Murphy's Law.....
Had an alternator fail at night in a C172. 90 min flight down the QLD coast.
Nice clear moonlit night. No where to land. (No PAL then!)
Continued on with 30min skeds, with the master switch off in between to save the battery for arrival. No drama really.
Another at night, in western QLD, the compass in the Baron went tits up.
Came home using the moon as a reference until within navaid range!
(Compass bearing of moon provided by Flight Service... aahh the good old days!)
