use of the vessel, vehicle or aircraft during the period of the requisition, under a charter or contract of hiring whereby he undertook to bear the cost of insuring, maintaining and running the vessel, vehicle or aircraft, and

    continues with verbiage associated with damage and loss.

    So the owner received a payment, on a monthly or longer timescale, roughly equivalent to chartering the aircraft. Seems reasonable; gave the forces the aircraft they needed in a crunch, whilst financially discouraging them from holding them indefinitely.

    I vaguely remembered a spread of Botha details photos in the Flight archive, starts from here for four pages:

    As usual the fuselage sides are generally obscured but one shot does show three small windows to starboard, tucked under the wing. Might be some other useful shots there for you.

    In another issue was an unusual view of the split bomb-bay.

    F-4B testing semi-conformal AIM-54 carriage for McDonnell’s VFX submission. Lacking sufficient fuselage depth, the launch trapeze was built into a cut-down fuel tank.

    The ‘real thing’ would have carried the missiles submerged into the fuselage like a Tornado ADV, rather than on pallets per Grumman’s design.

    For the cost of one CH-53K you can buy three CH-47Fs and pocket a cool $20m.

    And here I thought USMC was about doing more with less.

    First they’d have to develop a navalised Chinook. One that can stay embarked for more than a few days and doesn’t need washed-down afterwards. And which is resistant to the EM spectrum of a ship.

    Then the Marines would have to determine how to fit two Chinooks into the space of one Stallion on a ship, in order to provide the same or better lifting capacity.

    Then they’d have to throw away those decades of accumulated ’53E spares and buy new inventory for the Chinook. Plus new training & process development.

    Add all that up as program cost and divide by total number of airframes and let us know how much a Sea Chinook will cost. It certainly won’t be anywhere near the 47F’s flyaway, no-spares, no-training sticker-price.

    *Then* try to estimate the cost of monopolising to one heavy-lift capable manufacturer for the future. How much would Boeing charge for a Chinook without competition from Sikorsky, their only non-Mil rival.

    Scud probably isn’t the best example as it was single-stage, plus the modifications the Iraqis had made to increase weight often caused structural failure and large falling chunks before the SAMs even approached them

    Nike Hercules was routinely intercepting similar Corporal missiles in the 1960s and I believe chunks of motor fell to earth but not much more. They also intercepted the second-stages of other Hercules and left nothing but light debris.

    what about the NC Fallout from such detonation, seems to me you would have to put such missiles and SAM systems on far remote area, or pointing out towards sea or whatnot..

    Which is why Canada ended-up with Bomarc missiles in the 1960s; there’s a whole story about NORAD’s basing-options that led to that. “Lovely country you have there, be a shame if we had to use our nuclear-tipped missiles to drop irradiating wreckage on it.”

    However nuclear-tipped SAMs have different warhead designs and terminal effect to nuclear-tipped ABMs, which attempt to render the inbound nuclear warhead inert through frying its electronics with x-rays.

    Why would Sherm and Brown lie about a retired program?

    Why would the USAF lie about it in the Dash-1? That was a restricted-circulation document ( might even have been NOFORN at one point ). If the RLS panel made it into the Dash-1, which was issued fleet-wide, I’d believe that over the memory or NDAed statements of two former project staff.

    Until a former crew-member speaks out I suppose it’ll just have to remain an enigma.

    There is a beautiful underside view of the F-117 here:

    http://www.airliners.net/photo/USA-Air-Force/Lockheed-F-117A-Nighthawk/1268420/L

    and there do indeed appear to be two hatches outboard of the radar-altimeter diamonds, but with the typical stealth-serration edges one would expect, rather than the straight-edged design shown above.

    I think there might be some careful phrasing going on; note that the designer states that “This picture doesn’t look like anything that was ever put on a F-117A airplane”. Which does indeed appear correct, but doesn’t state that the RLS wasn’t fitted.

    there is a video of it
    i dont know why people hate on it so much, im all for different planes, different unique designs – just like pre ww2 and ww2 now its just US, Russia and france that are making planes with china copying everything

    I don’t think anyone ‘hates’ it, just that there’s a healthy dose of scepticism about the design and its purpose. Not helped by the manufactured-hype about it being a ‘stealth fighter jet’ instead of just saying it’s a test-bed.

    Aviation enthusiasts, those with a open press at least, have been subjected to 60+ years of ‘artists impressions’, models, mock-ups and CGI which have bred a level of cynicism as well as a sort of ‘filter’ for separating the feasible from the wishful.

    The reliability and precision of the 30+ years old Tomahawk remain striking.

    There’s not a lot in common with the current TLAM Block IV and that of the 1980s other than the basic airframe ( even the engine is different). Primary navigation is now by GPS, rather than inertial with TERCOM updates, so that they can operate much more accurately over poorly-mapped regions or after prolonged overwater ingress. I think they still have the capability for scene-matching terminal guidance but again GPS is available.

    Have there been any post-strike photos issued by the US DoD?

    – As per what was reported, the flight time from the launch platform to the target area took just 60 or more seconds and the entire strike lasted about approx 15 mins (3.42 to 3.56 MSK). This was a good saturated launch with minimum time intervals.

    Flying-time for TLAM from ship to target would have been around 15 minutes, assuming a minimum great-circle distance of 130 nm and ignoring any detours or jinks.

    These are not multi-Mach ballistic missiles, just small aeroplanes that fly fairly quickly at low altitude. For comparison their penetration speed of around 500 knots is slower than that of a Tornado loaded with JP233 which aimed for a minimum of 540, despite the drag. With slick ordnance they could push up to the mid 600s.

    When suffering a hit that causes ammo cook off, any tank will go “Jack in the Box” and blow off turret. There probably isn’t much of a difference in the % of time that occurs be the tank Russian, U.S., French, etc, even with the inclusion of blow off panels on ammunition storage.

    Absolutely there is a difference in the % of time. The late-series M1 have the primary ammunition storage in the turret bustle, with an overload of six rounds in the hull; either the latter are used first or not carried. Hence a hull-hit won’t find any charges to cook-off.

    Challenger 2 has wet-storage for all its bagged charges, in the hull but at least protected. I don’t believe there has EVER been a turret-flip on a C2.

    Leopard 2 has its primary ammunition storage in the forward hull beside the driver; not wet-racked and very dangerous now that ATGM pose a risk of breaching the hull.

    Not in-flight but a better view.

    With the air sampling missions there was also a need for CBRN training of the crews, and inflight / pre- / post-flight personal contamination monitoring and testing. It wasn’t just a case of strapping on pods and launching.

    What an attitude.
    Its a flying Spitfire.

    No, it’s a flying replica Spitfire. “The stencilling on the original firewall has been accurately copied and applied to the new firewall” etc.
