It is quite staggering that we still have not been told exactly why both Max 8 planes flew into the sea/ground.
Boeing MUST know now exactly what caused both flights to crash. In fact if they do not know it is even more worrying.
What are they covering up?
Something else is wrong (something sinister) with the plane for certain.
apart from the fact it is out of aerodynamic balance of course.
Well worth a read https://spectrum.ieee.org/aerospace/...ware-developer
Excellent article, pulls no punches. Was free open access but now they make you register to read it.
Registered and read it.Quote:

I often wondered why the 737 air intakes were oval. Looked cool but now I know the reason.

MCAS a cheap way to prevent a stall when the pilots punch it.
WOW !
The elevator feel computer.
This basically exhausted the poor pilots.
WOW!
The Max line of 737s are flawed and not airworthy controlled by safety software that makes them crash. Boeing intend to leave them unairworthy and rewrite the software.
As a former computer programmer I think the MCAS computer put the planes controls in a subroutine that made the plane crash. A subroutine from which the pilots could not escape.
Tragic and a ****ing scandal that must be exposed. This might be the end of Boeing let alone the Max 8.
The plane is shite.
Boeing have now returned to "pilot error" line of defence. A plane that doesn't fly as well as it's predecessors, corrected by software that makes it difficult to fly. No wonder passengers are keeping away from the Max 8.Quote:

The planes crashed themselves EVEN AFTER the autopilot was disconnected.
Where are the official explanations for these DISASTERS. With the worlwide fleet grounded the operators should be told immediately. What are the USA and Boeing hiding.
There was an article in The Times a while back that explained the issue. From memory, the engines are further forward on the Max 8 to reduce fuel use when cruising. But, as the engines are further forward more lift on take off is needed with a subsequent need for a steeper (?) angle of take off. But, dodgy software forces the nose down as it is thinking the plane is going to stall. Not good. Boeing issued "what to do" guidance to pilots, if this occurs. It did happen again and the pilots couldn't regain control despite following the amended procedures. I think that was the gist of it and maybe is already covered in the article linked too, above. So....design issue, combined with software issue.....and maybe rushed to market in competition with Airbus (A350?). And when it all goes wrong, to protect the brand image and jobs, blame the pilots.Quote:

Hence some pilots have described flying the Max 8 like being on a bucking bronco, struggling to control it. The old system of warning pilots of a potential stall worked. This plane just appears to be too complicated with conflicting data inputs.Quote:

The 737 was one of the best designed planes ever and was adapted many tines to fit more seats. Safely.
Boeing pushed the envelope too far with the Max8.
The plane with these engines where they are is garbage.
It’s like putting a 5 litre engine in a Lotus Elise and expecting it to handle safely. Ridiculous.
But there is something else involved that we have not been told yet.
It will be terrifying.
Like the tragic flights.
this aircraft is doomed isn’t it? At some point the fault will be fixed but surely it’s reputation has been so tarnished so publicly that airlines will fear ordering them? A lot of people already know which aircraft/airline combos should be missed (economy BA on a 787 for example) and enough people already have an irrational fear of flying that they would avoid the 737 Max?
