I hope you find this video interesting. It is meant to provide an overview of what led to Boeing creating the 737 MAX rather than giving a comprehensive overview of the factors leading to the two crashes and the issues with MCAS so the explanation on that is quick. If you want to learn more about that, I would suggest starting with this article: https://theaircurrent.com/aviation-safety/vestigal-design-issue-clouds-737-max-crash-investigations/

@Hualani - MCAS isn't part of the autopilot it's a form of stability augmentation which is prevalent in modern airliners more accurately it prevents the control column force required to pitch up from progressively decreasing in certain AOA regions preventing pilots from easily inducing a stall themselves.
While the MAX is often labeled as "aerodynamically unstable" it isn't and the 777 which employs Relaxed Static Stability technically IS unstable but that doesn't mean it's dangerous as is proven by its safety record
Hualani (27 days ago)
Good video, good job albeit I suspect more is at play besides MCAS alone in AOA autopilot integration systems. A330 incidents have largely remained unpublicized within US media sources, yet presenting similar if not yet fatal cockpit emergencies for more than a decade. Its an investigation waiting for broadcast from those unafraid of consequences, Id like to see ALPA take a more proactive standing. Unlikely. It seems in twenty-first century loss of life is sole instigation for thorough exposé.

I used to be a hardcore if it isn’t boeing I’m not going fan. Now? I rather fly on a Tupolev or Sukhoi... Hell, I’ll rather fly on a Comac before a Max. This is what happens when idiot MBAs make the decision to save money and slap modern engines on an airplane designed in the 1960’s. FFS, I’m no engineer but when they went from the old low bypass engines to the newer high bypass engines and had to flatten out the bottom to make them fit, you probably have hit the limits of the airframe. What’s worse is they had a great airplane, the 757, which could fit these new engines. Not only that, if you can fly a 757 you can also fly a 767. But no, let’s keep what’s basically a pterodactyl in the air.

Boeing dropped the ball here. Their only new airplane in 25 years is the 787. Everything else has just been repurposed. Engines have become so large it was clear that Boeing needed a new place to replace the 737. The max in turn reflects all the problems that come with this mistake. MCAS is designed specifically because the engines are to big for the plane, had the plane been redesigned it would never have had this issue nor even needed an MCAS system

Yes Boeing made a faulty AoA sensor, however the first accident was lion airs fault.
Explanation time, The day before the first accident they had a faulty AoA sensor and an MCAS malfunction, however there was a third person in the cockpit that day (check airman) this other person knew how to and did correct the MCAS malfunction. This should’ve been a red flag to send this plane off to lion air maintenance, this should have have been the red flag to take that plane out of service until lion air maintenance fixed the AOA sensor. However Lion air maintenance did not fix this, and that plane went down the next day because of an AOA failure that sent MCAS to believe they were in a higher pitch.

Airbus better tread lightly, for they have their share of crashes and the US can force an airworthiness review on them. Why did an Airbus insist on landing in 88, and why did a Qantas plane got over 100 passengers hurt, and the training, flt 447 , the crew did not seems to understand what a stall is and pancaked into the ocean. For anyone who is concern about the only 2 major manufacturers in the world , I suggest they try some of the even more primitive new Russian /Chinese planes coming on stream.

Airbus is a much newer company with newer products. With the exception of the A300 and A310 which aren’t made anymore, all airbus planes are fly by wire.

They made the computer too powerful, and Airbus is even worse. Boeing combined a powerful computer with a shoddy sensor, without enough testing, which is inexcusable. Once the executives responsible are in jail though, the problem has already been fixed and the 737max should fly again, But ONLY as long as the executives are in jail, and it must be grounded whenever they are free.
All the plane needs is limits on the computer trim control, a backup sensor, and an executive prison, and it had the first 2 months ago.
They also need a stretch version that trades some range for increased capacity, since carrying 4000 miles of fuel is not fuel efficient, so planes should refuel within 2000 miles whenever possible. This also allows passengers to stretch their legs, thereby reducing legroom requirements, which again increases efficiency.
Leo Rambo (18 days ago)
Your videos are really cool, but this one is kind of misleading. The 737 MAX has Hydraulic flight control actuators, and cables as redundant direct-controls, It also has a dedicated warning panel instead of a 'single warning light'. Moreover, commercial aircrafts don't have a 'one click start', all have a multistep procedure of some form. You should do more research before making a video, otherwise you are only spreading misinformation to your millions of subscribers.

All airplanes could be a deathtrap. Also not to remove the blame on Boeing but Airbus uses the same system of making their planes training as simple as it can be. The A380 cockpit is almost as similar as the A340, every aviation company dose this to reduce costs and have more orders. I personally did fly on the MAX but the media overreaction is a way too much. The B747 had 61 hull losses ( due to the poor security pre-2001, and back in the 70s/80s where plane bombings was the #1 thing that terrorists did) while The max only had 2. Southwest had 44,000K flights and had zero incidents. I will wait about 2-3 years after recertification but after that, I am back in the plane due to being a frequent traveler. Personally, I do prefer Boeing because its more comfortable and has more legroom (usually) than Airbus. Also, all corporations are meant to make profits, If it wasn't Eastern airlines an American company Airbus would have never existed.

Most people commenting here have no idea what they are saying and only taking a media perspective to shape their own opinions. It is sad that people have become so weak minded that they cannot look at the facts themselves and speak intelligently afterwards. Most refuse to waste the additional time it takes to get the right information, much less speak intelligently. It is much easier to spew hatred across the internet than facts I suppose. Boeing did offer training packages on the MCAS and other systems of the aircraft but many countries did not purchase the training. As the narrator said, this aircraft flies the same today as it did 50 years ago. American Airlines did not purchase the training and they did not crash a single aircraft. Most 1st world countries did not purchase any of the training and most did not crash an aircraft. But, there are flaws in everything man made. Nothing is perfect. Airbus had multiple issues with the A380 but no one is talking about those today. Wanna know why we have rounded windows in all aircraft today? Go ask DeHavilland how three of their jets exploded off the coast of Africa because pressurized cabins and square windows lead to stress fractures over a short period of operation. Better yet, lets ask Lockheed Martin about their C130 wing spar issues?I have a degree in Aeronautics, an A&P license, a pilots license, and a multitude of other licenses in the field of aviation. But what I have never obtained is the ability to witness false statements and hatred spewed by those who have absolutely no credentials to speak about a subject and have the ability to sit back and allow it to happen. Just sit down, shut up, and let the real engineers fix the issue.
John Smith (21 days ago)
The fact that Boeing kept redesigning and updating the 737 to be able to sell the plane on price instead of fuel efficiency wasn't what led to the crashes and grounding. Where Boeing messed up was by designing MCAS in such a way that it took all of its critical Angle Of Attack data from a single sensor. When that one sensor was defective, damaged, or frozen, it sent erroneous readings into the MCAS system, which ordered the plane to go nose-down to "correct" a stall condition that was not actually happening. Depending on one sensor created a "single point of failure", which is a design flaw that good "belt and suspenders" engineers avoid. Two independent sensors feeding the MCAS and a warning signal to pilots that that the sensors aren't agreeing would be better. Three independent sensors feeding a logic circuit that disregards a sensor that is not in agreement with the other two and "assumes" the two that agree are correct, doesn't feed the bad sensor's bad data to MCAS, AND warns pilots of the sensor issue is probably what SHOULD have been designed in the first place, but some non-engineering middle manager came up with a cheaper idea on behalf of Boeing's shareholders.

- A220 sales rise, and A220 becomes world's most popular single aisle. (As of today, airlines and passengers already love it.)
- Chinese Comac gets a real chance to enter the aircraft market.
- Project Sunrise chooses A350 to fly non stop from London to Sydney
- Dreamliner and Embraer become crucial for Boeing's Survival.
- Lockheed buys Boeing (or part of it) and becomes world's biggest aircraft manufacturer.
- New regional aircraft manufacturers enter the market.

The age of the original 737 design is irrelevant. The original 747 design is also 50 years old. The 747 has also seen design adjustments over the years.
Airplane design has been evolutionary. Even when the design is "new," it is based on what has been learned from older models. Almost no commercial airliners have been radical departures from the past. They feature incremental improvements.
Also, overhauling existing plane is a common maintenance practice.

Stupid question: Why was the size of the new engine such a big problem? Why couldn't Boeing just increase the height of the gear. Was it the additional weight or does a longer gear require retraining of pilots?
E1craZ4life (1 month ago)
compuholic82 On most airplanes, the main landing gear folds inward when it retracts. In the case of the 737, the gear is so close together that there’s no space for doors to cover the gear, so they just have hubcaps that form a flush surface with the plane’s underside. If the main gear was made longer, the struts would have to be spaced further apart to avoid hitting each other, and if they did that, they’d also need to redesign the wing to accommodate the bigger wheel well as well as the change in weight distribution.

James Shanks (1 month ago)
Why did Boeing add the mcas system if it already has an autopilot system and two pilots? The way I see it Boeing needs to bite the bullet and redesign the 737 max to not have an mcas system on board the aircraft. This requires a completely new aircraft design. Yes, I realize it would take a few years but the aircraft isn't flying and needs a redesign.
Also screw the cost of pilot training and don't even suggest an iPad can train a pilot. Otherwise I could download the program and fly one myself. That would never happen as I haven't flown an airplane in over 48 years. I wouldn't accept the training which is where I believe your looking at better than 99 percent of all commercial ata rated pilots today.
Training by iPad to cut cost of training , how much money has Boeing and the airlines saved?
Time to face facts that the 737 Max needs a redesign from nose to tail, lengthen the landing gear to get it off the ground and put the engines back where they belong, under the wings, not in front of it.
Gentlemen, you know how to fix it. Do it right with a redesigned aircraft. Then and only then will you be able to put a safe 737 Max in the air loaded with passengers who trust it.
Get it done.

Roscoe (1 month ago)
To be fair if the Max was done properly, and that includes the FAA approval, it wouldn't have those issues. It is possible and viable for boeing to redesign the old 737 into a more efficient one. Its just mistake after mistake during engineering, production, approval, training and flying that caused lives to be lost. Every single fail prevention system that exists in aviation failed, its a huge embarassment for boeing and every single organization that certified the 737 max plane as airworthy. At least in aviation they tend to investigate thoroughly and put new measures to assure something like this won't happen again.

Daniel Moolman (1 month ago)
You forgot a big point, brought up in Vox's similar video. Before the max, Airbus decided to make the A320 Neo, which is identical to regular A320s but have larger and more efficient engines. Boeing followed suit to remain competitive, but there was one giant flaw: 737s are much lower than A320s, and therefor couldn't fit the new engines. This made them put the engines further forward, which resulted in the plane slowly angling upwards. This made them put in the disastrous system, but they didn't tell the pilots about it as the whole point of the plane was to be pilot-compatible. All they had was a two hour coarse which didn't even mention it.
