A Large Portion, Yes
Unsure what you mean. All we were doing in both quoted texts we were just stating possibilities, not assertions. Assuming it was air defence aimed at the aircraft, then yes it didn't miss. But it could have. An explosive device on the plane almost can't miss (but of course there are other risks there such as early discovery).It has never been determined it actually was the wrong target. And they didn't miss.
Another thing I read was that there were two explosions, which is also notable, but I hadn't looked any further into that.
