Very interesting post. Just remember the younger ATCO's do have emotions. I am sure I heard in the last Concorde flight from LHR the young ATCO going something like:
"Concorde (blub blub) Line up runway (boo hoo tears) 27 (very tired and emotional moment) Left ...."
He was young and obviously either was doing it for media effect or showed feelings. Yes a young ATCO with feelings ;-)
