Having spent some time at Boscombe Down (and about to return as a 'civvy' for the second time), the Hunter TPs loved breaking into the circuit at the 'Blue-Note' speed (was it the F6?). I still live within two miles of Boscombe and I cannot help but notice a 'new sound on the block'... the Tornado now regularly breaks into the circuit with an equally haunting note! I'm not complaining... I just wondered how it was discovered? New/modified gun pack perhaps? I don't know... but it sounds... YEAH!
