Thanks chaps. Yet more questions:
Which F/D did the BOAC 707s have: Collins, Smiths (or none)
How was A/P hdg adjusted: bug on capt's HSI or remotely?
How noisy was the cockpit? Was 'headsets off' feasible for oceanic/HF/SELCAL ops?
Were there two Loran sets for redundancy?
Thanks (again) for info.
