We have zero knowledge about what happened in this case.
I was under the impression that the aircraft was flying towards a known band of weather, had asked for a level change and shortly after this contact was lost.
In my first post and for the benefit of non pilots I was simply outlining the piloting actions I was taught (many moons ago) in the event of encountering extreme turbulence or loss of airspeed indication.
If you see that as me banging a drum of hate I can only apologise for confusing you.
