What?? Why on Earth would the pilots turn the computers off??
...
Look at the story of AF447. The computers on an airbus can cause confusion for marginal pilots when there are problems with the sensors.

Likely cause here is these guys were in turbulence/t-storm they never should have flown into and were trying everything, when jsut skirting the weather by 60-70 miles would’e been the right decision. Planes aren’t designed to fly through storms like the one they encountered and they should’ve changed their route.
