I've tried to find some historical information on Brisbane Eagle Farm prior to the 1988 expansion, with little luck.
I have vague memories of a visit there aged 5 in 1984, with an international terminal that was like an enlarged shed; and contrast that to the impressive and spacious version on the other side of the runway that is there today.
Older maps of Brisbane seem to show smaller runways to the bottom of the present airport - was that the extent of Eagle Farm?
How many runways were there, and how long were they? Does Brisbane have more airlines flying there today than it had back then?
