That was a 737-800 (newest model) that crashed yesterday
I believe you are mistaken The new 737 max which is the newest model are all grounded and have been for some months.
Hi John,
The 737-800 & 737max are two different aircraft, I know the 737max has been grounded since last year. There is an updated 737-800, it’s the one with the thinner seats & bigger luggage holders. I thought I heard that the crash yesterday was one of those but may be wrong
My apologies you are correct Ron the 800 is a tweaked version of 1990,s design while the Max is a new design.

I read an interesting article on The Max a month or so ago, apparently, the 737 was originally designed with a shorter undercarriage than other jets supposedly to make passenger access easier, but modern jet engines are more economical but fatter than the older ones would not fit under the wings of a normal 737, so the solution was to move the engines closer to the fuselage the, unfortunately, this made the aircraft less aerodynamic and gave it a tendency to go nose up, the solution to this one was to fit something that counteracted this, and made The Max react like any other 737, which removed the need to have pilots retrain on them, now I am no techie and I am going from memory, I believe that as standard, there was no cockpit indicator that told the pilot that this had activated itself, they were allegedly available but at more cost so were not fitted and these it is being speculated is what caused the nose down attitude of the crashed aircraft, as a layman I would have thought if it was a simple as that, either removing the device and retraing pilots or simply fitting a warning device as standard would have resolved the issue.

Also the repositioning of the engines could in certain conditions (ie full throttle on takeoff) but not always, cause the nose of the aircraft to raise and induce a stall. Being at a relatively low altitude and full power going to the engines this is a very dangerous situation to be in as recovery is almost impossible.

I guess they could use Lauda crews and planes but is there enough spare capacity there? Even if there was it still leaves them with extra 737 pilots.

I don’t think it’s simply a case of removing or adding a switch/light. From what I heard you are pretty much right John but the “compensation” system to counteract the nose lift is an integral part of the whole aircraft system software so maybe not an easy fix. Hopefully resolved sooner than later & it can show a few months of reliable use. Once it’s shown to be safe in daily use people will feel more comfortable booking tickets. I certainly wouldn’t be keen until time has gone by
