A new aircraft type for me was this LAC Prospector E.P.9. Originally designed by Edgar Percival, ZK-PWZ is one of only two left flying in the world. The type was originally designed and operated as a top-dresser, although it is now fitted out with six seats.
It has to rate as a fairly ugly aircraft [or should that be "functional"???], but it was a good display, and it's great to see extremely rare aircraft still being displayed in the air, rather than confined to the ground.
