Bolid

If you mean "Bolide" then it had to have come through the Earth... triangulation of the eye witnesses show that it could not have come from beyond the horizon relative to any witness.

Sure it did ~ just didn't start glowing all that much until it was right near the plane, which it then smacked, and then flew on away from the Earth. (To understand this you must think of the Earth as "round" and not "flat")

The eyewitnesses would perceive it as an object rising up from the Earth to hit something.

Ever been in an airplane struck by lightning? Happens with some frequency BTW. Every now and then lightning will take a plane out of operation.

Here we have a rock flying in from space and taking out a plane. Won't happen all that often, but it can't be ruled out.
