In truth, a lot can now be known with certainty about the fate of MH370. First, the disappearance was an intentional act. It is inconceivable that the known flight path, accompanied by radio and electronic silence, was caused by any combination of system failure and human error. Computer glitch, control-system collapse, squall lines, ice, lightning strike, bird strike, meteorite, volcanic ash, mechanical failure, sensor failure, instrument failure, radio failure, electrical failure, fire, smoke, explosive decompression, cargo explosion, pilot confusion, medical emergency, bomb, war, or act of God—none of these can explain the flight path.
Second, despite theories to the contrary, control of the plane was not seized remotely from within the electrical-equipment bay, a space under the forward galley. Pages could be spent explaining why. Control was seized from within the cockpit. This happened in the 20-minute period from 1:01 a.m., when the airplane leveled at 35,000 feet, to 1:21 a.m., when it disappeared from secondary radar. During that same period, the airplane’s automatic condition-reporting system transmitted its regular 30-minute update via satellite to the airline’s maintenance department. It reported fuel level, altitude, speed, and geographic position, and indicated no anomalies. Its transmission meant that the airplane’s satellite-communication system was functioning at that moment.
By the time the airplane dropped from the view of secondary—transponder-enhanced—radar, it is likely, given the implausibility of two pilots acting in concert, that one of them was incapacitated or dead, or had been locked out of the cockpit. Primary-radar records—both military and civilian—later indicated that whoever was flying MH370 must have switched off the autopilot, because the turn the airplane then made to the southwest was so tight that it had to have been flown by hand. Circumstances suggest that whoever was at the controls deliberately depressurized the airplane. At about the same time, much if not all of the electrical system was deliberately shut down. The reasons for that shutdown are not known. But one of its effects was to temporarily sever the satellite link.
An electrical engineer in Boulder, Colorado, named Mike Exner, who is a prominent member of the Independent Group, has studied the radar data extensively. He believes that during the turn, the airplane climbed up to 40,000 feet, which was close to its limit. During the maneuver the passengers would have experienced some g‑forces—that feeling of being suddenly pressed back into the seat. Exner believes the reason for the climb was to accelerate the effects of depressurizing the airplane, causing the rapid incapacitation and death of everyone in the cabin.
