Hello Kirill,
yeah.
To resume the original topic:
As far as I understand that website with my very limited Russian skills
http://airaces.narod.ru/all14/shamanov.htm
the connection of Ivan Shamanov to the Douglas A-20 is explained like this:
- the Ilyushin and the Douglas were available at his unit
- Shamanov scored 8 kills
- it's not known if these kills were scored by him personally or by his crew
- in the former case he might have been flying a Douglas because the Ilyushin has no guns for the pilot
Have I understood it correctly ?
