Good post, Jacko and excellent research. Thanks.
Wasn't the Lightning on Harrier event because the Harrier pilot had ejected, the impetus of which redirected the flightpath of the jet towards East Germany (the engine having spooled up again) and therefore the decision was taken to shoot it down before it ended up in enemy hands!
At least so the story went around the bar at Happy Hour at LLK in the 70s!
