This I extracted from WW2 aces website. Is an extract of a serie of relates by Satoru Anabuki japanese ace with 51 kills.
If this is an actual event or not I will let to your opinion.
Anabuki's greatest deed happened on October 8 1943, when at 12:10 hs four Hayabusas (one of them flown by Sgt Anabuki) taxied in Mingaladon airstrip to take off and intercepte several B-24s which were raiding against a Japanese convoy in Rangoon harbour. However, a fouled spark plug caused that Anabuki should delay his take off during 5 minutes. When he finally could scramble, was unable to find his three buddies and a second flight of four Ki-43s (which were also tasked to intercepte the bombers) because of the haze. Suddenly, when he got out of the hazy area, saw his target: 11 B-24s together with two escorting P-38s, which apparently did not notice him.
Anabuki realized that -due to the hazy weather- none of his comrades had found the enemy and that he was completely alone. But Anabuki also noticed that he was in a perfect attack position against both the enemy fighters and bombers, and the surprise factor was at his side. Being a hunter by nature, Anabuki decided to take that chance despite the odds were against him.
So, Anabuki choose one of the unaware Lightnings, put it in the gunsight of his Ki-43 Hayabusa and badly shot it up (Anabuki saw the incendaries exploding around the P-38's cockpit), breaking his attack and diving only when he almost collide the American plane. As he turned to repeat his attack, saw the P-38 trying a loop while leaving a trail of black smoke. Suddenly the P-38 stalled and went downwards, crashing near Yangon river. Then Anabuki jumped the P-38 leader, but his adversary was an experienced pilot because it immediatelly rolled and steeply dove. Knowing that his Ki-43 Hayabusa was excellent in dogfighting and could out-turn the P-38, but could not compete with the Lightning in dive and climb rates, Anabuki did not even try to follow the American plane, instead he concentrated in the bombers.
"All I could see was the enemy. I'm diving straight down towards the dark jungle. Life or death didn't matter then. If the gods still need me they wouldn't let me die. I see an image of my mother's face. I think I heard her yelling `Go, Satoru,go!`. I think of what a strong woman my mother is. I think to myself I must be as strong. Distance closes further. 300, 200, I see my bullets get sucked into the gigantic B-24. Getting closer. 150, 100. I start firing my final burst.
The enemy's defensive fire is fierce. Their formation is trailing a lot of gun smoke, raining bullets in successive bursts, but I know as long as I'm at this angle, they can't hit me. My target starts smoking from the wing root. Even as I'm firing, the white smoke is getting bigger and bigger. I'm near collision and I break off to the left and to the rear of the enemy, diving vertically. Fifty some enemy machine guns are firing at me, but not a single bullet hit me as I speeded away out of their range. "
When Anabuki prepared himself for a second pass against the badly hit B-24, saw that it slipped at one side, the crew bailed out and the bomber began to spin. So, in few minutes he added one P-38 and one B-24 to his killboard.
But when he was ready to attack the bombers for the second time, suddenly saw tracers passing very close to his port wing. Anabuki sharply broke to starboard, avoiding the burst, but a second one struck his plane, being the Japanese pilot badly wounded in his left hand. Anabuki realised that the P-38 leader which had previously escaped was back, and it was willing to take him out. Despite the intense pain, Anabuki performed a series of the sharp turns, exploiting the superior turn capability of the Ki-43 Hayabusa and forcing the American pilot to gave up. When the P-38 pilot did so, Anabuki rolled his plane and reversed towards the Lightning. At point-blank range (about 30 mts) the Japanese ace fired and black smoke emerged from the P-38, together with oil which splattered over the windshield of the Ki-43 and temporarily blinded Anabuki. When he recover the sight, the P-38 was diving away again, this time definitively.
The history continue. But to make not the post too long conclude with satoru ramming ( and bagging) another B-24 and bailing out.
