Thailand has revealed radar evidence that supports the hypothesis that missing Malaysia Airlines flight MH370 did turn around as it flew over Pulau Perak in the Strait of Malacca on Tuesday (March 18).

The new information came 10 days after Malaysia Airlines flight MH370 went missing on March 8. According to CNN, the Thai military was receiving normal flight path and communication data from flight MH370 on its planned March 8 route from Kuala Lumpur to Beijing until approximately 1:22 a.m., when it disappeared from its radar screens. Six minutes later, the Thai military detected an unknown signal, possibly MH370, heading the opposite direction.

Thailand's military officials said they didn't share the information with Malaysia earlier because it wasn't specifically asked to do so, the National Post reported.

This is the second batch of data that supports the hypothesis that MH370 did turn around as it flew over Pulau Perak in the Strait of Malacca. However, although the data further confirms the flight did change direction at a known location, its destination remains a mystery.
