"An aircraft which was believed but not confirmed to be MH370 did indeed turn back," Razak told reporters. "It then flew in a westerly direction back over Peninsular Malaysia before turning northwest. Up until the point at which it left military primary radar coverage, these movements are consistent with deliberate action by someone on the plane."
As a number of commercial pilots told NPR's "All Things Considered" on Friday, with the exception of the transponder, which can be shut off at the flick of a switch, other onboard tracking systems are not as easy to disable.
"They said you'd have to go through big checklists, you'd have to possibly pull circuit breakers if you wanted to deactivate [all the communications equipment]," NPR's Geoff Brumfiel said, citing interviews with pilots. "So, to do this, you'd have to have some degree of premeditation and a lot of knowledge of the aircraft."
