The PDF says that the fuel switches both were switched off with a 1s gap between them. Ten seconds went by before the Engine 1 switch was turned back on, and another four seconds passed before the Engine 2 switch was moved to the on position. During the ten seconds the fuel was cut, the CVR recorded one of the pilots asking the other why he cut the fuel, and the response was a denial.
I agree that the timing of the switches coming back on is a possible indication of the switches having actually been moved. I also find it hard to believe that the pilots were not speaking a lot more during this event. Where is the cussing. Where is the “Oh my God” “We are all dead” “I am turning them back on” ect.... They are hiding something.
