New theories arise in search for Flight 370

Without the black box or any piece of wreckage, investigators cannot rule out Flight 370 went down in the Indian Ocean because of an accident.
“It sounds to me like there was an incapacitation in the aircraft and they possibly just flew it out on autopilot until it ran out of fuel and down it came,” said former NTSB board member Steven Chealander.
According to this theory, the plane reaches altitude, and some time after the famous “alright, goodnight” transmission, what's called a catastrophic decompression of the plane takes place. No clue what might have caused that, but some have theorized, it could be as simple as a partially-opened door on the plane, or sudden smoke, or fire, causing the pilots to alter their course and seek safe harbor immediately. No mayday call took place because there was no time.
“In the first few minutes, the pilots had to change course for an emergency airport. They were overtaken by whatever it was – smoke, fire. The plane was left to fly itself after being reprogrammed.”
The crew would likely have had only seconds to react before losing consciousness. Changes in altitude would have occurred.
“As far as we can go on the radar, the plane could have oscillated and zig-zagged. If it lost altitude, that would have been consistent with losing cabin pressure. The first thing a pilot would do with a decompression problem is to lose altitude so that the oxygen could return to the cabin.”
The crew and passengers would have passed out as the plane continued on until it ran out of fuel over the Indian Ocean. Something like this has happened before: a chartered jet carrying golf star Payne Stewart lost cabin pressure while cruising on auto-pilot. The people on board suffered hypoxia, or an incapacitation due to a lack of oxygen, but the plane continued flying almost four hours before crashing in South Dakota. Whether the answer is ever known in this case depends on what debris gets recovered, if and when, the plane is found. Meantime, experts say the dials and gages, conditions of passenger remains, even the engine could, and would, hold clues to the condition of the aircraft.
