The big lettering on the dark painted MiG's reads, first line 'China', second line 'people's volunteer army air force'. I've never seen any reference to such obvious lettering (readable or not by US pilots) in numerous US accounts of various markings on MiG's. It seems possible it was just for publicity photo's when that big. Most Soviet MiG's in Korea carried NK markings, as did the relatively small number of NK MiG's, naturally; Chinese a/c sometimes carried Chinese markings (in terms of the details of the red star).
killed. I don't know of any PLAAF claims that day, there were 4 Soviet claims (just Asla's F-86 was lost).
