其他的轰炸机也都负伤, if so, after 志愿军空军击落美军空军飞机3架, there were still around 30 架美军空军飞机. How could the following had happened?

我轰炸机群仍然在坚定地向着大和岛挺进。(although 也都负伤) 　
　　终于，我机编队飞到了大和岛上空，复仇的炸弹似瓢泼的大雨倾泻了下去。敌人的巢穴随着剧烈的爆炸声化作了一片火海。 　
　　大和岛收复了。我带队长机庄重地下达了命令：“左转返航！”机群越过渐渐散去的硝烟，迎着太阳飞去。

I just do not believe such dramatic results. Do you?

P.S. I am sorry that I could not type Chinese on this computer, so, I have to reply in English mostly.
