The Sycamore had something between the engine & rotor which it wasn't given for pilots to know about,but required similar stature.On 1563 Flight Nicosia during autumn 1963 we had on strength a fitter who answered to "Gnome." One night the troops came and woke me; Please Sir,can you come in and disconnect the (whatever) -- Gnome's off sick and no one else can get in. So off I went,crawled into the tubular frame that supports the MRG and disconnected either the rotor shaft or the centrifugal clutch. "Thanks Sir,we'll run you back." Thus demonstrating that not all officers,while decorative are fairly useless!
