    We know little about the truth. Calling japanes air force stupid is a bit early dont you think?

      Where in my post did I call the Japanese air force stupid? And voices in your head doesn't count.

      If reports are true that this F-35 had a couple of issues but they decided to keep flying that is not smart.

        Here is a question I asked on another forum. Does anyone know if any other F-35As flu since the Japanese crash? Im asking about F-35 version A only anywhere in the world.

          Not sure, but only the Japanese announced a hold on flight ops.

            If no other F-35A flu lets say since the crash, it would be unofficial grounding and would point directly to discovery of a new problem that affects all. If any other F-35A flew since the crash, than its a completely different thing, and could be related to isolated incident or Japanese factory error only.

              I think everybody is leaning in that direction. The fact that no general grounding was issued being a strong indicator. Don't forget that Japan seems to have been aware of some (at least in the earlier model) difficulties with their line. I take that from granted since Italy didn't apparently face any similar concerns , while having produced both A and the more complex (?) B models.
              So, it would seems logical IMOHO that only the Japanese fleet is grounded. But let's wait and see.

                It is very common for an Air Force to ground aircraft after a crash by another operator. It is simply a precautionary measure and does not point to a new problem that effects all aircraft. There are a host of issues that could have caused this crash and an F-35 airframe issue is only a small subset of the potential causes. Let's wait until we know more before making claims for which there is no evidence to support.

                      Whatever happen did so quickly. So, the pilot maybe still with the aircraft. So, when they locate the missing F-35. I wouldn't be surprised if they find the pilot too.

                        Honestly think its a bit of a misstatement. Its a high alpha maneuver not unlike a pirouette or herbst ( more accurately J-turn).The aircraft goes to high alpha and slides the nose around, the whole time from onset to completion is more that 3 sec if you watch videos of the turn.

                        Hugly impressive, but like those other maneuvers, it likely requires airspeed in the 200-300 knots range.

                          One thing Im sure of is that there have been many more F-35s out there over the years that had emergency landings that were not reported. Any imperfection can result to a safe course of action which can be called emergency landing, specially during the first few years of entering service. I wouldn't take this as a sign of why this one fell and other three did not.
                          very doubtful, there is a protocol for reporting emergencies and mishaps and it is not open to interpretation. Every single incident reported by a pilot is reported to authorities. It the issue requires emergency procedure, it would be reported.

                          Took a lot of hard lessons to come to that system.

                            It is not a turn, but a rotate. turning is when your velocity vector changed ist direction. plus and minus AoA btw.

                              Yep but whatever it takes to get into that 90 degree aim-9x hemisphere as quick as possible though.

                              The principle of the f-35 is that it'll get the first shot on you in most scenarios, but even if you make the merge you're still in trouble at the first turn. It only needs to keep the initiative until team mates arrive (f-35 is more likely to get reinforcements earlyein a fight) and snipe you from range with amraams.

                              I'm struggling to find videos of other aircraft that do these high aoa turns at f-22 and f-35 speeds. Rafale just doesn't seem to do it (delta), and even the Su-35 seems to struggle at moderate speed. It usually only seems to do a decent instantaneous turn at almost 0 velocity.

                                Different type of maneuvrability it is as simple as that.

                                Rafale/F16/Typhoon may not reach those extreme AoA but on the other hand they will preserve their energy much better. It is much more a software limitation than a physical limitation. There are pro and cons both ways...It is really an endless debate, any outcome (everything else being equal) will depend on tactics and pilot skills. High AoA is fine but if you miss your shot you have bled all your energy...You can still retain some marginal post stall maneuvrability but you will be in not so enviable position falling like a brick trying to point your nose somewhere. This tactic can work...Or fail...There is just no guarantee !

                                As far as IR missile are concerned, one can make the case that a MICA IR which has "roughly" the range of an AIM-120C5 could be shot long before the merge (it has a datalink) in case your EM missile fails...Due to jamming for instance, which is a likely scenario.
                                So all that's maneuvrability/HMS/HOBS story is suddenly not so relevant when you have a "long stick" IR missile. The truth is that even a mig 21 with a modern HOBS/all aspect IR missile with HMS has about the same chance than an F35 or F22 in a dogfight.

                                  Fortunately the F-35 in particular recovers energy extremely quickly. Not sure if you've ever seen it at an airshow, but after performing energy bleeding maneuvers it accelerates faster than most aircraft I've seen, including the f-22.

                                  With the first shot advantage, fast initiali turn, energy recovery, 360* engagement with amraams where needed and the superior field of view with the aim-9x sensors it's chances are significantly better than the mig-21 or any other fighter in the world for that matter.

                                    Rafale and un-magic wedged Typhoon don't reach even Eagle's AoA value. Point Barre*.

                                      And you saw this where, At some Airshow?
                                      Where it did a High AoA turn(the mighty J-turn!!!!!) oh i'm totally sold and then recovered in a straight line
                                      A somewhat hilarious flipflop from what you guys has been saying for the last decade now about Flankers at Airshows.. its just for airshows.

                                      Good luck recovering energy in a straight line, when you got someone on your six. Ouch!

                                          Air Force's F-35A Deploys to Middle East for First Time

                                          The U.S. Air Force's F-35A variant has officially deployed to the Middle East.

                                          Air Forces Central Command announced Monday that F-35 fifth-generation fighters from the 388th and 419th Fighter Wings at Hill Air Force Base, Utah, have deployed to Al Dhafra Air Base, United Arab Emirates to keep watch in the region.

                                          It's the first time Air Force F-35s have deployed to the Middle East.
