Clive Horton was a Heathrow air traffic controller whose routine day’s work turned into a nightmare when Concorde flight 192 disappeared from his screen. He kept his cool and reported what he saw to his superiors. Later he noted the same thing happening to the second Concorde, and saw it return a few minutes later when The Doctor brought it back from the Jurassic era.
