My tipping is a human-induced event or bought down by rogue missile.

If it were a rogue missile, it would have to have been a large surface to air missile from a fixed or mobile launcher. MANPADS cannot get up to that altitude.

An onboard bomb is more likely than a missile.

To be fair, if one is going to speculate about missiles, gotta consider those taken up to the altitude of the airliner - a shoot-down.
