After being told to turn off mobiles, laptops and all other electrical equipment due to interference with the aircraft controls. Could this be a ground based outside influence?
An "electronic storm" or whatever the geeks call it?
If there is fuel still on the aircraft, as reported by the beeb yesterday (although with one main gear ripped off and the other stuffed through the trailing edge I cant believe there wouldnt be a leak with potential fire risk??)
I cant think of anything failure-wise that would end up with a total loss of power.
