Yes, you can´t help thinking that it might be some tracers after the pilot in the middle. I saw on youtube a interview of a surviving Kamikaze pilot, he had actually been on one mission.
They carried parachutes, and was ordered to return if possible if no targets where to be found. This guy in listed totally as a volunteer. By the time he was old enough , being a pilot was equal to die anyway, so he felt he could do more by being a kamikaze pilot. Anyway he was intercepted by US fighters and bailed out when his VAL was hit.
Lately there are questioned wether the Kamikaze pilots actually was "volunteers" . Trained pilots diaries tells a different story, when "asked" they had a enormous pressure to answer yes, and felt it like disgracing their family by saying no. The matter in fact almost 100% of those writing down their feelings , and already served as a pilot. Did not agree that kamikaze was the best way to utilize their capacity, they was convinced they had better things to accomplish as a regular pilot.
