    I think it was an A4 that got a kill using Zuni rockets.

    Ta, must be my middle-age brain sagging again 🙂

    Has that happened since that, prop plane shooting down a jet aircraft ?

    Yes a Royal Navy Sea Fury bagged a MiG-15 over Korea and at least one Skyraider took a MiG-17 over Vietnam, with a Zuni rocket I believe.

    Indian Air Force An-12 bombers, 1965. I think they did the same again in 1971.

    http://www.bharat-rakshak.com/IAF/History/1965War/1157-Augier.html

    Iraqi Air Force used Il76 as a bomber against Iran and their Iraqi Peshmarga allies in the battles in the spring of 1988. Areas inside Iran and along the Iraqi border were bombed.

    They employed “simple” barrel bombing technique.

    I don’t have a web reference to hand but the Iraqi bombs were developed in co-operation with Zimbabwean ( ex-RhAF ) technicians based on the Golf series ( diesel +nitrate fertiliser ). Very potent blast weapons, effects similar to FAEs but easier to deploy and not as susceptible to winds. IIRC the Iraqi weapons were built on pallets.

    Well the new Thomas Cook ‘livery’ is so low-viz that it should blend in nicely with the overall grey Voyagers….

    wasn’t these can be calculated by computer , thus negate it ?

    You cannot determine the movement of air cells all the way to the target; not in real-time, anyhow. The computer can factor-in conditions at the launch point ( hence all those boom-mounted sensors on an Mi-24 ) but the rest of the range is unknowable.

    Helicopter cannon suffer from barrel whip, mount vibration and airframe flexing which affects subsequent shots.

    As has been pointed-out above: in air-to-ground engagement this is actually conducive to the effectiveness of suppressive fire.

    Cargo compartment sizes:

    KC-390: Length 17.75 m X width 3.45 m X height 2.9 m
    Payload: 23,650 kg

    C-130H-30/J-30: Length 16.9 m X width 3.12 m X height 2.74 m + 3.12 m length on ramp
    Payload: 20,000 kg

    C-130H/J: Length 12.31 m X width 3.12 m X height 2.74 m + 3.12 m length on ramp
    Payload: 20,000 kg

    The actual pressurized hold length for the KC-390 is just a bit over 12 metres, right about the same as the C-130H.

    That’s because there’s a big swing-down internal pressure bulkhead which separates the main hold from the conical tail-and-ramp section.

    Not too bad if you’re operating below 10,000 ft ( SAR etc ) but a hindrance for longer higher-altitude flights. A real pity they couldn’t seal the ramp as pressure doors like Lockheed managed 60 years ago :-/

    Gripen shows off British engineering. How cheap could they be leased?

    I was just going to suggest an evil idea: some ex-Luftwaffe Alpha Jets like QinetiQ currently fly in RAF colours. But I prefer yours 🙂

    and wouldn’t it be cheaper for them to use the same trainer that the rest of the RAF already uses?

    Unfortunately not; the RAF has a fleet of 28 Hawk T.2 and that’s all. There’s no plausible way they can fund and operate another 11 purely for an aerobatic team.

    Once the T.1’s life expires it’ll probably be the end for the Arrows unless their pilots can accept a culture-change to flying turboprops.

    Anyway, the original AFM journalist has responded by stating that the newspaper has conflated 736 NAS’ potential future equipment with the of the Arrows; the Arrows were never discussed in his original article.

    According to the wiki article, the A-10 has a service ceiling of 45000′, this is well enough to launch from altitude. The A-10 carries the sniper pod, so it is as good as any other plane.

    Any time you see the phrase ‘according to Wikipedia’, substitute with ‘according to some guy in a bar’.

    An A-10 is not going to go much above 29,000 ft in clean configuration and is not going to go anywhere near that height with fuel and ordnance. For refueling their tankers usually need to come down to meet them around 15,000 ft!

    Operating in the mid-teen levels over a MANPADS threat is still risky. IS also reportedly have captured heavier AAA from Syrian forces that can reach those altitudes.

    Most allied aircraft seem to be oeprating around 24,000 ft to stay above that. An A-10 is fairly useless at that height, can’t use it’s trump-card cannon and cruises very slowly.

    I don’t believe the deflector is related to the propwash.

    One needs to break the fuselage laminar flow to prevent a jarring transition for jumpers. Best that they exit straight into turbulent air.

    I’m sure a parachutist could provide some insight.

    Rather an oldie but thought it might be of interest. Brief cine footage of a Nigerian MiG-17 in action over Biafra in 1968

    Unfortunately the Arrows aren’t much of a promotional sales benefit nowadays, flying a 40-year-old design in the face of M346s and T-50s. Perhaps some top-up orders to old faithfuls.

    RAF recruitment is consistently over-subscribed, particularly in the ‘sexy’ trades like driver, airframe. So any ( debatable ) loss of recruitment volume from disbanding the Arrows would in my opinion be of little consequence. Might actually made the load easier for AFCOs, since applicants would tend to be those with a deep interest in the forces and aviation rather than ‘jets are cool!’ types.

    Ed Heinemann?

    I don’t believe he had a license, I do know he went up in the back of a TA-4 once and that was the only time he flew in one of his fighters.

    Here are a few Iraqi F-7s. From right to left F-7M, F-7B, F-7M, I always thought the one on the left was a slighly awesome shot.

    Interesting that the CH-53 is carrying the F-7 tail-first. I wonder if that is to prevent the wing generating lift and perhaps bouncing around on the harness?

    Footfall will be the final arbiter of their success. That’s ultimately all that matters.

    I disagree with that being the measure of success of a museum. Preserving artifacts with the goal of socialising history – that’s how a museum should be assessed.

    Having thousands of people tramp through is pointless ( in the wider context ) if they take no new knowledge with them. Might as well go for a walk in the park.

    My concern with this Defiant moving is that the socialisation aspect is lost. It’s rare public knwledge that anything other than Spitfires existed during the BoB, now there’s even less chance that they’ll learn otherwise.

    ‘We went to a museum and they had an aeroplane called the Desperate which fought the Luftwaffe. At least I think that’s what it was, they wouldn’t let me write it down’
    ‘Oh you’re having a laugh aren’t you! We had Spitfires and Lancasters.
