For my money, more interesting than the Amelia Earhart story.
Just read a new update/review of some of the past/present theories.
MH370: five years of theories about one of aviation's greatest mysteries

Didn't click that article, but I have read a lot about MH370.
No mystery at all for me. The evidence is overwhelming that it the aircraft was deliberately flown to and ditched in the southern Indian ocean.
-Turning off transponder, and deviating from planned course in between controller hand-offs.
-Hugging the Maylasia/Thailand border, in a commercial radar deadzone.
-Inmarsat ACARS pings tracing a route to the most remote place on earth.
-The lack of a large floating debris field, and the erosion to the recovered flaperon both suggest a controlled ditching.
There is also pretty strong circumstantial evidence that points to the captain as the culprit.
-The same route MH370 took saved on his home simulator.
-MH370 made a detour/turn to fly over the Captains hometown.
It's no mystery to me what happened; Captain waits till controller hand-off so he has some time before anyone notices the situation, somehow locks out or incapacitates F.O.(could have happened before hand-off) Turns off the transponder, goes NORDO, flies past his hometown for one last look. Then cruises out to the middle of nowhere for 7 hours till fuel runs out and ditches in the ocean. Whether he depressurized the cabin to kill all the passengers before ditching or not... who knows, but probably.
MH370 is sitting on the bottom of the Indian Ocean somewhere mostly intact.
