(NEWSER) – Thailand is offering what CNN calls "the second radar evidence" that the missing Malaysia Airlines flight took an altered path toward the Strait of Malacca. All looked normal on Thailand's military radar until 1:22am, when Flight 370 vanished. Within six minutes, an unknown aircraft was spotted moving in the opposite direction, a Thai air force official tells CNN, indicating the flight may have taken a sharp turn to the west. "The unknown aircraft's signal was sending out intermittently, on and off, and on and off," says the official. Due to radar limitations, the signal was later lost. The Malaysian Air Force earlier stated its radar tracked the plane over the Strait of Malacca; the BBC notes the Thai military earlier said it picked up no sign of the plane.
- As for what happened next, experts tell CNN that even a jet as big as the Boeing 777 could keep itself hidden. "It certainly is possible to fly through the mountains in that part of the world and not be visible on radar," says a security consultant. An "experienced pilot … can easily determine, where are the radar blind spots?"
