Passing between the Shetlands and the Faroe Islands a soviet Tupolev Tu-142 long-range surveillance aircraft is intercepted by two FG1 Phantoms out of Leuchars, Scotland. The Phantoms escort the Bear away from the UK air defence regions, which cover around 4 million square miles. All incoming aircraft that have not filed a flight plan must be investigated. QRA (Quick Reaction Alert) aircrew are ready day or night, in all weather conditions, and always find their target. This scene would have been a regular sight for QRA Phantom aircrew investigating Soviet aircraft.
