Once total boredom set-in, many a Lightning guy would start to dismantle bits of the cockpit or, more usefully, go around and tighten up all the loose securing devices, attempt to bring dead P-Lamps back to life etc.
There were several tales of people being embarrassed with bits of the aircraft all over the place when out of the blue the Telebrief requested them to get airborne
Of course, faced with such little problems, both engines always started first time so off one had to go and sort things out somewhere around FL360. For non-Lightning readers, it often required witchcraft to get the Lightning AVPIN engine starting system to fire up.
