BOAC B707 ops in the 1960s
I am researching background for a novel set in the mid-1960s. One of the (probable) characters will be a BOAC B707 captain. Some questions:
Did BOAC employ dedicated navigators in the mid-1960s or were nav duties carried out by pilots with Flight Navigator Licences?
Was LORAN the primary nav aid with astro as back-up, or the opposite? Did the B707 feature a periscopic sextant for star shots? If so, how did it operate?
On the North Atlantic was the current NAT system in use, with available tracks varying daily? Was longitudinal separation by Mach No the standard procedure? How many miles was lateral separation?
Did crews routinely contact the fixed-location weather ships for position reporting or weather info or use them for nav guidance (ADF bearings)?
Were supernumerary or cruise pilots usually included in the flight crew?
Did operation into JFK differ much from current procedures?
Where was BOAC's Crew Report location?
Thanks for info.
