On the other hand, this is a good story. From RISKS DIGEST, Volume 19: Issue 75, May 1998
30+ years ago (1968?), the brother of a Navy navigator friend (also a Navy nav) was assigned to VX-6, the Navy C-130 squadron that provided logistics support out of Christchurch, NZ, for the annual wintering-over expeditions to the Antarctic. On one trip, after departing the ice shelf in a near white-out for a return trip to Christchurch, and climbing out to VMC [Visual Meteorological Conditions] on top of an apparently endless cloud deck, the aircraft suffered a TOTAL and complete electrical failure. No AC no DC (after batteries depleted), no comm, no nav, no nothing; VMC on top with all directions NORTH. Well, using just his periscopic sextant, HO-214 (the Air Almanac), and a chart, he was able to continuously shoot the sun to get a True Bearing to the sun, work backwards, and compute headings to fly to Christchurch... The aircraft arrived successfully, and he was awarded a Navy Commendation, etc. All done with a sextant and chart. Nice work.
There is also a good poke fun at the AF story here:
