LoBelly,
Funny you should say our Air Force. The Bi - Planes are actually owned by the RAAF museum staff who regularly take flights from the Point Cook Air Base.
We just did not have time on the day to do either a Bi - Plane or Mustang flight in the old Warbirds..

Well worth a visit when in Melbourne. Just ring your tour organiser..
