航空界裡的祕密,天空到處都是UFO 宇宙中人類是唯一的智慧生命嗎?愈來愈多的証據顯示,外星人是真實存在,且與人類的互動頻繁。加拿大前國防部長鮑爾•赫勒(Paul Hellyer)說,地球上至少有地球上共有2種到12種外星人,有的像人類,也有的長得像如漫畫中的生物形象。 外星人是來毀滅或解救地球? 幾千年來,外星人不斷到訪地球。他們是帶有惡意的侵略者?單純的研究者?還是善意的警示者?外星人們不是同一種群體,而是不同種類的生物,大部分外星人對人類懷有善意,但是有些外星人的目的是邪惡的。 世界各地每年有數百個不明飛行物報到,英國愛丁堡的科學家們對外星人存在機率、太空飛船建造和星際間旅行時間進行計算後,得出結論顯示,其實外星人的探測器早就伸向了我們,密切觀察著人類,外星文明可能比我們人類發達幾千倍甚至幾百萬倍以上。 但最引人注目的外星人證據是在美國領空。許多證人看到了這些不明飛行物。1997年3月「鳳凰燈」事件,在3月13日晚超過100名證人站出來,說看到三角或’V字形狀的機器在亞利桑那州 菲尼克斯市徘徊。百分之五至百分之十的美國人口已經看到了他們口中的飛碟。美國也擁有最高紀錄的綁架外星人記錄。 X檔案真實上演 地球人遭遇外星人綁架的故事屢見不鮮,有些被綁架的人說,他們和外星人之間發生了令人興奮的心靈感應,那是一種愉悅、溫暖的經歷。還有些被綁架的人說,外星人強迫他們接受科學實驗或手術。 美國一直與外星人合作發展科技,卻否認他們存在 登陸月球的美國太空人米切爾( Edgar Mitchell )以他在太空總署工作多年的日子,掌握不少鮮為人知的內情,清楚知道外星人曾多次派UFO前來地球,並試圖跟人類接觸。米切爾坦言: 「我曾在軍事和情報部門工作,知道的比公眾更多,我可以答你,外星人來過這。 」作為一名太空權威專家,言論份量十足。 美國政府一直以來隱瞞了關於外星人的祕密,一個被礦坑掩護的美國空軍禁區「51區」,也是美國政府從未承認其存在的軍事禁地,卻具有讓美國政府和五角大廈直接管轄的身分!相傳,在這兒,包藏著美國高科技軍事武器與計劃的秘密!也是隱藏著許多外星人與美國政府不可告人的合作協定。 NASA為何配合美軍隱瞞外星人資訊? 外星人和美國政府達成了什麼協議? 見到飛碟的證人被FBI恐嚇最好閉上嘴巴,否則會讓他們惹上殺身之禍? 18名外星人取得公民為美國政府做事? ...
