re: Official Thread: Missing Malaysia Airlines Flight 370

Radar signals recorded by the Malaysian military appear to show the missing airliner climbing to 45,000 feet, above the approved altitude limit for a Boeing 777-200, soon after it disappeared from civilian radar and made a sharp turn to the west, according to a preliminary assessment by a person familiar with the data.

The radar track, which the Malaysian government has not released but says it has provided to the United States and China, then shows the plane descending unevenly to an altitude of 23,000 feet, below normal cruising levels, as it approached the densely populated island of Penang, one of the country’s largest. There, the plane turned from a southwest-bound course, climbed to a higher altitude and flew northwest over the Strait of Malacca toward the Indian Ocean.

Investigators have also examined data transmitted from the plane’s Rolls-Royce engines that shows it descending 40,000 feet in the space of a minute, according to a senior American official briefed on the investigation. But investigators do not believe the readings are accurate because the aircraft would likely have taken longer to fall such a distance.

“A lot of stock cannot be put in the altitude data” sent from the engines, one official said. “A lot of this doesn’t make sense.”
