Lossie has plenty of room!
In the good old days Lossie had:
12Sqn Buccaneers in the Northern HAS
208Sqn Buccaneers in the Southern HAS
237 OCU on Alpha and Bravo
16Sqn Jaguars on Delta
8Sqn Shackletons on Charlie
That still left Lima available for visitors and exercise traffic of which I've seen upwards of 20 aircraft parked on,including Canberra's. They also used to use infront of hangar 1 for visitors when VASS was situated their. Plenty of hangarage still available and as already mentioned 2 decent sized operational runways.
