As an ATCO we had very specific instructions about how to deal with a Concord(e) radiation overdose. We were told that it would have to make an emergency descent and how to integrate it with other traffic as it descended and what the priorities were.
Has any Concord crew ever had to do this?
I dealt extensively with the London sector (S23) most likely to be involved in this procedure but fortunately it never happened to me.
