Google Earth 拍到疑似美軍曙光女神偵察機飛躍俄羅斯上空
http://wforumfans.50.forumer.com/download/file.php?id=154&t=1曙光女神(Aurora,據稱其正式編號為SR-91 Aurora),為美國航空界和軍事界最負盛名的傳說之一,據說此機種為美國研發的高超音速偵察機。目前外界推測曙光女神最高時速可以達到6倍音速,飛行高度達到了3.88萬米,在1980至90年代服役取代日漸老朽的SR-71黑鳥式偵察機。英國國防部在2006年6月的報告指出美軍在生產計劃優先順序中計畫生產速度4~6馬赫的極音速偵察機[1];2007年9月,美國空軍與國防高等研究計劃局簽署諒解備忘錄[2] ,內容為製造最高速度可達六馬赫的無人機,此台無人機的名稱為Blackswift。但美國軍方至2006年一直否認它的存在,雖然大量航空愛好者目擊或拍攝到可能是曙光女神的形象。
