Radar shows that near the plane at the time of its disappearance was a "UFO." That can be seen here:
This has also been reported sparsely in other places.
The information that has been given has said that in under a minute, the plane ascended to 45k ft, disappeared from radar and then through classified tracking, it was found to have descended to 23k feet (in less than a minute) - an act that would most assuredly kill everyone on the plane and tear off the wings while doing so. However, according to the information given, that didn't happen and the plane continued flying for up to seven hours at 30k feet.
Doesn't make sense and seems nearly impossible that a plane so large could do such maneuvering without breaking up or sending signals to ground control.
Could the "UFO" have been a military jet, which is actually capable of descending from 45k ft. to 23k ft in less than a minute and then re-stabilizing?
After disabling the plane's communication systems, the cloaked plane was remotely flown to another location. And the tracked pings were actually the military jet? It was initially reported that the "UFO" had always been tracked but was ignored because it didn't communicate as the 777. Maybe because it wasn't. They now believe that it was.
This would also explain why the plane could be in one of two places: The plane could have flown to the south in the Indian Ocean or to the north, maybe even as far as Kazakstan. Did the plane fly south and the jet fly north?
Remember, even though the transponder is off, when the plane hits the water, it would automatically begin pinging. That has never happened, which suggests that the plane never touched the water or even crashed for that matter.
Just a theory.
