Hi thanks for long post
Sorry but I do not write Russian, but read and speak a little.
Some errors in your post.

Откуда у Вас в книге появилась цельная ТЫСЯЧА БОЕВЫХ САМОЛЕТОВ????
1. I did not write that Lotnictwo Wojskowe had on the 1-st line 1000 but it is written that VVS RKKA had used activly about 1000 combat planes of about 3300 gathered on 17 IX 39. It was enough for such small + short air war.


Среди Советских войск тоже настроения были не агрессивные...
2. There are many Polish memories from KOP or other land forces soldiers, who confirmed of being under attack of VVS RKKA (like: 22, 24, 30 IX or 1 X). The last Russian air attack against was done on the begining of X 1939 (against soldiers of SGO Polesie).

There are of course more VVS RKKA air attack done in this 2-3 weeks. The last combat reccon of VVS RKKA was reported on 7 X.
I have written about this too.
As you know official Russian losses figures of 17-30 IX are given about 1500 (KIA, KIFA, DoW) + next 2000 wounded. Russian were not killed, wounded by plenty of thrown "flowers, apples and potatos" by Białorussian and Ukrianinans + Jews. They lost their life mostly in combat against Poles in this period.
BTW: There are on the book the list of 11 Russian VVS RKKA crew's members killed during this war - all reason.

There are of course information about this R-XIII and other 5 Polish planes "captured" by Russian in 13-16 IX. These planes rather strayed (like this 3 P.37 on 13 IX) and did not made any "secret" reccon. Polish crews had orders to fly to the south-east part of part of Poland and rather lost orientation, then made such deliberatly reccon.
Second Poish plane, you should know from this document, had escapted to Poland was "PWS-26" . This was not standard plane in any 1-st line reccon units (like R-XIII + RWD-14) - but was from training unit. It menas both plane were from training school and were not from combat one.

Some of Polish crews from these captured Polish planes (13-16 IX) were later killed in "Katyń" - the names are given of course.

On East there were on 17 IX still about 150-170 Polish combat planes (low quality of them; lack of fuel, ammunition, field workshop) + next a few hundreds civil and training planes. Part of them had escaped to Romania (about 300: military, civil, training) + to other countries (like about 90 to Latvia).

"not so many air combats" (не так много)...
Sorry, but you do not undrestand my words. In fact it means it was a few air clashes/ or air combats, or not so many. About 3-7 air combats. Which 3 could be sure, next not so but probably. So again not so many. Mostly Polish plane were shot by Soviet A/A. The same danger was for Soviet planes, which were often shot by onw A/A unit.

NKVD + GVF Aerofłot
NKVD had used a few zvienos of separate escadrlia (they had R-5 or U-2) for liasion (sviazi) flights, no direct military combat. Maybe it will be surprise for you but border NKVD units was subordinated to commnad of land RKKA. Border units were on the top/"leaders" of land attack along whole Soviet-Poles border. They took active action in 17-19 IX along whole border.

You should know that GVF was planed for war as an air transport units. Such planes like P-5, or G-2/ civil TB-3 had transported mail, food, newspapers, soldiers, wounded etc. to the military zone and operated as support aviation. RKKA had recived about 160 tons of such things in this war.

Так, 1 октября по иказу командующего самостоятельной оперативной группы "Полесье" генерала Клееберга командир приданной группе 13-й разведывательной эскадрильи капитан Э.Перункевич вместе с поручиком К.Радзивиллом производил разведку дислокации гитлеровских войск на самолете ПВС-26. После выполнения задания разведчик подвергся нападению трех "мессершмиттов". Разведчик не был вооружен, а летчики не имели даже парашютов. Но отвага и летное искусство капитана Перункевича не позволили немецким истребителям уничтожить польский самолет. Эдмунд Перункевич стал последним польским пилотом, выполнявшим боевые вылеты (вплоть до 5 октября) в Оборонительной войне 1939г.
Fany but story is semi-true! In fact PWS-26 was attacked by 3 I-16s. It was
the last air comabats on 1 and later was second on 3 or 4 X, when Soviet "3" I-16s had atatcked the reccon PWS-26 of SGO Polesie. The memories of Piorunkiewcz was edited in 1960 (censorships/ ban to mention that was any Polish-Soviet war in 1939 up to 1988), There are not mentioned any "Me 109" - only the attack of enemy planes I have his memories in my archive). In 90. was edited memoreis of famoues Polish aviation constructor T. Sołtyk, who from the ground did observe this particular air combats. He was professional aviation constructor in PZL (before 1939 and up to 1970). He told in his memories that PWS-26 was under attacked of "Ratas"/I-16s.

Summary
So all these from links below are well know for me (Mieltiuchov from the second edition not from 2001 but from 2004 - quite bigger one). There are in my book many, new information based on: Soviet, Poles archive material/ reports, documents orders etc, plus many memories of Soviet, Poles soldiers, who were there and fought themselves.

Book is written to present this rather small known chapter of air war in 1939. Materials are such much corssed from both side as I could do this. Studing this subject for many years I know it quite good and deep
