The Japanese pilot who made contact with the plane told Malaysian media outlets his plane, which was bound for Narita, Japan, was in Vietnamese airspace when he was asked to contact the pilot flying the missing plane.

In using his plane’s emergency frequency, he was asked to try and establish its position after authorities failed to make contact.

“We managed to establish contact with MH370 just after 1.30am and asked them if they have transferred into Vietnamese airspace,” he told the New Straits Times.

“The voice on the other side could have been either Captain Zaharie or Fariq, but I was sure it was the co-pilot.

“There were a lot of interference... static... but I heard mumbling from the other end.

“That was the last time we heard from them, as we lost the connection,” he said.”

He said those on the same frequency at the time would have heard him, including vessels on the waters below.
