1943年5月16日夜间,盖·基布逊中校率领19架“兰开斯特”重型轰炸机飞越已被纳粹德国占领的欧洲海岸线,执行一项秘密任务。出发前,机组人员都经过了长期的特殊训练,飞机也进行了改装,挂载由巴恩斯·沃利斯设计的桶状炸弹。当机群渐渐逼近目标时,轰炸机开始鱼贯超低空飞行,在18米超低空高度投下桶状炸弹。当飞机完成投弹动作拉起时,飞行员能够看到炸弹以500转/分的速度自转,从水面上跳跃前行,巧妙地躲过了大坝防雷网的阻拦,触坝后迅速滚入坝底爆炸。 On the night of May 16, 1943, Lieutenant Colonel Guy Kibson led a fleet of 19 Lancaster heavy bomber aircraft flying over the European coastline that was occupied by Nazi Germany to carry out a secret mission. Before departure, the crew members had undergone special training for a long time, and the aircraft was also modified to carry barrels designed by Barnes Wallis. As the fleet approached the target, the bomber began flying at very low altitude, dropping barrel bombs at an altitude of 18 meters. When the aircraft completed the bombing action, the pilot was able to see the bombs rotate at a speed of 500 rpm and jump forward from the water, cleverly avoiding the blockage of the dam lightning protection network and quickly rolling into the dam after touching the dam The end of the explosion.
