PBY Nav technique
To: I M Esperto
IME , you mentioned you had pal who flew Cats in WWII.
I'd be interested to hear what nav techniques were used
on the long range patrols over the Pacific.
I guess the B3 Gyro Stabilised Drift Sight & Bubble Sextant must have been key equipment. The need for radio silence probably would preclude the use of HF/DF & VHF/DF in most areas in the early days of the conflict?
