By 15 November 1941 the flight moved to RAF Predannack, Cornwall.

[3] During its operational life the flight had three sightings of possible enemy aircraft.

The first occasion was on 24 June 1942,[4] when the flight lit up a suspected Ju 88 and the satellite fighters of 247 sqn fired - on a RAF Short Stirling.

[4] Others sightings occurred on 27 June and in August, but no enemy aircraft was shot down.

[3] 536 Sqn, which had taken over men and machines, carried on flying the Turbinlite Bostons and Havocs till the system was abandoned on 25 January 1943,[6] when Turbinlite squadrons were, due to lack of success on their part and the rapid development of AI radar, thought to be superfluous.
