Mechanical paper of 5 VA, 207 OKRAP lists two (Omsk, Factory No.166-built) Yak-9D and one IL-2KR recce. plane loss between November 1-15, 1944. Chances are these 3 planes were the losses on October 27, 1944 as prev. days' losses - depends on how long investigation and paperwork took:

IL-2KR, S/N: 10948, AM-38F engine: 256676
Yak-9D, S/N: 19166066, engine: 415-1037
Yak-9D, S/N: 19166078, engine: 415-90

So it looks like the 4 airmen lost on October 27, 1944 flew 2 Yaks and one IL-2 indeed. This is based on the plane info only, no combat details, even if their names are known.

Both La-5 and Yak-3 pilots survived the battle and were taken POW.
