Similar to Dave!s suggestion, here is a good article about EgyptAir 990 showing the shockingly disparate ways different cultures handle airline safety.
Wow - that is quite the read. And not one word in that article about the Egyptians refusing to accept any fault with their pilot is a surprise. Egyptians are brought up to avoid blame - or rather, getting into trouble - from a very early age. I've had bigger fights with Egyptian contractors, for example, than anyone else simply because they see nothing wrong in lying to cover up their mistakes, and when called out on it, just shrug and go wha'eva.

I read somewhere that the MCAS system could be pretty flawed, in implementation.
There are two independent systems each with it's own angle of attack sensor (singular) if the sensor fails or gives a odd input to the system it can cause a major issue. Usually sensors are grouped in 3's so that if one fails a voting system disregards the failed sensor's input and uses the correct reading from the other two.
Of course you can turn off MCAS if you are trained to do this and recognise that the system is malfunctioning (but I also read that grandfather type approval had left pilots short of training on the MCAS and how to deactivate it).
Also an option to MCAS is to have the AOA from each MCAS displayed in the cockpit (only some airlines paid for this option) so you can see what each input is and determine if one is incorrect (pilots would also need the above training).
Not going to judge yet but just adding what I'd read.
Carl.

I love this place.
An *actual pilot* summed it up pretty well, and yet here we are still.

I know Ian's an actual pilot (I can't remember what type(s) he's rated on) but I'm pretty certain he's wrong about MCAS on the 737NG. I mean, Boeing say it was a new feature on the MAX...

There's a pretty big difference in flying them and building them. Pilots won't be involved in designing the redundancy systems they only get to see the outputs from them in the cockpit.
One mate who is a pilot isn't an engineer, he literally flys the a320 (for a low cost carrier), another was with me in the college course where we learnt engineering so he has a background only, hes now a ba captain. Neither will claim to understand systems design though.
Edit: just checked up on my mate and he's now instructing on the a320. Having left ba last year.

This is one of those comforting statements that makes me sink down in my chair a bit, let out an aaaah, like you do when you get home in your comfy chair.

1/4 scale, I believe.

Rev knows everything about planes as he's read the entire internet.
He disagreed with 92% of it, but still...

Just remember when you’re putting your faith in what a pilot says, most planes crash because the pilots fuck it up

I’ve done some research, there’s a worrying trend I’ve identified when analysing the lead up to these disasters. Rev wasn’t consulted by the aircraft manufacturer, the airline or the pilots on EVERY SINGLE FLIGHT THAT HAS CRASHED IN THE HISTORY OF FLIGHT!
