thanks for the pics muffett.
there is a T-6 and a stearman? (in naval colours) at the local airport that i see flying at least once every two weeks, but the sound of a BIG IC engine will still draw me out, looking at the sky, every time.
back in the early 90's i was on a beach in the bush south of sydney when a single macchi came booting along just off shore at about 150 - 200' above sea level on a perfect summers day. the image will stay in my mind for ever.
