Jeremy, On his victory on the 09 Nov 1942 I found the following. From 15:00-15:55 (Moscow) 4 Yak-7 of the 271 IAP were covering the front in the region of Zemtsy station - Lomonosovo station. At 15:30 they observed a He 111 and all of them attacked making 8 passes before it went down in the Ostroluki region. It seems they became to focused on their attack and it ended at 15:40. Yak-7 (#820519) on board #1 St. Lt. Georgiy Dmitrievich Pupov was listed MIA on the rest landing.
