      Brad W I wasn’t inferring the 73 had a pusher. Only using that as a ‘standard’ stall prevention term in reference that the MCAS was not a stall prevention tool. I apologize for the misunderstanding. However, the MCAS is ONLY there to create the same feel as the NG due to the higher pickup tendencies from a more forward (not up) and higher thrust engines, thus differences training is only required and not a different type.

      can various *governments* of all countries wherever these coffins were supplied not file en-masse lawsuits? or similar to class action suits which they have in Divided States of Murica? the certifying and monitoring bodies, be it FDA or pharma industry bodies, are all sold out, lethargic or corrupt and incompetent. Bringing them to book or making them change their ways is important too.

    I wish this video would come out later then it did. There is new updated information about exactly what happened in flight. This video is not wrong but is not fully correct. Upon further investigation: 1. It was found there was a bird strike (something hit the airplane on takeoff) on the AOA sensor on the Ethiopian flight. This caused false readings on the sensor which had an effect on the crash.2. Yes the MCAS took over and forced the airplane down.3. The new report shows the pilots followed the check list and turned the system off. However, after regaining some type of control they turned the system back on. Which later unfortunately the plane crashed. Unlike Lion Air, there was multiple factors that brought this plane down. I study and work on many aircraft. I'm a fan of your videos but I believe this video should have been released after a full report has been done.

    This doesn't make any sense whatsoever. How does moving the engines up cause the nose to pitch up? Shouldn't it cause the nose to pitch down? You've moving the center of thrust higher up relative to the center of mass. That should cause the nose to pitch *down*, not up.

    It's like not being able to shut down the cruise control in your car! How stupid is that? Yet that happened to the Boeing 737 Max. Even my car has several fail-safe mechanisms when I use the cruise control. It de-activates when I use my brake, when I change gear or when I press the cruise control Pause button. Moronic Boeing.

    Mitchell Kirkwood: This is not an issue of how pilots reacted to a poor design that appears to be the opposite of fail-safe in my opinion. Nor is it a software issue. This is a fundamental aerodynamics issue. But lets suppose this is a pilot training issue for argument's sake: Do you want to fly on an aircraft where missing a switch (in reality its a series of actions) right after takeoff and at low altitude, during one of the most critical stages of flight where there is little margin for error, causes everyone onboard to die? And do you want to trust a manufacturer that would approve a design like this? I've been a life-long Boeing fan up to this point by the way.

    Ryan Aegis: This is not a simple "under-the-wing" engine design behavior as you have stated. There is likely a more complicated set of aerodynamic problems including a canard effect that were introduced with the re-engine on the Max, and that are causing the abnormal level of pitch up on takeoff and stall recovery. I think the effects are explained well here:

    Nicely made however it puts boeing at the total reason for the crash which is not the case the M Cas system Indeed Got misinformation from the left sensor outside of the aircraft which made it thank it was going in and up position while the left sensor or Wind vane showed the proper angle of Attack. When M Cass kept Making the elevator go up in position at so many degrees for 10 secondsIt it made it act just like the original 737 run away trim so the procedure to fix both were the same in turning off the cut out switches.The 2nd Max 8 Crash indeed had this problem but the pilots made two errors.. The 1st one was they failed to watch their air speed Which climbed just below the speed of sound and way past The aircraft tolerance and NEVER reduced power keeping it in takeoff position. When they correctly switched off the M Cas system (cutoff switches, The aircraft was going so fast when they tried to trim the elevator from the top position to the middle position The forces on the elevator were so great that they could not turn the wheel by hand Except very slowly so the pilot used the electric trim but after a few seconds stopped and then again try to by hand then they did not follow checklist procedure which said do not turn the M cas system AKA cut off switches back on for any reason, for this would re introduce an instant downward Characteristic which the pilot did they were close to bringing the plane backup when they turned it on and this nose dived it into the ground.

    Look I'm know expert. But it's clear that it know software issue but rather more of a design flaw. You can clearly see that those engines above the wing cause way to much drag for the plane to fly correctly. Meaning to much drag with minimal pilot training can and will result in a bad outcome. All those souls just to push product out into the market is murder, plain and simple and Boeing should be held accountable for there foolish actions.

    All under-the-wing engines force the nose up during acceleration, just like over-the-wing engines force the nose down during acceleration. And this is something pilots are trained for. And, actually, moving the engines up higher put the engines closer to the centerline, which would make them push the nose up less than the same engine slung lower below the wing a la Airbus. The difference, besides size, mass, thrust, and efficiency, is that the new engines had to be moved further forward to be raised higher, which makes the fulcrum different, and thus, the plane handles differently. Is Boeing to blame for this design? No. It is not a bad design at all. Are they to blame for the lack of pilot training? No, that is on the airlines for not providing the training or on the pilots for not reading it. Especially after the Lion Air flight went down. Are engine failures to blame on Boeing? No, the engine is made by a third party and fixed to a Boeing aircraft, and maintained by the airline. MCAS is not new, just a name people are now learning. Anti-stall software has been around, and pilots have been trained how to handle a malfunctioning system. If anything, I blame the pilots for not reporting the problems more aggressively, their higher-up's for not fixing the issue sooner, and the pilots who do not know how to fly a plane without computer assistance. And even a novice pilot should know that, when the computer is flying the plane wrong, turn the computer off.

    You need to also address how cultural differences were also a contributing factor. Many pilots in other countries are severely restricted on their latitude to take any initiative. If they do anything outside of their training, they fear for their job. American pilots on the other hand will say 'f**k this s**t and shut of the autopilot and fly the damn plane. You are WAY understating the scope of the problem when you say 'few' US pilots reported the issue.

    What you failed to mention is that the first officers on board of both flights were massively undertrained in flying period. Not just in the flight systems. Many southwest pilots experienced the same mcas problems but they were trained in the system and were able to turn the system off before anything crazy happened. Any good pilot knows not to let the plane get into over controlling oscillations like that shown in the graph. The problem starts when you try to manually fight the autotrim and get into those oscillations. The solution is as simple as flipping a switch and manually flying the plane. Boeing is only partly to blame. In my eyes the inexperienced pilots from countries with low ATP requirements should be mostly to blame

      phosfanian devil This is not a training issue or a software issue; it’s a fundamental aerodynamics issue. But let’s say for the sake of argument that this is a training issue. Would you want to fly on an aircraft with such a precarious design that missing one switch (and in reality it’s not one switch - it’s a series of repeated actions) immediately after an abnormal situation right after takeoff (low altitude) causes everyone onboard to die?

I would not worry about the max in America because when this issue came about the pilot went on strike and said they would not fly the 737 Max 8 until proper training was given. Because they ran into the same issue. I'm not sure of the country are unionized. What are the airline companies I refusing to make sure their pilots are properly trained.

    It's all about the money for Boeing, passengers lives and safety a mere after thought. They were just trying to save money by not having to re-badge and re-certify a new airframe design, which would have cost them millions. So Boeing said hey, let's just cram these large engines (that don't fit) under the wings and call it good. I have a jet aircraft maintenance background, moving the engines forward and upright to make them fit under the wings was a really really bad idea, basically unbalancing the lift dynamics of the aircraft thus causing the plane to nose up into a stall under full throttle. And relying on software and sensors to fix the problem was a terrible terrible ideal by Boeing. I'm sure the pilots were desperately fighting the computers taking over the flight controls (malfunctioning) until they ultimately crashed and died. Shame on Boeing.
