Have you considered the Rapture angle?
There are angles that many people are considering... they go beyond my little mind. Religious... yeah, that does match up.
Same with aliens... I mean, hundreds of former world & military leaders say we've been visited, and they're a part of things here. It's pretty silly these days to say we're alone. And yeah, if they can travel that far with that technology, if they they can pull people for any reason, then they can make a plane disappear, sure.
Or the terr'ist angle... took the plane, landed someplace and they're having a standoff right now, without the cameras.
Or, the govt bad guy angle... someone controlled the plane and make it land somewhere and took people off the plane.
Who the heck knows. most likely a crash, but wow.... any one of those pings or signals can disprove that... I'm stumped on this one. The biggest fools are the ones that say they KNOW what happened here. We jsut dont...
