Oh, dear
Sriwijaya Air Boeing 737 passenger plane missing in Indonesia https://www.bbc.co.uk/news/world-asia-55601909

The article states it was NOT a Max 737 ;)
Still very bad though :'( :'(

I never mentioned Max ::)
;D ;D ;D

Was it a Max?

Was it a Max?
You are joking ???

I don't think they named the "plane driver" yet ;D

An incident involving of one of the most prolific aircraft ever made is a bit like saying a white Ford Fiesta was spotted in a Tescos car park.
If something significant happens to a flight the chances are that it involves either a 737 or an A320ish aircraft.
Pilot suicide, botched hijacking or a bomb.
That part of the world is probably best avoided if you're afraid of flying... Unpredictable weather/politics/religion and sub par training and regulation all conspire to make flying around Indonesia about as safe as walking through Streatham at 2am.
That BBC article is stuffed with a whole lot of nonsense about the 737 Max which, whilst it mentions that it wasn't the specific type that crashed, implies that it's somehow relevant. Which it isn't. They're just using it as an excuse to mention it because they're back in service.
Regardless of Boeings' numerous shortcomings, the LionAir flight crashed because the Captain was taking flu meds and the F/O wasn't experienced enough to deal with what was happening. The Ethiopian one probably wouldn't have crashed had the crew understood why the aircraft was behaving as it was, especially in light of the first crash.

I think that was the primary problem in reality, the Max wasn't inherently unsafe, but a lack of extra training for flight crews on the new systems implemented due to the new engines. Boeing could have made the systems more resilient*, but crews should still be trained fully on all failure scenarios. So the airlines are every bit to blame.
*and I think Boeing went out of their way to make out it was a minor upgrade, and implemented it very badly, and blah blah, so shouldn't be absconded of blame.

Well, they've found the aircraft and the black boxes, so shouldn't be too long before the cause is revealed.
Hopefully they'll also find bodies in order to return them to their families.

The selling point of the MAX was that no crew retraining was required to fly it, so Boeing actually went out of their way to hide differences in the systems from the crew.
That didn't end very well for them, as it turned out.

(6 min) Usual annoying music but otherwise a worthwhile look at the 737 Max issue from 2019

I always think MAX has a unfair reputation , I thought he was great in Hart to Hart :y
-
It is pretty much a 73X NG fuselage with bigger engines...
But there's probably more than one engineer at Boeing wishing they'd gone with the 757 as the base programme instead of the 737 ::)

Well, the preliminary report is out...
First issue was that both pilots failed to notice an auto throttle disparity, and once the autopilot could no longer compensate, the thrust discrepancy rolled the aircraft left and down...
Think the back end of your Omega catching some ice on the centre line as you boot around a left hander on a fast, wintry B road.
Basically, they weren't expecting it and failed to recover from it.
The aircraft had recent defect history regarding the auto throttles, but each time an issue was found, it was rectified and tested as being serviceable. And in any case auto throttles aren't part of the minimum equipment list, so had no bearing on the flight.
Had the crew read back through the defect log they would have been aware of the possibility of issues with it and could either have trimmed the aircraft to compensate for the asymmetric thrust or manually operated the throttles.
Either they didn't read it or they failed to allow for this possibility, and in any case they simply didn't notice that the left engine had throttled back slightly. (engine thrust being a dominant part of the engine displays).

Ain't going on no aeroplane Hannibal..

for the asymmetric thrust
I vaguely recall following that little hiccup on a 737 in Manchester way back when that significant asymmetric thrust was a cause for concern, and something that should have alerted the pilot to the fact that a load of people were gonna die on the runway... ?
-
Apparently that was an uncontained compressor failure caused by a botched previous repair. Secondary was opening the wrong door, turning the cabin into a blast furnace... The cabin being full of rathermorecombustiblethanisgenerallyacceptable material notwithstanding :-\
