Something wrong with our data. According mine, the two commander pilot's names were: starszyj let. W. Starostin and second was G. Sawczenko (Savchenko). One name is overlaping with your.

I think that it was MBR-2 crews in secret mission behing Finnish territory, they had to drop agens/diversants, lost on 29.07.
In this period it should be no SBs of NKWD's units on the front, only see zvieno.

BTW
Commander of whole 11, OAE was major Pietrov. He flown on SB and took part in bomber mission. SB since 22.06.41 were sent on German units in Latvia, later over Russia. The last combat mission was done on 7.07.41. Since 1.07.41 SB took of to the action from Wechna (Vehna) airfiled and later from Staraja Russa. The base was too far to Finland already on 7.07.41.
