I remember Idris - or Castel Benito as some people still called it - as having the classic semi-recessed lighting of the period. White on the runway, with the peri-track lit by amber on the outside, blue on the inner. This was in June and August 1956, to and from Accra in an Argonaut.
The terminal building was another classic of the period, think 'Casablanca.' Cane chairs, slow swirling fans in the ceiling, and waiters with fez hats. On production of your plastic B.O.A.C. transit boarding card, you could get a soft drink and stand on the terrace outside, watching the aircraft being overwing refuelled, and the new crew walking out to it.
I do have a recollection of landing and taking-off on a gooseneck lit runway - at East Fortune in June 1961 - during the temporary move from Turnhouse for runway resurfacing.
