Goldfein: Air Force still looking for ‘smoking gun’ causing hypoxia problems
Since Hypocania is the new black in military aviation, you can read more on it here on Wiki
Even when marked, hypocapnia is normally well tolerated.[1] However, hypocapnia causes cerebral vasoconstriction, leading to cerebral hypoxia and this can cause transient dizziness, visual disturbances, and anxiety. A low partial pressure of carbon dioxide in the blood also causes alkalosis (because CO2 is acidic in solution), leading to lowered plasma calcium ions and increased nerve and muscle excitability. This explains the other common symptoms of hyperventilation —pins and needles, muscle cramps and tetany in the extremities, especially hands and feet.[citation needed]
Because the brain stem regulates breathing by monitoring the level of blood CO2 instead of O2, hypocapnia can suppress breathing to the point of blackout from cerebral hypoxia.[citation needed]
Hypocapnia also results in bronchoconstriction in order to decrease ventilation. This mechanism is meant to counteract hyperventilation, and decrease the amount of oxygen coming into the lungs. The body’s “goal” is to have a relatively even ratio of the partial pressure of oxygen to the partial pressure of carbon dioxide. Chemoreceptors in the body sense a change in partial pressures and pH (hydrogen ion concentration) in the blood. Chemoreceptors are responsible for signaling vasoconstriction, vasodilation, bronchoconstriction, and bronchodilation.[citation needed]

Japan seeks role in French-German marine surveillance plane project: sources
Discussion between the three governments began last year. Japanese officials also asked Kawasaki Heavy Industries, which makes the P-1, to discuss possible partnerships with France’s Dassault Aviation and Thales SA, said the sources, who have direct knowledge of the proposal but are not authorized to speak to the media.
“If they try and build it from scratch it will cost a lot and their potential market is small, even if Spain or other European countries buy it,” one of the sources said of the European project.

Russia Widens EW War, ‘Disabling’ EC-130s In Syria
The Compass Call is supposed to be one of America’s foremost electronic warfare weapons, but the EC-130s flying near Syria are being attacked and disabled “in the most aggressive EW environment on the planet,” the head of Special Operations Command said here today.
“Right now in Syria we are operating in the most aggressive EW environment on the planet from our adversaries. They are testing us everyday, knocking our communications down, disabling our EC-130s, etcetera,” Gen. Raymond Thomas told an audience of some 2,000 intelligence professionals.
[…]
[Russians] may have taken the much easier route of interfering with the Position, Navigation and Timing (PNT) or their communications gear, making it more difficult to fly the aircraft since crews would have had to rely on maps, line of sight and other techniques.
“The problem the EC-130s have is that, while they are jamming, the crews aren’t doing much else,” making them more vulnerable to attacks, she says. “They could have gone after the PNT or the comms.” The Russians “know all of our vulnerabilities.”

Germany, France agree main needs of new joint fighter program
Germany and France have agreed on the central requirements for a new fighter jet to replace Eurofighter Typhoon and Rafale warplanes beginning in 2040, German military sources said.
This will kick start a program first launched in July last year and officials from the two countries will sign an outline document on the sidelines of the ILA Berlin Air Show, which will be opened on Wednesday by German Chancellor Angela Merkel.
[…]
The statement of political intent is expected to be followed by an industrial declaration that sets out in more detail how the partners, notably Dassault Aviation and Airbus, Germany’s defense aeronautics champion and a Eurofighter consortium member, will approach the multibillion-euro project for which Dassault has made a strong pitch to be senior partner.
(Definitively, there is room for the Lightning).
More details in an Airbus CEO interview from yesterday (Bloomberg):
Airbus’s German operation is working with French warplane specialist Dassault Aviation SA on a fighter platform involving a range of aerial products, including drones and “swarms” of small aircraft, Enders said […].
“We’re not talking about ‘a’ military aircraft,” he said in Berlin. “We’re talking about a system of military-combat airborne elements. It’s a different system.” It’s not even clear whether there will be role for a piloted plane, the CEO added, saying that depends on requirements specified by the French and German governments.

Germany just added some UAV with dual capability. The persistence requirement (sea and out of area) might be then fielded already.
Sikorsky modifies Raider helicopter to use [ITEP,] US Army’s future engine
Raider will be able to accept either one or two of the Improved Turbine Engine Program engines from the start, which will also help support bringing ITEP to fruition, Chris Van Buiten, the company’s vice president of technology and innovation, told Defense News in an interview.
“The engine in Raider is just a beautiful match,” he said.
The Army is said to be on track to award a contract to one of two teams currently developing a future helicopter engine in late 2018.

I invite you to search all the meaning of the verb to lie.
Then take the time to remember all that decade of harsh diatribe around “Stealth is overrated”, “5th generation is a myth” etc… Not that I think you are complete stranger to that 😉
So, it’s not my opinion. It’s a matter of facts:
a castel of words and short sighted opinions
“As soon as Germany becomes an F-35 nation, cooperation on all combat aircraft issues with France is dead,” Dirk Hoke, the CEO of Airbus Defense and Space at Airbus Group, told Welt am Sonntag newspaper.
“Europe needs to define its sovereignty more clearly and state that we need to remain independent in defense and space,” Hoke said, referring to the joint Franco-German project to develop a fifth-generation fighter, according to the newspaper.
Interestingly we had the same charge from Dassault’s CEO lately in front of French parlement. It seems then that the main credence for the future Franco-German fighters lies in a castel of words and short sighted opinions*.

*France and Germany are NOT constituting Europe by themselves
The French and German doctrines are miles apart: while the French have used their Atlantique in a very offensive roles (they spent a lot of time over Mali dropping LGB) and have the largest Exclusive Economic Zone on the planet (need a long range plane able to operate with minimal cover), the Germans need to patrol a territory the size of a napkin
We agree on that. I mentioned this fact earlier on page2
(transplanted here)
the point is that the F-22 isn’t produced anymore anywhere. Taking the airframe as a base to customize a fighter specific to Japan needs will de-facto not impair their own industry.
Fielding the 22 as the source airframe could be a guarantee to leave aside a lot of the inherent cost of a new design (think airframe, stealth. weapon integration…) while sticking to the expectations of Japan in term of greater range. Then, Japanese designed engines and systems can be fielded etc.. This might even include the UK industry.
Think Kfir and Cheetahs.
The P-8 and P-3 put in perspective as a case of study (Source: FoxtrotAlpha 2014): Confessions Of A US Navy P-3 Orion Maritime Patrol Pilot
nothing says the contrary. The point is to base your design on an airframe that have suitable characteristics. Nothing stated beyond that point.
But obviously, this englobes potential realistic (hence must be expected) emergency situation. I am not sure who mentioned anything like barrel [t]rolling.
Box 35S to be searched next week
One source close to the investigation says only one of the five auto pilot settings — constant magnetic heading (CMH) — would lead to a crash site at 35S, where the ocean current at the time ran in the opposite direction, towards Africa.
Box 35S is close (West) to where French satellite imagery came from (the ones that were not reviewed for years –read here)
French satellite images first seen in March 2014, a week or so after the plane disappeared, showed white objects in this same area, at 35S.
At the time the objects were dismissed as unimportant.
[…]
The drift analysis included retrospective calculations to gauge where the objects might have been in the hours after MH370 disappeared. And sure enough, it was around 35S, the new zone where Ocean Infinity is preparing to search.
EDIT:
Latest update from Ocean Infinity report:
Search to be interrupted at the end of April for crew change (and weather).
Report 042418
EDIT (as of 050118):
Oliver Plunkett, Ocean Infinity’s CEO: As the team head in to port after another six weeks’ hard work, I am pleased to say our technology has performed exceptionally well throughout the search and that we have collected significant amounts of high quality data in which we have full confidence. The results from the highly challenging Broken Ridge feature are particularly impressive.
Whilst it’s disappointing there has been no sign of MH370 in the Australian Transport Safety Bureau search area and further north, there is still some search time remaining. Everyone at Ocean Infinity remains absolutely determined for the remainder of the search.”
