    John McCain — war hero, political giant — dies at 81

    @2:12 & 3:50 McCain

    The Hanoi Hilton was one site used by the North Vietnamese Army to house, torture and interrogate captured servicemen, mostly American pilots shot down during bombing raids.[15] Although North Vietnam was a signatory of the Third Geneva Convention of 1949,[15] which demanded “decent and humane treatment” of prisoners of war, severe torture methods were employed, such as rope bindings, irons, beatings, and prolonged solitary confinement.[8][15][16] When prisoners of war began to be released from this and other North Vietnamese prisons during the Johnson administration, their testimonies revealed widespread and systematic abuse of prisoners of war.[13]

    The pilot of a T-28 Trojan survived the crash at Anoka County airport (WI).

    I wasn’t aware that there was any Trojan still in service in the US?!

    that was mirage F1 which is BVR equipped while Mirage III in PAF service was not

    Yes And still the F-1 had to fly low and avoid the merge…

    Among the newest Block 3F F-35s, [Chief of Staff Gen. David] Goldfein said squadrons are turning in mission capable rates of 80 percent, which is higher than USAF standards and far better than aircraft at this level of maturity.

    Comparing notes with his counterpart, Marine Corps Commandant Gen. Robert Neller, Goldfein said both are seeing the same readiness levels “at home and deployed.”

    You can compare to the situation faced by the French contingent in Chad facing Lybian Mig23 or the South Africans facing similar Angolese forces: in both case the Migs (helped by SAMs) posed a considerable threat to the Mirages essentially dominating the airspace.

    Top 100 Defense companies

    Analysis: https://www.defensenews.com/top-100/

    Interestingly BAE is still 3rd, Raytheon surges on the 2nd position and despite the fact that among the top 10, two of them are french companies, the French industrial politics still lean heavily in favor of the 44th of them (last year ranked 51) just as if the Tour de France should be commented from the tail-end position*…

    *Despite the fact that their revenues surged 57%, their position barely moved indicating that their business model stalled.

    My dear Swerve, Easily like easily avoiding scrutinity ( since the story is dead with the regime admitting having displayed only an indigenously upgraded US plane). 😀

    I used the verb to smuggle

    1 : to import or export secretly contrary to the law and especially without paying duties imposed by law
    2 : to convey or introduce surreptitiously

    Why would they reverse engineer something that they can easily smuggle-in?

    What is important is the rate of variation of the cross section. That’s what says your second order derivative in the Whitecomb equation and why the sinusoidal factor is introduced to follow the sear body pattern (sorry this was added to my earlier post but Keypub subsequently crashed yesterday). A good example and analogy with the F-35 (see at the bottom of the page on the link below) is the bump on the 747 that will open a more complacent range of volume distribution.

    A good example is the Boeing 747, known for its distinctive “hump.” This hump, which houses the cockpit and upper passenger deck, increases the cross-sectional area of the forward fuselage and has the effect of evening the volume distribution over the length of the aircraft. As a result, the 747 is able to cruise efficiently at a slightly higher speed than most other airliners since the increase in transonic wave drag is delayed.

    So, true also in aerodynamics, curves are the sexyest attributes!

    The US Navy’s fight to fix its worn-out Super Hornet fleet is making way

    The U.S. Navy is slowly making progress to restore to fighting condition its hard-worn fleet of F/A-18 Super Hornet fighters, which last year had just one in three of its fighters ready to deploy.

    Today, almost half of the Navy’s 546 Super Hornets are considered “mission capable,” a sign that the readiness investments made in the Mattis era are beginning to bear fruit.

    More Hornet, more honey.

    > Frontal section + finesse ratio + wing design limit supersonic performance. This is serious since conditions capacity to control engagement and survivability both in A2A and A2G
    > Short body and engine placed in a forward position limit internal space for weapons, which detracts from the aircraft’s capacity as strike platform.

    Frontal section: if you mean the total projected area of the fuselage as a mean to estimate the drag of the airframe, as it was discussed thousand of times here, you have more chance to fall off the real value than to get a proper estimation. here is an exemple of how non-intuitive drag estimation is :

    262335
    Finesse ratio is certainly not one good parameter to estimate the drag. For exemple the bulky F-4 Phantom outspeed the pointy X-3 by far that compare even poorly with the F-100!
    Wing design: It’s all about providing lift. With better lift and trim management for example, you need far less surface area. The formidable F-35 load carrying parameter is a good hint at what kind of lift that tiny wing and lifting fuselage can generate. Such as is the 50+ AoA performance.

    The position of the engine is not as much dictated by the VTOL config than by other requirements. Stealth come in my mind as the strongest one: with the airframe surrounding the engine nozzle, you hide critical surface from radars, wash-out more air in the hot airstream or reduce your trim drag and surface deflections using far projected trim surfaces.

    To conclude rapidly, I would say that you can’t claim an argumentation because you are not able to see how it is done or build but should trust the fact that most KPP parameters were exceeded in term of performances (and multi-service requirements have historically not been the more complacent!)

    By the way when you say this

    F-35 are a notch below what technology allows right now.

    You should understand all the rubbish in it: the F-35 is an incredibly manoeuvrable fighter jet that can out AoA most fighter out there including the bests known in that domain so far (the SH) while retaining full authority in yaw, something unseen until now for something without TVC.
    The F-35 is then indeed the best of what technogy has to offer when looking only at this narrow domain of BFM. So, I fail to understand your point.
