In the 1960s (Vietnam) more accurate bombing systems allowed the same target to be destroyed with 176 jet fighter- bomber (F- 4 Phantom) sorties,each carrying one bomb (half of which would land more than 400 feet from the target).

• 在60年代(越战期间)，由于使用更为精确的轰炸系统，摧毁同样目标只需出动喷气式战斗轰炸机(F-4“鬼怪式”)176架次，每架飞机携带1枚炸弹(其中一半炸弹偏离目标400多英尺)；
