I have an upcoming long-distance flight and this kind of stuff scares me, despite knowing that air travel is usually very safe.

I suspect a failure of the stick pusher. The stick pusher is a system that when an aerodynamic stall is detected it manually forces the nose down and is difficult to overpower. You can deactivate it but finding the switch quickly is no easy task.

Ethiopian is relatively safe by African standards, but outside of a couple of the major carriers (Tunisian, Royal Air Maroc, South African) you're taking your life in your hands when you board an airliner in Africa. Many of them are not even permitted in European airspace.
The 737 is one of, if not the most popular airliners ever. The 8-Max is a next generation iteration of the type with many modifications, but I'd be surprised if it came down to equipment failure or malfunction.

My first thought too. That was also partially the cause of the recent LionAir crash. Will be interesting how Boeing will handle it. They might have to ground the MAX fleet until they can provide a fix.

The plane was almost brand new. Let's wait to see who was on board. Maybe someone was interested in having that plane down.

This hits home for me. I had family at airports in the vicinity. I think Boeing has been somewhat lax in their response to the Lion Air crash. I fly Southwest quite a bit, they have some in their fleet. I'm also flying on an international flight on the MAX 8... oh boy.

Tiger, the key to a safe flight is to NOT BE NERVOUS. The vibes from nervous passengers can create a small resonance that can suddenly grow and build up critical stress in the aluminum structure of the cabin, resulting in catastrophic failure. Try not to think about it, and once again, DON'T BE NERVOUS. The worse that can happen to you is to survive a crash over the ocean, where you would die in agony from a combination of your injuries, hypothermia, and gradual dismemberment from hungry sharks. But chances are, if there is a midair crash, you will probably die on the spot, so you don't have to worry too much about the worst case scenario where you're barely floating in the cold dark waters getting torn apart.
So once again, DON'T BE NERVOUS and you'll be OK. After all, you and I know that air travel is very safe, USUALLY.

I only have a few hours in the Max but I have several thousand hours in other 737 variants. I'm currently inactive so I haven't been briefed on the results of the Lion Air investigation. Having said that, my best guess is that there was an equipment malfunction that may have been mishandled by the pilots. The max has a trim compensating system that is slightly different to the other models but if it goes awry it's easily handled by an experienced crew. You should feel very safe flying in a 737 in N America and W Europe (and Japan, according to some of my friends). Other parts of the world have different standards.

There's no way that two identical tragedies in such a short period of time are the airlines' fault. I will make sure to avoid flying with any Boeing 737-800 model in the future. RIP poor passengers.

Apparently the Lion Air one was related to the angle of attack sensor:wrong information generated spurious signals to incorrectly retrim the horizontal stabilizer, is what I'm told.
Not sure if this is an issue that would extend to the whole fleet or just a problem with that one aircraft.

2 planes of the same model going down in similar circumstances. Yeah I'm sure those planes are not going anywhere until they've found out why. They dont want a third. I'm sure the PR department for Boeing is saying everything is fine but behind the scenes they are probably scrambling to find out if it is a big fuck up on the software side.

Standards for avionic product qualification are very high. But from a statistical standpoint, you can't test a complete new airplane model to full six sigma extent.
So what is left, is to construct the plane in a way that the plane and it's parts and subsystems are statistically safe. Subsystems you can test to death with accelerated test conditions. The final confirmation of a correct calculation for the whole plane would only come after deploying the airplane.
I guess, Boeing can't build 100 or 1000 new planes just for qualification of a new model, and let all of them land a 1000 times.
Quite sure Boeing and Airbus always assemble a team of engineers to do a in-depth analysis of what happened, if the crash wasn't suicide by plane crash.
The engineers most familiar with the new MAX model won't have a relaxed time the coming months.

Don't you worry, guys, the Boeing MAX is safe.
It happens the plane was shoot down, electronically hijacked or brought down in whatever way someone wanted to. It happens that
the United Nations had at least 19 officials on the Ethiopian Airlines plane that crashed Sunday morning, some of whom were en route to a major environmental conference in Nairobi, Kenya.
I told you so.

Here's the real conspiracy:
China has deliberately taken the lead in grounding them not because of a genuine belief in a safety issue, but because it's an easy headshot in the trade war. Escalate the scare and force airlines worldwide to follow suit or else look like they don't take safety seriously.
...
Yeah that makes sense. That's one of those stories you start to read and know right where it's going.

That sucks. Fly Dubai uses the 800's to and from Africa and Afghanistan. Hopefully their pilots are more experienced than some of these others.
With the pilot shortage worldwide, companies are hiring pilots with 0 turbine time. Some of the emerging countries are getting fresh pilots because they can't hold on to theirs. The big boys feed off the little companies like the regionals feed the legacy carriers here in the USA.
More and more countries are grounding their 800 max planes. I've read about 2 others so far. The feds are in deep with Boeing. I read of secretary of defense did 30+ years with the company. Dont expect the FAA to do anything soon.
I think 3 is a trend. I think the western world has more experienced pilots and better training. We should be straight.
The cycle of disrespect can start with just an appetizer.
