Thanks for the links folks - an enjoyable puzzle with a popular theme. In fact all four pairings can be found in Brewers, 17th Edition, available on-line via Credo reference.
Enjoyable, I agree, and I have completed it using the Internet, but couldn't find a single one in Brewer. I do have the seventeenth edition but, with the lack of a real index, don't know where to look for this one!
Thanks Kayakamina.
Congratulations to MNL and Mr. McBain if he is also an Abacker and may be reading this.
Two weeks in a row now that ABackers have won. Slaney being the winner last week.
I do think that I had rather an edge with this one having spent many years in the airline industry.
Thanks to all for your good wishes.

There are plenty of online sources for the unclued lights - essential as I don't have Brewer. I felt that Doc's clueing was almost too straightforward this week - a very quick solve!
