BOAC B707 ops in the 1960s

[Discorde]

I might have to divert my 707 into Sondestromfjord. Latterly the approach into BGSF was LOC/DME. Was that the case in the late 1960s? Was there SRA or PAR available? Did crews use weather radar to assist with nav (terrain) orientation?

Thanks for info.

Edit: The field was under USAF control in the 1960s, so the approach aids would presumably have catered for military aircraft.
