Loved that Jezz... In the days when there were TWO ATCOs in the tower at night, we were messing with the lights writing "XOX" on the inner and outer taxiways. Brian Buckingham (RIP) was the lighting op and he pressed a switch and reduced the airfield to total blackness to frighten us to death. Seconds later approach warned in a Vanguard at 10 miles and Brian couldn't get the lights on again. Some fairly frantic phone calls and hands flashing around like lightning restored the lights as the Guardsvan passed the marker!! Happy days...
