The U.S. believes the Ukrainian plane that crashed shortly after takeoff from Tehran, killing all 176 people on board, was shot down by two Iranian missiles, a U.S. official said. A U.S. official familiar with the matter said Wednesday that data transmitted via satellite indicated everything was normal on the jetliner until the sudden loss of data and the fatal dive. That data suggest to some U.S. air-safety officials that there may have been some sort of hostile act, said the person, who also cautioned that it was too early to draw conclusions. wsj的报道里这么说的。详情未知
太惨了。casualties of a staged war and all the reckless players.....
CBS news U.S. intelligence picked up signals of a radar being turned on, sources told CBS News. U.S. satellites also detected two surface-to-air missile launches, which happened shortly before the plane exploded, CBS News was told. Federal officials were briefed on the intelligence Thursday, CBS News transportation Kris Van Cleave reports. A source who was in the briefing said it appears missile components were found near the crash site. The plane was believed to have been mistakenly targeted.
但是涉事客机的2个黑匣子已经找到，伊朗拒绝交给波音公司或美国，这起空难事故的相关信息越来越多，六大疑点浮现。
疑点二 客机是否存在机械故障？ 据伊朗伊斯兰共和国通讯社报道，伊朗道路与城市建设部通信与信息中心负责人卡西姆·比西在事故发生后表示，失事客机发动机出现故障导致机身起火。 据《商业内幕》报道，有航空专家指出，发动机故障是商用客机常见的问题，可能会使零件分解，损坏机体，但一般情况下不会导致坠机。 根据乌克兰国际航空公司网站信息，涉事客机已服役3年半，事故发生的2天前刚进行过一次技术检查，没有发现任何异常。乌克兰飞行安全基金会的记录显示，乌克兰国际航空公司在此之前没有发生过空难。 尽管波音737MAX此前在5个月内发生过2起坠机事故，共造成346人死亡，该机型已经在全球遭“封杀”。但是此次涉事客机为波音737-800，是单通道、双引擎喷气式客机，用于中短途飞行。该机型于上世纪90年代末推出，比波音737 MAX机型更老。这架客机属于737 NG系列，全世界有逾8000架同系列飞机在服役。 乌克兰国际航空8日在一份声明中表示，将无限期停飞德黑兰航班。公司正在尽一切努力找出失事原因，将对罹难者家属提供所有可能的协助。 疑点三 飞行员是否存在操作失误？ 据CNN报道，乌克兰国际航空总裁迪赫涅拒绝就飞机失事原因发表评论。在乌克兰首都基辅鲍里斯波尔国际机场举行的新闻发布会上，该公司运营副总裁伊戈尔·索斯诺夫斯基说：“我们得到的消息是飞机爬升到了2400米的高度。机组人员操作失误的可能性很低，我们基本上不认为是操作失误造成坠机，因为驾驶人员都很有经验。” 飞行机组人员包括三名飞行员，机长Volodymyr Gaponenko拥有11600小时波音737飞行时长，其中5500小时担当机长；飞行教员Oleksiy Naumkin拥有12000小时波音737飞行时长；副驾驶Serhii Khomenko，拥有7600小时波音737飞行时长。 疑点四 乌克兰驻伊朗大使馆为何更改声明？ 在坠机事故发生后，乌克兰驻伊朗大使馆表示，坠机是技术引擎故障所致，排除恐怖主义和导弹袭击的可能性。希望能够搜集到更多具体证据。
