The Cockpit (OVA) - Plot - Sonic Boom Squadron

Sonic Boom Squadron

On August 5, 1945, a Japanese force of Betty bombers, each carrying an Ohka and escorted by N1K Shiden fighters, attempts a raid on an American aircraft carrier battle group in the Pacific Ocean. As the raiders are attacked by American carrier-based aircraft, Ensign Nogami, a young Ohka pilot, demands to be launched in his Ohka, but his Betty's crew refuses. The bomber is destroyed, throwing Nogami into space. He survives the failed raid and is able to return to base, where he meets the crew of the Betty who will fly him on a mission the following day, as well as two surviving Shiden pilots who vow to help him succeed in his mission if it costs them their lives. On board the American carrier, the pilots receive news from their captain that the attacking Betties were carrying Ohkas.

The next day, August 6, the Japanese attempt a second raid on the same battle group. An intense aerial fight ensues as the American carrier aircraft attempt to thwart the raiders from launching their Ohkas. Nogami's bomber is heavily damaged and almost destroyed, but is saved by the intervention of one of the Shiden pilots, who crashes his aircraft into a pursuing F6F Hellcat. This enables the bomber to get within visual range of the battle group, and Nogami is launched in his Ohka just before the bomber disintegrates. He flies through a wall of anti-aircraft fire thrown up by the escorting vessels and crashes into the American aircraft carrier. Just before the carrier explodes, the battle group's commander receives word that an atomic bomb has just been dropped on Hiroshima.
