Step-by-step explanation:
The question about the aircraft flown by Steve Preston pertains to a specific figure in the history of aviation. However, based on the information provided, it seems there might be a mix-up with the name 'Steve Preston'. The details given reference 'Stepanovich' and other keywords such as 'aircraft in posters', 'parachutes', and 'Stalin's falcons' (pilots), which suggests a historical context, likely involving the Soviet Union's aviation history during the Stalin era.
