Another short clip from the NHK collection featuring Mitsubishi G3M2-a Model 21 "Nell" bombers, similar to the previous posting, here. While in the previous posting the bombings of Chonqguing took place on July, the Japanese bombers in this video are taking part in bombings against the city in August 1941. In the beginning of the video we see the briefing of the crew members regarding their targets within the city. From 0:22 we see two high ranking officers. The one mentioned in the video, next to the unknown one with the white uniform, is Admiral Shimada Shigetaro, who as Wiki correctly mentions, was serving as "commander in chief of the IJN 2nd Fleet and China Area Fleet."
Note the G3M2-b at 0:58 and the G3M2-a at 1:05 and the green/brown camouflage pattern of the latter which has the code number "K-357" on the tail. The "K" would indicate that it belonged to Kanoya-ku which used this marking from November 1940 until September 1942.
