I have flown with some of the ex RAAF Herc drivers from those days and didn't realise that the Herc was responsible for flying all the components of the Bailey Bridges into the highlands from Lae and Madang. Those guys were having as much fun as us GA buggers.
Flying low in the Highlands these days could be hazardous to ones health as the likelihood of being hit by small arms ground fire is now more dangerous than the terra firma. Numerous stories of guys being pot shot at.. mainly from home made guns. Surely taking the meaning of customer complaints to a whole new level!
