Capt Wally, spare pads of flight plan sheets. And the best thing of all, when I was working as the relieving office girl/aeroplane washer/drinker of free XXXX proferred to underaged drinkers at RFS, Clients would ring up to see where an aeroplane was. A quick call to briefing over at AF would give me a last position and ETA for the field. Try doing that now!
