Reely,
Beating your head on the wall.....really?
Why would the same exact pairs of switches be in the same position even though right next to one another in the over head panel.
What is more interesting is the configuration noted by the AAIB is exactly opposite of the switch position one would assume would be the case for normal operations.
This switch position thing is one of many issues that needs explaining if we are to make sense of what happened that night. Sadly, there is not going to be anyway to know definitively how they came to be in the positions they were found.
They could have been moved there by the Pilot, moved there by the Impact, or a combination of both....how does one determine the truth of the matter?
