The pictures, understood to have been captured by US intelligence surveillance shared with Australia, were taken on March 16 but did not reach the Australian Maritime Safety Authority until yesterday morning.
我查了资料 CNN确实说了是根据ping信号数据得出来的 视频里和报道里都有。。
CNN报道里
The analysis used radar data and satellite pings to calculate that the plane diverted to the west, across the Malayan peninsula, and then either flew in a northwest direction toward the Bay of Bengal or southwest into the Indian Ocean.
The theory builds on earlier revelations by U.S. officials that an automated reporting system on the airliner was pinging satellites for up to five hours after its last reported contact with air traffic controllers.
南北两个走廊确实是根据卫星ping信号数据而得来的，并没有说是引擎信号
Rolls-Royce engines kept transmitting information for at least four hours after the last known contact with the plane. Later in the day, the Journal issued a correction — saying that the signals some investigators say were being sent came from "the plane's satellite-communications link," not from the Rolls-Royce engines.
你说的引擎数据是一开始后来报道说并不是来源于引擎 而是卫星连接，推出弧线的和最初报道的引擎信号没关系
不止是我也有人疑问，不过好像很少人关注这个问题

One ping per hour for 7 hours = 7 pings, 7 circles. Why don't they show the 7 arcs? You could probably see where it was headed, knowing the approximate speed.
Manuel WeberA. Kordesch Having only the last arc, if in fact this arc truely represents that the aircraft in question was somewhere along that arc, and for whatever reason not having the other (ping) arcs, we can be sure this is the hardest evidence we have concerning the position of the aircraft at that 8 oclock in the morning ping.
WE NEED THE OTHER PING ARCS....PERIOD.
WE NEED THE HOURLY PINGS. They may tell us nothing, or they may prove to be a key to the mystery.
Ocean expert Dr Robin Beaman from James Cook University said debris could have been carried hundreds of kilometres since the satellite images were captured on March 16.
“The currents are drifting at one or two nautical miles per hour so it certainly makes sense that it could have drifted several hundred miles by now,” he said.
“There’d be parts of the plane that could float for some time but certainly not indefinitely. “Eventually parts like that will become waterlogged and sink to the sea floor so it’s time critical,” he said. 本帖最后由 50912cmea 于 21-3-2014 04:26 PM 编辑
The area in the southern Indian Ocean is so remote is takes the RAAF P3 Orion four hours to fly there and four hours back, and leaves them only about two hours to search.
