I rattled my teeth to the dentist, thank you for asking.
AN-2s are regular here. One does sightseeing city tours. I see some on the sea-side, too, doing tourist flights, I think they are Polish.
I find the sound rather soft, a bit like there were a lot of liberal tolerances. That's why they are so durable, I think.
When I was 10 - 12 years old, Soviet Mig-15s often draw contrails in the shape of 8 over the town I lived in. Given the fact that it was not Soviet airspace, there was always a debate between the officials and the public if they were in fact made over the sea and drifted, or plain made on our space. Nothing to send to scramble and find out…..
