Noon Fixes
Ahh (sigh) Noon fixes, SOP for daylight Gan-Singapore. Sextant melts in mounting. Never had the pleasure of comparing with GPS, so had to have blind faith that the system worked. Seem also to remember doing a noon fix using the sun for latitude and working out the longitude from the time difference between LMT and GMT. Only did stupid things like this when there was nothing else going on.
