At this point it seems the best probability of finding the B-777 is with acoustic sensors lookng for the flight data recorder (it pings).

If they don't dind it then maybe a UFO plucked it out of the sky and transported it to the future to repopulate the world after... sorry, too much SciFi.

Really strange that in this day and age they have such poor tracking on a commercial aircraft.

...or, whomever was in control of the aircraft deliberately made it lost.
