The Typhoon did not begin to mature as a reliable aircraft until the end of 1942, when its excellent qualities — seen from the start by S/L Roland Beamont of 609 Squadron — became apparent. Beamont had worked as a Hawker production test pilot while resting from operations, and had stayed with Seth-Smith, having his first flight in the aircraft at that time. During late 1942 and early 1943, the Typhoon squadrons were based on airfields near the south and south-east coasts of England and, alongside two Spitfire XII squadrons, countered the "Luftwaffe"s "tip and run" low-level nuisance raids, shooting down a score or more bomb-carrying Fw 190s. Typhoon squadrons kept at least one pair of aircraft on standing patrols over the south coast, with another pair kept at "readiness" (ready to take off within two minutes) throughout daylight hours. These sections of Typhoons flew at or lower, with enough height to spot and then intercept the incoming enemy fighter-bombers. The Typhoon finally proved itself in this role; for example, while flying patrols against these low-level raids, 486(NZ) Squadron claimed 20 fighter-bombers, plus three bombers shot down, between mid-October 1942 and mid-July 1943.
