New Information Narrows Missing Airliner’s Flight Path By Jeff Wise In a case that is swirling with uncertainties, a few pieces of evidence have stood apart for seeming reliability. Among them was the revelation last Saturday by Malaysia Prime Minister Najib Razak that his country’s investigators, in collaboration with U.S. authorities, had analyzed an electronic ping that MH370 had broadcast to the Inmarsat satellite at 8:11 a.m. on the morning of the disappearance. Based on this data, the investigators had determined that at that moment MH370 must have been somewhere along one of two broad arcs: one which passed through Central Asia, and the other of which covered a swath of largely empty Indian Ocean, far to the south.
The revelation left a burning question unresolved: what about the six earlier pings, which had been exchanged between the aircraft and the satellite about once per hour? Could any position data be deduced from them?
Today, Inmarsat revealed some crucial information. “The ping timings got longer,” Inmarsat spokesman Chris McLaughlin stated via email. That is to say, at each stage of its journey, the aircraft got progressively farther away from the geostationary satellite’s position, located over a spot on the equator south of Pakistan, and never changed its heading in a direction that took it closer—at least for very long.
The last known position of MH370 before it disappeared from Malaysia military radar was over the Andaman Sea, between the Malay Peninsula and the Andaman Islands. The time was about 2:15 a.m., and coincided with the first of the seven Inmarsat pings.
In order for its flight to have taken it ever farther from Inmarsat, MH370 would have had to have traveled within either of two narrow bands. One pointed north, toward India, Bangladesh, and Burma. The other pointed south, across Indonesian airspace and then across the Indian Ocean west of Australia.
The narrower range of possible flight paths reduces the number of plausible scenarios and suggests avenues of investigation. For instance, some have speculated that whoever was at the controls might have flown out over the open ocean, turned left and headed toward the southern arc in order to avoid passing through any areas of military radar coverage. That route is no longer possible. If the plane did travel south, its path should be detectable on stored Indonesian military radar returns.
if the plane was on the Southern arc at the last ping, then the plane had to fly directly over Indonesia, which *should* (but might not, who knows?) have detected it on radar. It could not have diverted around Indonesia to the West over the ocean to avoid radar, since that 90-minute diversion would have brought one hourly ping *closer* to the INMARSAT satellite.
Malaysian Airline System Bhd. (MAS) and Boeing Co. records on Flight 370’s maintenance and crew are being sought by a law firm representing the father of one of the missing flight’s passengers, the opening salvo in what may end up being a barrage of litigation over the plane’s disappearance. The jet carrying 239 people vanished March 8 from radar after taking off from Kuala Lumpur for Beijing. Malaysia’s government said March 24 the plane probably crashed in the South Indian Ocean, southwest of Perth, Australia, with no survivors, citing satellite data. The request for information by Chicago-based Ribbeck Law Chartered on behalf of Januari Siregar is a potential prelude to the filing of a lawsuit. Siregar’s son, Firman Chandra Siregar, was a passenger on Flight 370, according to the firm. In a filing yesterday in Illinois state court in Chicago, Siregar seeks 26 different kinds of information, including data on possible defects in the missing Boeing-built 777-200 ER or its component parts, the airline’s training of its crew and information about its cargo. Siregar seeks “possible design and manufacturing defects that may have contributed to the disaster,” Ribbeck partner Monica Kelly said yesterday in a statement. The law firm said the petition seeking evidence is the same request it used when it began legal proceedings against Asiana Airlines Inc. after a July 6 crash of one of that carrier’s planes landing at San Francisco International Airport, also a 777-200, killed three people and injured 181.
"We have to clear every little thing," the inspector general of Malaysian police, Khalid Abu Bakar, told reporters after a speech at a police academy in Kuala Lumpur. "You cannot hurry us in whatever we are doing."
The people who prepared the food for the flight are being scrutinized, as are the people who packed the cargo and the people who were to have received the cargo, he said, adding, "Everything from beginning to end."
Investigators have cleared all 227 passengers of any role in hijacking or sabotage and of having personal or psychological issues that might have played a role in the plane's disappearance, he said.
And a senior Malaysian government official told CNN last week that authorities have found nothing about either of the pilots to suggest a possible motive.

【搜救进展】[“雪龙”号前进至距搜寻目标1000海里]21日晚“雪龙”号从澳大利亚弗里曼特尔码头出发后，昼夜兼程一路向西南方向航行，直奔搜寻目标—位于南纬43度28分、东经91度45分的“1号点”。22日一整天，南印度洋天气阴沉，海面上浪高3至4米，风力八级，阵风九级，“雪龙”号最大摇摆度达到15度，涌浪甚至打到了驾驶台的玻璃上。 预计“雪龙”号还需航行70个小时抵达目标位置。目前，考察队已将船上科考队员进行了分组培训，并在船头、船中和船尾设立三个瞭望点，安排人员24小时值班，沿途上岗瞭望。目前尚未在海面上发现漂浮物。 “雪龙”号搜寻工作总指挥刘顺林说，在一路航行过程中，我们将不放过任何一个搜寻的机会。(新华网)
提醒雪龙：风浪这么大18日的卫星位置早飘走了。
机长在起飞之前打了两分种电话，用的是pay to go 电话，电话卡是用假身份证购买。
机长可疑。
CNN分析员说失联飞机转弯极速下降有可能是因为飞机发生了紧急故障，同时失去了通信，如果是这样的话，机长忙于救急，用autopilot飞行。。。
这样的话，机长两个是英雄。

显然在绕开马来西亚陆地，为什么？
TNND，过那么久才纠正。
马来猪什么时候才能说实话！！
1）飞机没有机械故障，转弯是人为行为，
2）那么通信故障也是人为的，
3）更严重的可能，飞机最后飞哪里了？

梦见一群人（不知道什么时候）在一个岛上进行什么地质勘察，或者是探险什么活动，大家一起在挖东西，然后一个女的突然挖到尸体，很完整的被掩埋在土里，她大叫一声，结果更多人来挖，挖到更多尸体，结果发现是370的失事飞机失事点。
做梦做得迷迷糊糊，只记得跟生化武器有关，那么多人死了是因为生化武器之类的东西。
仅当大家一笑。
调查了所有的人，均无嫌疑。

解放日报报道称，信号是昨日“海巡01”轮黑匣子搜寻小艇上的人员搜听到的，艇上同时有三人证实搜听到疑似信号，但由于信号搜听到时非常突然，当时来不及将信号录制下来。
报道称，今日16时30分左右，侦听到1分半左右的信号，目前此信号与MH370的关联性正在确认中。
目前正在全力确认脉冲信号与失联客机的关联性，中方两艘军舰也已赶到相关海域。
调查人员此前断定，载有239人的MH370客机在3月8日凌晨从民用雷达上消失数小时后耗尽了航油，坠落在距最近机场上千公里的海域。
飞机黑匣子或记录了飞机出事原因的关键线索，其信号发射器可连续工作约30天，而最快或在本周末耗尽电量。
据悉，波音777客机上的黑匣子带有水下信标(ULB)，飞机一旦入水，ULB就会被激活，持续的发出37.5kHz的脉冲信号，这种信号可以被声呐和声学定位仪探测到，ULB可以持续发出30天左右的信号。
