Some fictional history:
The C-31 was an aircraft capable of operating different roles, roles such as fighter, bomberhunter, light bomber, etc. It first flew in 1940 and was retired in 1954. These aircraft were also used to load supplies (especially food) and drop it to civilians and allied soldiers in difficult situations, situations like what happened in Stalingrad.
