Gabor, thanks ! Very interesting !

Yes, it is very likely that downed Il 2 and two Yak 9 were part of the 207 OKRAP.
May be able to find more information about the events of that day, knowing the name and surname of dead pilots (eg. databases WWII losses or other sources) ?

Two other plane (La 5FN and Yak 3) were also lost in combat missions? The pilots of these planes were lost ?

Best Regards,
Alfred
