Thailand’s Air Force says it was tracking Malaysia Airlines Flight 370, lost it, then picked up another aircraft flying in a bizarre way toward the west.

At 1:22 a.m., military radar picked up the plane, which was reportedly still on course three minutes after the co-pilot said goodnight.

At 1:28 a.m., Thai radar picked up an unidentified plane that began following a twisted path toward Malaysia. The signal was infrequent, and authorities don’t know or won’t say when the plane was last detected. Authorities say they didn’t pay attention to it at the time because the plane did not pose a threat.

This timing would jive with Malaysian military radar, which spotted the plane at 2:14 a.m. going into the Strait of Malacca.

The Malaysian military never confirmed reports of the plane zig-zagging between different waypoints that would have put the plane on course to go past China, Pakistan, Iran and India. Those countries all have sophisticated radar that never detected the missing jetliner.

China said it has not found any sign that the plane entered Chinese territorial airspace.
