Shown here is a frame from a Japanese cine film showing a A6M2 Navy Type O Reisen (Zero Fighter) Model 21 (foreground) and B5N1 Navy Type 97 carrier Attack Bomber Model 11s ranged on the deck of a Japanese carrier early on Sunday 7th December, 1941: destination, Pearl Harbor. The US Navy caption gives the carrier as the Hiryu but the insignia are not those of the 2nd Sentai.
