Regarding diversion - its an interesting question ... I know BA's two flights to YYZ ended up in YOW & YUL, but I don't know if that was pre- or post-incident.
Regarding BBC ... reporting was ok, diagram was poor, "have your say" was shocking and they shouldn't have put that page up ... some utter BS on there!
As I said earlier, maybe all this pontificating isn't the best idea?
