    The actual every day maintenance requirements for typical Soviet engines were much, much less than for Western engines. While any Western engines needs continuous checks on a very regulair basis, you can basically fly your Soviet engine without looking at it between the scheduled overhauls/rebuilds. These engine overhauls are far more often required than for Western engines, but on the other hand this means that at an operational level, engine maintenance is far less a burden than on Western aircraft.

    Soviet engines also tend to sound (AL21, R27, D30F) a whole lot better than Western ones, have far cooler and bigger afterburner flames, and often leave a very impressive smoke trail.

    Those are definately F-15A’s, not -C. They are from fiscal year 1977 (hence the small 77 before the large 100 of the serial), and those are all -A or -B models. In fact, with all modifications to A and C models, the only way to tell them apart is their serial number.

    Could still be Russian, but for export on the private market. Where did you get it?

    It’s the Yak-141 prototype crashing on the Gorshkov.

    Still nothing of seismological monitoring stations, it doesn’t seem to be an explosion at all.

    The TSR.2 was far more of a nuclear strike aircraft than the Tornado ever was, and was definately not designed to carry bulky external ordnance as the Tor is.

    No matter how impressive the TSR.2 was (in looks and performance), it was far more comparable to a really good F-105 than it is to the Tornado. The problem with cancelled projects is that they never got the chance to show their shortcomings. All operational aircraft do at some point in their careers. This gives a lot of leeway to the myth-builders, and especially with aircraft impressive like the TSR.2, CF-105 or B-70 there is no ‘operational’ information to debunk those myths.

    I like the second pic with the moon in the background, it is a nice looking plane, and lets hope that it’s troubles are now over!

    Now all we have to do is fix the I-23 and we’d be right again 😉

    Problems with the Orlik? It had a relatively troublefree development (with some time spent trying different engines) and AFAIK a very decent operational career.

    The I22 on the other hand is a total disaster.

    I hope your own collection does NOT contain any Russian F-14s?

    After returning to Israel, the F-21s (back to being Kfirs again) were all grounded and put into storage for being structurally beat. I don’t know how run-down the aircraft were when they went to the US, but i expect them to have been properly inspected and found OK before being accepted by the USN and USMC.

    Funny though: the ‘modern’ F-21 and F-16N were flown through their fatigue life in only a couple of years, whereas the F-5 and Skyhawk (also compare the A-4’s record in IDF/AF service) flew such missions for decades…

    True, FL530 is awfully high and the air is awfully thin up there. I’d love to learn some more specifics about it.

    Doing maneuvring at M 1.98? It’s probably got to do with the extreme altitude, but isn’t the F/A-22 limited to M 1.8? Anyway, maneuvring at those altitudes indeed requires thrust vectoring rather than aerodynamic surfaces… Then again, if F-104s and other fighters used their thrust to reach altitudes far higher than their wings were capable of, it’s only the next step to use thrust vectoring to bring maneuvring up to such altitudes.

    The missile shot while doing 7g impresses me a lot more, actually. Did they open the doors of the weapons bay under such strain too? Although i’m already amazed if the doors closed again neatly.

    The Cheetah C is indeed more of a Kfir than a Mirage, except for that oh-so important rear fuselage. The Cheetah still has the Atar engine and MirageIII-style rear fuselage, and not the rebuilt one of the J79-powered Kfir.

    While the airframes of the Cheetah C’s indeed came from Israel, they are probably composite Kfir/Mirage airframes rather than pure Kfirs. I offer a plastic container of the cheapest South African wine for anyone with a clue where those Mirage rear fuselages came from…
