Secret Air base out from Marble Bar
Hi RallyDog, I believe that would be Corunna Downs, I visited it around 1986 when I was at Tom Price.
Incredible history there as with all the bases during WW2.
I used to skydive at wartime strip built by US Army in 42 on Hillman Farm near Darkan south of Perth. Our clubhouse was Nissan Hut.
Cheers.
