Both messages are Russian names: Vasily Reshetnikov (flew 307 missions in WWII mainly as a pilot for a long-range bomber, Hero of the Soviet Union) in this picture and Alexander Novikov (Chief marshal of the aviation for the Soviet Air Force, involved in nearly all exploits of the air force during WWII, twice a Hero of the Soviet Union) in Wikipedia.
Probably these texts are the names of persons notable in Russian aviation (not necessary pilots). They are different for different planes.
