    Quite a long press conference from Australia, on CNN this morning.
    Detailing the next phase of the search operation.

    MH370 likely on autopilot with unresponsive crew in flight’s final stage

    They are moving toward the theories we discussed earlier.

    Australian authorities suggested that Flight 370’s crew may have been in an “unresponsive” state, possibly caused by a lack of oxygen.
    That scenario “appeared to best fit the available evidence for the final period of MH370’s flight,” the report said, citing previous air accidents in which crews had been rendered unresponsive by a lack of oxygen, also known as hypoxia.
    But it cautioned that the assumption was “made for the purposes of defining a search area and there is no suggestion that the investigation authority will make similar assumptions.”

    One remark:

    The cockpit and cabin are not hermetically sealed. That means that there was a contamination from one of the volumes to the other. The way that contamination spread is the route toward an explanation of the incident. Whatever that contamination was (loss of pressure, fumes, Li battery gases, criminal act…).

    Last but not least, it’s now reasonable to think that some or a few of the passengers might have survived until the very last second of the aircraft. I hope that everybody interested by solving this enigma for the only sake of public transportation safety will keep that hypothesis in mind.

    NDIA Official: DoD’s Red Tape Could Become ‘Most Dangerous Enemy’ to US

    “Program officials with long terms of office understand that they will still be in office years from now, and consequently that they will be held personally accountable for the results of decisions they make, at least those they make during their earlier years in office.

    “By contrast, officials with shorter terms of office face less risk of being held personally accountable for the results of their decisions, because those results may not become manifest until after their terms in office are complete,” O’Rourke said. “Indeed, they might even feel an incentive to make decisions that achieve what they view as near-term success for a program — such as getting a program started — even if those decisions increase the program’s risk of experiencing execution problems later.”

    Excellent article. A must to read

    […]

    They have promised action haven’t they? US aircraft flying alongside Iran and Syria. So, next we need the Russians to get involved overtly and then the whole world will be on it’s head.

    Where are the RAF, the FrAF, the NATO or the UN ? […]: that is the question and blablabla

    Whatever, there is a positive trend in all this.

    I wish I cared enough to make an F-16.net account to laugh at them.

    But seriously, not a good week for 5th gens. China better have those fire extinguishers ready.

    yes. Enough to make your paranoia index surges.

    No the Delta’s are here to help makes a fighter landing at slow speed and still achieve supersonic regime.

    If you want to lower wave drag, you lower thickness ratio and curvature :

    In the 40’s:
    – Symetrical and biconvex

    In the 50’s:
    -> the thin strait wing theory
    -> the Delta trick
    -> swept (wing thicker)

    -In the 60’s
    -> Canard thin Delta
    -> Advanced BL ctrl + Thin Wing
    -> Advanced BL ctrl + Swept Thinner Wing

    -In the 70’s
    -> Advanced wave drag management + thicker wing + staggered wing/tailplane
    -> thin swept wings
    -> VG wing

    – In the 80’s
    -> Active Canard + thicker delta
    -> Thin wing + fuselage lift + advanced CFD simulation
    -> FSW

    In the 90’s- 2000’s
    -> Active BL ctrl (fluidics)
    -> Blended Fuselage/Wing or Flying Wing

    In the 2020
    -> Active BL ctrl (Plasma)
    -> Flying wing with (enhanced) MassFlow ctrl (beta)
    -> Overall shape enhanced for propulsion
    -> ???

    If you take a look at statistics of all air-to-air engagements to date, you will see that vast majority of kills were within visual range regardless of weapon used.[…]

    The majority of A2A kills were WVR simply because in 99% of cases in your sample there was no other means to kill. I might have misunderstood you but what your wrote equates saying that you’d need to be behind a propeller and wear a white scarf to score a kill 😉

    [ATTACH=CONFIG]229464[/ATTACH]NO White scraf (and no prop)!

    You can only compare BVR and WVR when both were achievable (tech, RoE, weather…). Otherwise you can’t make any conclusion.

    As of today, 23rd June 2014, Syria has shipped out its last ‘declared’ chemical weapon. Removal of Chemical Weapons From Syria Is Completed.

    On Monday in The Hague, OPCW Director-General Ahmet Üzümcü praised the final removal of the chemicals from Syrian turf. “A major landmark in this mission has been reached today,” Mr. Üzümcü said. “There were expected and unexpected challenges along the way, but the OPCW and the member states have been able to overcome them.”

    It’s all about interpretation. One could say the F-35 and F-22 demonstrate his conclusions.

    It’s always bad to focus on the error of any individual, especially when marketing and public exposure makes them turn their arguments into a posture.

    Great men are wrong and right. All of them. No exceptions.

    A Luftwaffe Eurofighter collided with a German GFD Learjet this Monday afternoon the 23rd of June.
    By the looks of it at
    http://forum.scramble.nl/viewtopic.php?f=48&t=107031
    both Learjet occumpants probably didn’t stand a chance… :apologetic:

    On the BBC

    The incident happened during an exercise with another Eurofighter, German media say.

    Die Welt news website says the Learjet was also taking part in the exercise.

    Iranian President Hassan Rouhani criticized oil-rich Sunni Gulf states that he said were funding “terrorists” – a reference to the likes of Saudi Arabia and Qatar which have backed Sunni rebels against Syria’s Iranian-backed leader, Bashar al-Assad.

    Maliki has accused both Saudi Arabia and Qatar of directly supporting the group

    A French government official said, indicating the jet may have its first export contract. […] The topic will be discussed when Qatar ruler Sheikh Tamim Bin Hamad Al Thani visits France next week, as negotiations continue. The Qatari Ministry of Defense and Dassault Aviation had no comment… […]

    I’ll just put all this here like this as a simple draft. Feel free to comment as needed

    Seems like Austria will replace their airforce with Hungarian Gripen C… http://kurier.at/chronik/oesterreich/ungarische-gripen-sollen-wien-sichern/71.253.890

    😀

    For the Euro-Fighter flight operations is already threatening to lead the land forces into bankruptcy. A flight hour costs at least 70,000 euros.

    ???!!!

    I think the solution will be a ejector version of Brimstone because it’s also needed for the F-35B to allow for internal carriage. It also seems like the simplest solution.

    Yes. Obviously. The “How to do” in my conclusions were harshly put together. And irrelevant for most.

    Anyhow a stealthy cheap pod for the 21st century version of the rugged rocket launcher.

    One thing that the B2 success told us is that this is absolutely NOT true.

    Currently 18 Brimstone using each of the 3 inner wing pylons but a common launcher is being explored for Brimstone II and SPEAR 3, so we may see an ejector launched Brimstone carried in quad racks, which would also suit F-35B internal carriage.

    http://www.adsadvance.co.uk/bae-systems-awarded-brimstone-2-onto-typhoon-study-contract.html

    The missiles are 50kg each and the triple rail launcher is 90kg, so all-up weight for a triple mount is 240kg (530lb), making it roughly equivalent in weight to a single Paveway IV.

    I was also thinking that a 2,000lb JDAM/LJDAM(-ER) would go nicely on the inner wing pylon being roughly similar in length to an EPW II and narrower.

    I don’t understand what they don’t design a commune launcher like a stealthy pod for the Brimstone. All said that it will stay a commercial success for long and adapted to platform with RCS reduction shape and increased Dyn perf req. for the carrier.

    Something where the studies for the StormShadow family of missile could be reused to lower the cost.

    – A rotary launcher (that does not have to be cylindrical)
    – with a gravity released system at the back
    – a forward single launch tube for ex. with rotating eyelid (see the T50 canon)
    – Conformal mounted low cost sensor as an option to help widening the nbr of platform

    Eventually, it could even state the standard in dimensions or could be reusable for other missile.
