Flight 370 did not disappear

“I believe,” he writes, “that what most likely happened to MH370 is that pilot Zaharie Ahmad Shah detected an electrical outage followed immediately by severe smoke in the cockpit less than one minute after signing off with Kuala Lumpur air traffic control.”
 
He suggests that the fire originated on the left side of the electronics bay where the communications systems are housed, including the circuits involving the transponder and ACARS. A fire confined to that location would leave untouched the autopilot systems that were 15 feet away. Overcome by the severe smoke in the cockpit the pilots were unable to report their plight over the radio, Soucie argues, because a tight seal muffled the microphones in their oxygen masks. (A fire in the electronics bay would not have affected the radio.)
 
Soucie points out that the sudden turn left away from the flight path to Beijing is consistent with the pilots attempting to head for the nearest airports at Langkawi or Penang. Indeed, another expert I spoke to said “the crew may still be proven to have been making heroic efforts to try to save the jet before they passed out.”
 
Soucie is so concerned about hypoxia that he proposes that airliners should be fitted with a device to detect loss of oxygen before it becomes fatal, and sets off an alarm – an airborne equivalent of the canary in the coalmine.
