The disappearance of Malaysia Airlines Flight 370 has been the tragically ultimate crowdsourcing for an answer. The journalists at the Wall Street Journal and The New York Times, among others, have distinguished themselves with exhaustive reporting, dozens of nations are in search mode and likely hundreds of millions of people have their theories on what may have materialized on that flight ten days ago. The one thing that does seem certain now is that this was not an accident.
The last transmission was from the co-pilot, Fariq Abdul Hamid, though still in question is if his “All right. Good night.” came before or after other communication systems were shut down. What is known is that the 777 then turned off its flight path northeast toward Beijing and headed west at approximately the same time time it was flying at 45,000 feet, which is roughly 2,000 feet beyond its certified maximum altitude. Consciousness at this altitude without additional oxygen would last no more than fifteen seconds. The jet then descended to 23,000 feet before ascending to just 30,000 feet.
A possible conclusion is that the communications systems were disabled oy one or more of the flight crew, flew the aircraft to 45,000 feet thus killing all on-board except for those equipped with supplemental oxygen, descended to an appropriate altitude with the intent to fly to…….where? And did they make it there?
This story explains why there seems to have been no communication from any of the passengers via cellphone. http://www.nytimes.com/2014/03/18/world/asia/questions-over-absence-of-cellphone-calls-from-missing-passengers.html?hp
