93 Sqn Linebook No. 2 - Page 34 Continuing on the saga of Johnny Johnston's flame out.   The entries in the Form 700 Aircraft Servicing Record state that: "Engine ground run to full power and found serviceable.   Relight switch checked for function.   Fully serviceable.   Aircraft serviceable for test flight.   Test flown - serviceable."   Other comments are: "So that's what they mean by S.O.P."   "Lets face it Johnny you should stick to brandy in future, if I hadn't tilted your wing you'd never have made it."   Sure I had the H.P. cock wide open just like this."   (Thanks to RAF Museum.)
