The highs and lows of a B-29 (all surfaces shredded but still flying) and its crew, eventually shot down by Zeros and by a Ki-45 over Tokyo.
Note at the time of the action some B-29s still had a 20mm cannon in the tail. The tail armament was then modified to all 0.50 calibers in line with all other gun turrents of B-29s. The common 0.50 caliber made ammo logistics/provision and reloading much easier.
