Yeah! The 'Colt' is something special. The fact that it's a HUGE biplane and made in vast numbers pales in comparison to it's slow-flying capabilities! I did see one at a small airshow at Sandefjord Airport,Torp a few years ago. I came 'puttering' along the runway on a lowpass so slow, that I expected it to just fall out of the sky. It's so delightfully russian . Big, crudely made, noisy, odd and performs almost "above and beyond" (Not in the high-speed category, though!).
