The rumour is that DD still sleeps in one of those tents when he stays overnight after Board meetings. No perks for BRC people.
Re the airport, the Yanks eventually built a set of large hangers, about 5 as I recall, on the left of the main runway in the pic. That was the end of the Straight Six. At the end of the war, the airport remained as Brisbane's commercial airport with TAA and Ansett taking a hanger each. Qantas may have also taken one for the very occasional international flight but I cannot recall. They sure got their return from those hangers because they were used from the late 1940's until the new Brisbane terminals were built in the 1970's.
Will try a Google search to see if there are more pics in the archives of those airlines.
