Malaysia Airlines Flight 370 did not dramatically climb to 45,000 and then dive below 23,000 feet after completing a U-turn before it disappeared. That is the conclusion of investigators looking into the disappearance, who say Malaysian radars hadn’t been calibrated precisely enough to draw any conclusions about altitude. “The primary radar data pertaining to altitude is regarded as unreliable,” said Angus Houston, the retired head of the Australian military who is in charge of the search. Instead—as The Daily Beast’s own Clive Irving wrote several months ago—the plane was probably not seriously damaged and remained in controlled flight until it ran out of fuel over the Indian Ocean. So no flying into a cave in Pakistan, either.
