    Nice…the personal VIP transport for Mobutu :

    I wonder if the SAAF stripped the leopard-skin detailing off the steps after they bought it from him.

    Remember than all a/c are subsonic at low level so that the Scorpion is as fast as any fighter for low level defence.

    Perhaps the Scorpion’s potential opposition is a bit behind the times and only has MiG-21bis: good for 730 knots at sea level, transonic.

    Step it up a generation: a tankless MiG-29 can do 810 knots at sea level, an F-16C isn’t far behind. Both random examples and both supersonic.

    Now none of those will be doing those speeds as routine, and certainly not with ordnance, but a Scorpion realy doesn’t have the potential to intercept any competently-flown fighter without fluking the interception.

    Under the plan, the U.S. manufacturer is to establish a joint venture with a subsidiary of the country’s state-owned defense group Romarm to produce copters in Romania. The designed plant is expected to produce AH-1Z Viper twin-engine attack helos.

    I think that’s their third attempt to build the AH-1?

    The first was in 1995 / 96 with an agreement to build 96 AH-1F at Brasov, but that was cancelled in 1997 due to defence cuts.

    Then there was a proposal for the AH-1W to be built as the AH-1RO but that also flopped, around 1999 / 2000.

    Those are 76mm Sakr rockets, not 210mm.

    Polish LiM-6 carried combined rocket & bomb loads, latter 100kg inboard or 250kg outboard.

    No, certainly not 9g. With a full centreline tank the F-16 is restricted to 6.5g.

    Plus not just an airframe limit but also ordnance limit, usually in the range 5.5 to 7g. Mustn’t overstress the missiles.

    Just for entertainment, here’s a beautifully-flown barrel roll by a German Transall crew

    Barrel rolls are also ‘common’ in big-Boeing simulators, I’ll ask a colleague to watch the g-meter next time he does one.

    I just found the footage from an American TV show (probably the one I saw it on first)

    Not actually ‘Belfast’ as the narrator claims but the Newtownards air show, 1986. That air cadet went pelting across the runway and was first on the scene, but was relieved when Mr Wallis stepped out of the wreckage and said something like “Just a few scratches, my lad”.

    lol t-birds giving a more realistic airshow dropping sticks of snakes on the flightline?

    Not sure if it’s still the case but all Thunderbirds aircraft used to be on the active inventory and had to be restorable to operations within a certain time-period. During off-season periods they’d occasionally exercise that requirement.

    Edit: more pics of armed Thunderbird 10 from 1988

    I have a mysterious photo of a Boeing 707-023. It is purportedly from the Dubai Air Wing, but I am not sure of this.

    It’s actually a Boeing 720-023B, N7530A ex-American Airlines to Dubai Government. Later became A6-HHR but kept the N-reg simultaneously for a while to make international transit easier.

    Here’s another photo in that mid-1970s livery:

    Yeah I just assume at this point that only the export variants had the wing pylons plumbed.

    I think that’s correct.

    Certainly when the Red Arrows were deploying to Malaysia and China on tours they weren’t fitted with tanks. The latter trip required more than 40 stops for refuelling in total.

    I wonder how the interior compares to other transports around the world?

    Both the Il-76 and the old Shorts Belfast can fit an upper trooping deck, which filled that empty space.

    Maximum trooping configuration for the Belfast in RAF service was 110 on lower deck and 140 upper. Alternatively troops on the upper deck and cargo below.

    The C-17 wasn’t specified with attachments for an upper deck, so when trooping it always conveys lots of empty air.

    But in general unless there is some important tactical consideration it’s always better to move troops in chartered airliners. They’re designed to move lots of people and their baggage efficiently in reasonable comfort.

    Not Python 3, it’s a Kentron V4 R-Darter

    No, look at the rear fins. Set forward from the nozzle and quite high-aspect.

    This is an R-Darter / Derby. Trailing edges flush with the nozzle and low-aspect ratio.

    Some quirks of the design were discussed previously, but there is a lot that mystifies me about the choice of the F-84F for NATO.

    http://forum.keypublishing.com/showthread.php?317-F-84F-Thunderstreak

    It was said to be a sluggish aircraft with unfriendly handling, which killed many pilots. In contrast the NA FJ4 Fury was praised for its handling, as well as being much longer-ranged ( 3000+ litres internal fuel versus 2100 ) on the same engine and equally competent in air-to-ground versus air-to-air.

    Even the F-86H would seem to have been a better all-round multi-role choice than the F-84F for smaller nations.

    So why was was F-84F selected for provision to NATO? Reminds me somewhat of the P-47 being selected for MDAP after WW2 whilst the P-51 was primarily retained for USAF use.

    There was a Chinese prototype of an Il-10 with a turboprop, possibly a locally-built AI-20 variant.
