It's good to talk - PLEASE !!!
As the first anniversary approaches, people and organisations are understandably getting nervous.
At least twice this morning aircraft have been out of touch with French ATC for extended periods - one from Bordeaux to BARLU, the other for a lesser distance. Both have then found a French Air Force Mirage keeping them company. It may create some amazing photo opportunities, and give the military some useful practice, but it is not a very professional example of airmanship!
Both crews arrived on London frequencies a little chastened by their experience, but it could have been so much worse.
My worst fear is of an unrelated emergency occuring, such as a de-pressurisation, which requires a rapid descent. If the airliner happens to be in the vicinity of a "sensitive" location, normal emergency procedures may appear to have a totally different interpretation when viewed from the cockpit of an armed intercepter. The military pilot may have just seconds to decide on a course of action that could have consequences too frightening to contemplate.....
