In B's frame the right hit happened first and the left happened later. There is no way to objectively decide that one's interpretation of the events are correct and the other's incorrect. Separated events which are simultaneous in one frame are not necessarily simultaneous in another. Meteor hits left end. Meteor hits right end.
B sees right hit.
A sees both hits simultaneously. B sees left hit. There is no question between the pilots that these events happened. The only question is the interpretation of them. It is this interpretation that is relative.
