Malaysia’s Transport Ministry also said that three civil aviation security officials had arrived from France to share expertise gained from the search for Air France Flight 447, which disappeared nearly five years ago off the coast of Brazil. Searchers there needed almost two years to find the Air France jet, an Airbus A330, on the floor of the Atlantic Ocean.
Australia is a world leader in over-the-horizon radar technology, with the Jindalee Operational Radar Network covering around 37,000 square kilometers, or 14,285 square miles, across Australia’s northern and western boundaries and out into the Indian Ocean. Andrew Davies, a senior analyst at the Australian Strategic Policy Institute, said that conventional radar requires a line of sight to an aircraft, but that over-the-horizon radar bounces high-frequency radio waves off the atmosphere.
Dr. Davies, who also worked at Australia’s Department of Defense as a capabilities and intelligence analyst, said that the JORN system has the capacity to monitor flights into the Indian Ocean. “But a lot depends on the atmosphere at the time,” he said, adding that a satellite may also have been overhead, but that satellites must be “tasked to look down” on a specific area.
“It is entirely possible nothing was tasked to look at this part of the world,” Dr. Davies said. “The over-the-horizon radar might not have been effective because the aircraft was out of range, or the atmospheric conditions were not right.”
Satellites cannot be active for their entire orbit, Dr. Davies added, as they must shut down to recharge batteries. “If there is no reason to look at a box of ocean, it is entirely plausible that no one is looking.”

马来还做戏做全套阿
也许早就有进来过的，人家敌机进来看看就走了，没有任何consequence。。。。。。
怎么感觉亲妈还是什么都不知道，怎么找啊
其他国家在这个事件中是被动得不能再被动了吧，信息&搜寻范围都被限制/控制。

就连这么牛x的radar system都啥也没发现。。。。。。。。。。。。。。。。。。。。。。
该查看啥赶快趁机会查看了
如果一直听着马猴瞎指挥
铁定转悠不到真正的位置啊
多走走多溜溜，能兜点什么兜点什么。
但是话又说回来，极端穆斯林洗脑的功力也确实非同凡响~~~啥东西一极端就麻烦，偏偏还有人信得死去活来~~~参见李“大师”~~~高知啥的信“大师”也不是个别~~~
别说，前两天还真有个新闻说一个20多岁的姑凉通过一个美国特工的合同工获得大量情报，合同工当然被抓了，姑凉消失鸟
昨天看cnn还是前波音某专家科普说为什么南印度洋更可能，是说巴基斯坦确认说没发现飞机信号，也就是说飞机不可能绕过印度，从巴基斯坦北上。只有通过Bangladesh 经喜马拉雅山北飞，难度巨高。
今天看另一分析，说美军在印度洋有多个军事基地，往南是澳大利亚，无论飞机是langding还是crash在南印度洋，而不被发现更难。
而现在美国实际是从安达曼岛，开始往北方大陆搜。和马官方一致，但和美媒不一致。
回头他们说是“椰神”给的VISION。。。。
我个人觉得cnn就是一个草根电视台，没啥内部报料，今天这么说，明天那么说，就他能代表美国媒体都要笑掉牙了
我觉得劫机比“误炸”大使馆性质恶劣多了
首先美国自己也深受911之痛
再自己整一个劫机更会有人认为911就是政府搞的了
二是这架飞机上虽然中国人最多
但是其他国家的人也不少啊
这劫机万一败漏
国际媒体得拿板砖把美国拍死
如果为了灭口情报人员，在机场劫持甚至开枪都比这个好收场
如果为了搞乱中国，扶植分裂势力或者让日本，台湾，菲猴上都成
对。劫机涉及的环节多了。万一被抓住任何一个环节漏洞爆出来。相对于他所得到的好处来说，后果是美国来说不能承受的。除非飞机上是美国核安全密码之类的顶级绝密。
看来很有可能冤枉了那个机长，这个副机师劫机的可能性陡增。
前几天就有人分析说飞机失去联系的时间正好是可以自动平稳飞行，机长可以歇口气让副机师驾驶的时间段。
没想到那么喜欢泡洋妞的人居然这么不热爱生命。
俩人都参与也不矛盾，副机长哪有着技术，且机长一家都无影无踪了
越来越小说了，建议阅读紫金陈谋官系列第四部，有详细的闷翻一车人的攻略。估计放大一下，一飞机的人也不在话下。说实话我太难以相信这个在实际生活中会发生。
那就有可能今天早上开，明天下午开，后天晚上开。
你们那些心怀鬼胎要闯三哥领空的人是不会得逞的！
机长家人提前搬走是误传，机长老婆在警方搜索之后还回家拿过东西
俩人不太可能是协同，因为共同执行这个航班不是他们自己要求的，是公司常规安排，他们不可能提前太多知道
这个很难说啊，这种通讯系统的原理是什么我们不知道啊，
就象网络传送数据，送出去的数据是不是给对方收到要等下一个handshake回来才能确定。简单说就是, the receiver sent back a message to the sender and confirm it received the last message, I am ready for the next one.
所以光看时间不能说明问题，只能说明通讯系统是在那个时间段附近关闭的
以前恐怖分子不知道，估计有威慑力，这下倒好，大家全知道了。
现在是住在另外一个住宅，昨天东方新闻的前方记者纠正了出事前一天妻子女儿搬去另外一个住处的说法，说那个说法不正确，没有提前搬走
机长家人也没逃跑，人家只是换了一个自己的房子住而已。
塔利班躺枪了 好无辜的感觉
这则消息好搞笑。
re. 感觉很多东西就是lost in translation。之前有 static 给翻译成静电噪音了，然后就有人出来说明这个空中静电的产生和坠机的关系。还有马来的原话肯定不是飞机上没有打斗的痕迹，现在公布的消息肯定都是很多脑子一起掂量了再掂量之后才公布的，脑子再不好使也不会这么说吧。
我忍不住笑了
so what does static mean in chinese?
不是卫星去PING飞机，而是飞机PING卫星(向卫星发出连线请求)，我想每个发动机对应一个固定的卫星。
但因为他没买该服务，卫星不予回应。类似于你给别人打电话对方没接，但是对方能通过log知道你何时打过电话，打过几次等等。
