SEPANG - The last words - "All right, good night" - spoken from the cockpit of Malaysia Airlines light MH370 was uttered by co-pilot Fariq Abdul Hamid.
Initial investigations indicate it was the co-pilot who spoke the last time any communication was recorded on tape.
"The recording is now with air traffic control," MAS chief executive officer Ahmad Jauhari Yahya said at a news briefing yesterday.
Captain Zaharie Ahmad Shah and his first officer Fariq have become a primary focus of the investigation into the fate of Flight 370, with one of the key questions being who was controlling the aircraft when the communications systems were disabled.
"The last Aircraft Communications Addressing and Reporting System (ACARS) transmission was at 1.07am. We do not know when the ACARS was switched off after that.
"It was supposed to transmit 30 minutes from there, but the transmission did not go through and the very last transmission was at 1.07am," he added.
Ahmad Jauhari confirmed that the last communication from the cockpit was recorded at 1.19am.
But he refused to confirm that the ACARS was disabled before the final message, which indicates that one of the pilots or someone aboard the aircraft was deliberately misleading the control tower while switching off the ACARS.
Department of Civil Aviation director-general Datuk Azharuddin Abdul Rahman said there was no indication when the ACARS was turned off at that point of flight.
"We have no indication at the control centre to say that the ACARS was switched off.
"It was only revealed that the information was not downloaded by the ACARS to the centre at MAS," he said.
Meanwhile, Azharuddin said the aircraft's Emergency Location Transmitting System (ELTS) was working as it was one of the major items to be checked before a flight.
"Every emergency item like the ELTS will always be armed and it will trigger when the aircraft touches water or if it is in a crash," he added.
Ahmad Jauhari also said checks were being made whether there was contact from any of the passengers on their cellphones since the aircraft went missing.
"We had not had any evidence from any telco companies of any number that had tried to contact (the ground).
"But, we are still checking as there are millions of records that we need to check. It is being done as part of the investigations," he added.
Acting Transport Minister Datuk Seri Hishammuddin Hussein could not immediately confirm whether the investigators had spoken with the pilot who had reportedly made contact with the aircraft shortly before it went missing.
"Not that I know of," Hishammuddin said.
The unnamed pilot claimed that he was on his Japan-bound plane which was in Vietnamese airspace when officials asked him to relay to MH370 to establish its position.
The person was said to have succeeded at about 1.30am local time, but all he heard was interference, static and mumbling.
Hishammuddin confirmed that the investigators were looking into pilot suicide as among the many factors in the probe, but declined to elaborate.
