The Malaysian government officially declared on Jan 29, 2015, the disappearance of the plane an accident, which in another way pronounced the 239 people onboard dead, shattering the hopes of families and friends that their beloved ones may still be alive.
Speculations about what happened to MH370 range from sober, science-based arguments that the plane has crashed into the southern Indian Ocean, but not necessarily in the current search area, to the wild - alien abduction, MH370 and its doomed fleetmate MH17 were the same plane.
None of the speculations will convince the public until the truth comes out.
