All who was common in that time with magazines from Sovie Unio could with easy read all of this. Almost two decades ago I have list of the leading aces from this theatre. Hope that author have given good search and some interview with former pilots. Many things are maybe still unkown. Some time ago I was send to one friend a image of the MiG-15 during air refueling from Soviet copy of B-29 and he was surprized as well he did not know at all that Soviet have that capabilities. Excellent ocasion to get more info about this fighter was escape of one pilot from Korea... well know story.
