We can't see the wood for the trees.
We've got so immersed in MCAS that we're missing the point. Its not MCAS,its the UAS.

I cannot concur here.
The Boeing software design error is proven and accepted. Thats not the point here though.This crew did not fly the plane. Single side UAS after takeoff is not...

Yes you are of course correct but that doesnt alter the fact that crews who

The Flight Radar data fits another MCAS event and not much else.
737s dont just augur in.
Flap retraction can be initiated as low as 400 feet,more commonly 800...
