剧情逆转，黑匣子在海寻搜索处？

专栏昨日刊文说，美国《新乡时报》4月14日的报道称，使用简陋搜索设备的中国海巡01轮宣布自己在印度洋侦测到了疑似由马航失联班机发出的信号，但英国配备精密侦测设备的船只前往复查后，却未能侦测到任何信号。报道认为，中国的这一举动可能对澳大利亚同时进行的搜寻工作构成了干扰，后者同样配备高科技侦测设备的“海盾”轮发现了四个疑似由马航空失联客机发出的信号。

《新乡时报》的这篇报道说，4月5日，明显是在搜索行动协调员指定的区域之外进行搜寻的中国海巡01轮宣布，自己在印度洋侦测到了疑似由马航失联班机发出的信号。
那么，这个中国在“指定区域之外”发现疑似信号的地方具体位于何处呢？据人民网4月7日的报道说，当日，澳大利亚联合协调中心总负责人休斯顿召开新闻发布会说，海巡01轮和“海盾”轮两船的搜索区域均在失联飞机与卫星“握手”的地点弧线上，海巡01轮5日探测到马航失联飞机疑似信号的位置位于澳大利亚珀斯西北约1550公里处，而“海盾”轮6日探测到疑似信号的区域则位于珀斯西北约1680公里处，两处相距约555公里。

路透社4月7日的报道也说，调查人员对卫星数据进行分析后认为，马航失联飞机坠落于珀斯西北约1680公里的地方，澳大利亚“海盾”轮正是在这个地方侦测到了疑似由这架失联飞机黑匣子发出的信号。

此后的媒体报道显示，澳大利亚“海盾”轮在4月6日后又连续几次侦测到疑似信号，而中国海巡01轮则再无收获。鉴于中国和澳大利亚所发现信号的位置相距有555公里，中国使用的搜索设备简陋，澳方使用的设备先进，且澳大利亚侦测到的疑似信号多且日期跨度长，外界似乎不难认定，中国海巡01轮的发现更有可能不靠谱。

但路透社4月14日却报道说，搜寻人员目前相信，马航那架失联客机的残骸位于澳大利亚珀斯西北约1550公里处，他们正以“海盾”轮探测到的四个马航失联客机疑似信号为基础进一步推进搜寻工作。

这就有点奇怪了，经过一周多的搜寻后，调查人员“锁定”的马航失联班机残骸位置不是澳大利亚方面最初侦测到疑似信号的珀斯西北约1680公里处，而恰恰是中国海巡01轮称自己探测到疑似信号的地方：珀斯西北约1550公里处。

这如何解释呢？如果中国用于此次马航失联客机搜索工作的装备真像一些媒体说的那样简陋的话，那么唯一能解释这一现象的理由或许只能是，中国不是歪打正着就是有老天爷帮忙。

(Reuters) - The head of the Australian agency supervising the search for a missing Malaysia Airlines plane said on Monday that an autonomous underwater vehicle would soon be deployed, moving the search underwater after nearly six weeks of fruitless searching.

Malaysia Airlines Flight MH370 disappeared soon after taking off on March 8 from Kuala Lumpur bound for Beijing with 227 passengers and 12 crew on board.

Searchers are confident they know the approximate position of wreckage of the Boeing 777, some 1,550 km (963 miles) northwest of Perth, and are moving ahead on the basis of four acoustic signals they believe are from its black box recorders.

"Despite the lack of further detections, the four signals previously acquired taken together constitute the most promising lead we have in the search for MH370," Angus Houston, the Australian search chief, told reporters in Perth.

"The experts have therefore determined that the Australian Ocean Shield will cease searching with a towed pinger locator later today and deploy the autonomous underwater vehicle, 'Bluefin-21', as soon as possible," he said, referring to the U.S. Navy device designed to detect the tell-tale "pings".
The batteries in the plane's black box are now two weeks past their 30-day expected life and searchers will be relying on sonar and cameras on the Bluefiun-21 to detect the box.

Houston added that although an oil slick was located in the search area on Sunday evening, he was pessimistic about the likelihood of finding any of the floating debris.

"The chances of any floating material being recovered have greatly diminished and it will be appropriate to confer with Australia's partners to decide the way ahead later this week," Houston said.
