Secret FBI files have been released detailing how US officials saw a UFO explode over Utah – and aliens land near Roswell in New Mexico.
美国联邦调查局（FBI）近日解密了一批文件，其中详细记录了美国犹他州不明飞行物（UFO）爆炸事件，以及新墨西哥州外星人着陆的“罗兹威尔”事件。
A declassified document from 1949 tells how three men, on patrols miles apart, each reported seeing a UFO break up over mountains north of Salt Lake City.
一份1949年的解密文档称，当时有三名相隔数英里的巡逻人员都报告称发现一架UFO坠毁在盐湖城北部的山间。
Their extraordinary accounts were sent to Edgar Hoover, the director of the FBI, in a memo titled "Flying Discs".
这些非同寻常的陈述被呈报给时任FBI局长埃德加 胡佛，这份备忘录名为“飞盘”。
The file said that a policeman, a highway patrolman and an army guard all "saw a silver coloured object high up approaching the mountains at Sardine Canyon" that "appeared to explode in a rash of fire."
备忘录称，当时有一位警察、一位高速公路巡逻员、和一位卫兵都看到了“一个银色飞碟在高空中向萨丁峡谷的山间飞去，似乎突然起火爆炸了。”
"Several residents [reported] seeing what appeared to be two aerial explosions, followed by falling object," it said.
文档称：“据报道，几位当地居民都曾目睹两次空中爆炸后飞碟坠毁。”
