I don’t think there is anything particulary sad about having a Stearman in your logbook 😀
I can fully agree, that having flown more than one type only goes to expand your horizons. I’ve got 30+ types at the moment in my logbook, and every single one has tought me a little something about flying.
Absolutely, I also agree with what Propstrike said about flying by the picture rather than the numbers. The case of 172/Stearman is exactly that. You cannot compare the numbers or even the view but the ‘picture’ should remain the same.
There are others that I have blagged and forgotten, I have also flown a Minicab (cramped), I once thermalled a T21, have a couple of gliders dual including some string time, Stinson Station Wagon and there are a few more that I have flown in. I have not flown a Stearman yet but I have take a lot of pictures from one!
