The Indian government should inspect all phone calls, social media and text messages of the pilots and identify any suicidal or terrorism ideation.
ONE switch moving accidentally is 1 in a million. BOTH switches within 1 second of each other? Intentional.
The switches cannot move on there own, the switches were not bumped simultaneously but were intentionally placed in the cutoff position one after the other(with one second in between actuation). And the only reason a pilot would say “Why did you cutoff?” would be if the switches were in the cutoff position. If an engine fails you say “engine failure” and not “Why did you cutoff?”
