A C130 disgorges a Huey at Alice Springs, in the middle of the GAFA (Great Australian F-All) and flies away. Huey gets put together, crew hops in for an Army exercise. Copilot realises he left the nav bag on the Herc. No maps.
Not to worry, trot down to BP garage, buy a road map. Launch off for exercise, realise that there are no roads in the area of operations. But keep on going, it will come good soon.
Army Major in back seat asks cojo to pass the map back to him for a look. Forgets that the doors are pinned back. Pfffft!and map zips out the door. Oops...
