You will have to be more specific than "one of my bombers".
If I recall correctly, if your lead bomber (the one you are in control of) gets shot up and loses a wing or a tail, as you fall, the drones will flip and follow you down. You have to bail from the plane you are controlling which will put you in the next plane in line. After that, your plane and the other drone will regain flight control and course.
If it was one of the drones that was shot to pieces and you still had that problem, then yes, you may have found a new glitch.
