由于机舱面积极为狭窄，只有极少数摄影记者可以随军参与搜救过程。11日，记者专门采访了参与跟机的新华社记者，他形容说：“海面太过辽阔，渔船用于存放鱼虾的容器很容易被误认为是白色物体，肉眼难以分辨。”
“有一次，飞行员突然大叫，疑似发现了可疑物。机身也快速倾斜并下降，马达声伴随着机舱门开启变得分外嘈杂。经过约5分钟的超低空飞行，确认是虚惊一场才离开。”亲历的记者描述说。外嘈杂。经过约5分钟的超低空飞行，确认是虚惊一场才离开。”亲历的记者描述说。
参与搜救的飞机中，包括目前越南最先进的巡查机CASA。该机可以连续5个小时执行任务，装备海上搜寻系统，专门用于在边界地区搜寻漂浮在海面的油渍和森林防火等。CASA可以下降到海面以上100米，装备有“神眼”摄像器材，观察距离为3000-5000米。
马来西亚：督巴里直击
3月11日中午，21世纪经济报道特派马来西亚记者来到马来西亚东北部的小镇督巴里，这里是马来西亚的一个搜救中心。在督巴里海事执法机构的港口，几艘巡逻艇停靠在这个码头，几名工作人员在艇上聊天。21世纪经济报道试图接近他们，但是被执法人员阻止。
一位来自吉隆坡的马来西亚英文媒体记者说，越南方面总喜欢即时发布信息，但是马来西亚不是这样的，“要核实了才向公众发布。”
在督巴里海事执法机构码头附近，21世纪经济报道记者遇到了一位来自吉隆坡的华人志愿者黄先生，他自己驾车从吉隆坡来到督巴里，在询问了海事执法机构，并且寻找了附近数个渔民码头之后，没有找到任何前往失联客机失事海域的船只。
21世纪经济报道还随同黄先生一同前往十多公里外的kuala besut小镇打听一些情况并寻找出海的渔船，但未能找到。
督巴里属于马来西亚吉兰丹州，距离州首府哥打巴鲁80公里左右。3月11日傍晚，在哥打巴鲁，吉兰丹警察总署总警长拿督查拉鲁丁召开了记者会。记者会上，查拉鲁丁回应了前一天关于有目击证人称在飞机失联当晚在相关海域看到飞机低空飞机然后爆炸的消息。查拉鲁丁称，警方的初步调查报告已出，交给了民航部门进行深度调查。
中国：调整优化搜救方案
3月11日下午，交通运输部马航失联客机应急反应领导小组副组长、副部长何建中在交通运输部应急反应领导小组第6次会议上要求，进一步调整优化搜救方案，适当扩大搜寻范围，并协调中国籍过往商船积极参与搜救。
目前，我方已有“海巡31” 轮、“南海救101”轮、“南海救115”轮、海军“528”舰、海军“999”舰、海军“171”舰、“中国海警3411”轮共7艘船艇在现场展开搜寻。后续海军998舰预计于12日8时抵达。
截至11日18时，现场船艇、飞机及过往商船累计搜救范围约6000平方公里，未发现可疑漂浮物与海底可疑点。
从中国海上搜救中心获悉，美国、马来西亚、越南、新加坡、泰国、印尼、澳大利亚等国家及台湾地区派出10架飞机、33艘舰船参与搜救任务，另有11艘舰船正赶往搜救区，均无实质性发现。
据中国海上搜救中心总值班室副主任卓立介绍，由于目前掌握的马航失联客机相关信息极为有限，失联海域范围又十分广阔，这给搜救工作带来了不小难度。 Mystery Malaysia flight may have lost signal, gone hundreds of miles off course
(CNN) -- It was 1:30 a.m. when Malaysia Airlines Flight 370 lost all communications, including important transponder signals that send data on altitude, direction and speed. Still, it showed up on radar for about 1 hour, 10 minutes longer -- until it vanished, having apparently moved away from its intended destination, hundreds of miles off course.
Those details -- told to CNN by a senior Malaysian air force official, who declined to be named because he is not authorized to speak to the media -- seemingly shed more light on what happened to the aircraft that mysteriously went missing early Saturday.
But if these assertions are true -- and other reports, citing a different Malaysian official, cast doubt on them -- many big questions remain. Why were the communications lost? Why was the Boeing 777 going the direction it was? And where did it end up?
"Something happened to that airplane, that was obviously out of the norm, that caused it to depart from its normal flight path," said Mark Weiss, a former 777 pilot now with the Washington-based Spectrum Group consulting firm. "... It's difficult not to speculate."
Peter Goelz, former managing director of the National Transportation Safety Board, thinks all this information -- if correct -- ominously suggests that someone purposefully cut off the transponder and steered the plane from its intended destination.
"This kind of deviation in course is simply inexplicable," said Goelz.
Other experts aren't convinced that there were bad actors -- be they hijackers or an ill-intentioned crew member. They say there could have been some sort of sudden catastrophic electronic failure or more that spurred the crew to try to turn around, with no luck.
"Perhaps there was a power problem," said veteran pilot Kit Darby, former president of Aviation Information Resources, adding that backup power systems would only last about an hour. "(It is) natural for the pilot, in my view, to return to where he knows the airports."
Still, while they have theories, even those who have piloted massive commercial airliners like this one admit that they can't conclude anything until the plane is found. For now, the massive multinational search has yielded no breakthrough -- which has only added to the heartache for the friends and family of the 239 passengers and crew on board.
The Malaysian air force official's revelations may provide more direction, though clarity and closure are still elusive.
"There are still as many possibilities out there, maybe more, now that we know about the transponders being off and the length of time that plane flew in the air without them," said CNN law enforcement analyst Tom Fuentes. "It still leaves mechanical, terrorism (and) other issues as much in the air as they were before."
Intentional or catastrophic mechanical failure?
According to the Malaysian air force official, the plane's transponder apparently stopped working at about the time flight controllers lost contact with it, near the coast of Vietnam.
The air force eventually and totally lost track of the plane over Pulau Perak, a tiny island in the Strait of Malacca -- many hundreds of miles from the usual flight path for aircraft traveling between Kuala Lumpur and Beijing, the official said.
If the data cited by the source is correct, the aircraft was flying away from Beijing and on the opposite side of the Malay Peninsula from its scheduled route.加拿大华人网 http://www.sinoca.com/
