人类的连体双胞胎一般要用外科手术冒很大风险将他们分开。而在作战飞机的研制中,却有人专门将现成的两架单机硬连在一起以提高战斗力,二战末期德国巨型He 111轰炸机与美国的P-82“双野马”远程护航战斗机就属此类。当时将2架He 111轰炸机用中间翼段连接起来,是因为德国急需远程轰炸机,而研制全新轰炸机成本过高,时间也来不及。美国北美公司也是为了节约时 Human Siamese twins generally use surgery to take a great risk and separate them. In the development of combat aircraft, however, some people specifically devote themselves to two stand-alone hardlinks to improve combat effectiveness. In the late World War II, the German giant He-111 bomber and the U.S. P-82 “Twin Wild Horse” long-range escort fighter belonged to this class. At that time, two He 111 bomber planes were connected with the mid-wing because of the much-needed long-range bomber in Germany and the time-consuming development of new bomber aircraft. American North American companies also save time
