答案 八年级地理上册填图题岩土工程勘察试题省略号的作用及举例应急救援安全知识车间5s试题及答案 ，但其中也不乏令人感兴趣的研究理论。一些科学家和通俗读物作者甚至提出，这一海域是外星生物的狩猎场，为其“巨大的动物园”来搜集人类的标本。不管到底是什么原因，经过这一海域的飞机和船只仍然奇怪地有规律地消失。1947年7月3日，一架美国陆军的C54型飞机在距百慕大100英里处消失，此前没有发出任何危险信号。在随后进行的对方圆10万平方英里海面的搜寻中，没有找到任何飞机的残骸。1948年1月30日，一架英国飞机又在该海域上空消失，机上有31名乘客和机组人员。一年之后，一架飞往牙买加的英国飞机在途经该海域时失踪，72架飞机和几十条船前去寻找，也是一无所获。被这片神秘海域吞噬的最大的船舶之一是美国一条500英尺长的海岸警备船。它在1918年3月4日失踪，调查

明，当时气象条件正常，失踪时没有呼救，也没有发现失踪船只的残骸，船上的309人也不见踪迹。更加奇怪的是，这片区域中有许多没有船员、四处漂浮的“鬼船”。在1881年发生的一件奇异事件中，埃伦·奥斯汀号货船发现了一条二桅帆船，随风漂流，整条船没有损害的痕迹，但也没有人的迹象。埃伦·奥斯汀号的船长派出一组船员去驾驶这条船，但是两天以后，在一场暴风雨中，两条船彼此失去了联系。当船长再次登上这条船时，发现他派出的船员也失踪了。从官方角度而言，美国海军方面并不承认百慕大三角是一个危险的区域。美国海岸警卫队坚信“这一地区的大多数失踪案件可以归因于这一地区独特的环境特征”，这包括湍急的海湾水流、大西洋底尚未探究的峡谷和该地区恶劣的气候条件，这一地区也是世界上仅有的两个指北针指向真正的北方而不是电磁北方的地区之一。因此，如果一个航海者忘记了这一点，也许就会偏离航线。发行3个月后销量就达到50万册的《魔鬼三角》一书的作者理查德·瑞曼写道：“这里有很多神秘而奇怪的事情，但是我相信这些现象真正的答案就在于人们自身的错误、仪器的失灵、天气的误报或者电磁场的异常。”美国国家海洋与大气管理局的官员对该地区怪异现象的解释则并不那么肯定。它的报告说：“尽管美国海、空军和海岸警卫队付出了巨大的努力，但到目前为止，对该地区的失踪现象尚无一个合理的解释。”由于这些不确定性，私人的调查人员开始寻找更可信的解释。《神秘的失踪》一书在出版后的15个月内，销量就达到了150万册，其作者约翰·华伦斯·斯宾塞认为：外层空间的生命已经在大西洋中这一未曾探测的三角区域的海底建立了一种更加先进的文明，他相信在这一文明之中，大多数失踪的飞机、船只及人员都陈列其中，以供更智慧的生命研究之用。他承认，“这听上去有些奇怪，但当你认识到这是对所有失踪事件的唯一解释时，就不会感到奇怪了。”理查斯·伯利兹在《百慕大三角》一书中对上述理论以及其他一些理论进行了研究，该书在出版后不到3个月的时间内就登上了畅销书的榜单。作为一名耶鲁大学的毕业生，伯利兹对传说中失踪的亚特兰蒂斯大陆极有兴趣。他创立了一种理论，认为有一个巨大的来自太阳的石英晶体位于百慕大的海底，它曾向亚特兰蒂斯大陆提供能量。他的理论认为，过往的船只和飞机会启动这个石英晶体，它会误导这些船只和飞机的仪器，将它们吸入深不可测的海底。TextComprehension
