Final words The phrase "all right, good night" became famous around the world when it was revealed as the final official communication from the pilots of MH370. On Monday, however, the Malaysian civil aviation authority confirmed the last words of one of the pilots before the aircraft dropped off the radar was in fact, “Good night, Malaysian three seven zero”. "We would like to confirm that the last conversation in the transcript between the air traffic controller and the cockpit is at 0119 (Malaysian Time) and is "Good night Malaysian three seven zero," the Department of Civil Aviation said in a statement.

Malaysia officials initially said that the co-pilot, Fariq Abdul Hamid, gave the sign-off. Shifting zones: searching the Indian Ocean from a Japan Coast Guard Gulfstream V aircraft.

3. When did communication disappear? The timing of the pilots' final message - in relation to the communications system being switched off and the plane turning around - is particularly crucial in trying to establish if one or both of them were involved in the plane’s disappearance. Officials initially said that the sign-off came after one of the jetliner's data communications systems - the Aircraft and Communications Addressing and Reporting System, or ACARS - had been switched off at 1.07am on March 8. About 14 minutes later, the transponder, which identifies the plane to commercial radar systems, was also shut down. If true, this could have indicated the pilots were alert and in control of the plane and had purposefully switched off the communications system. It subsequently generated headlines around the world. However, Malaysia Airlines CEO Ahmad Jauhari Yahya later amended the information, saying authorities could only establish that the final ACARS transmission came at 1.07am.

"We don’t know when the ACARS system was switched off," he said. Instead, they could only provide a window of between 1.07am and 1.37am. With the final cockpit communication at 1.19am, this failed to clarify which came first. 4. Dead or alive? Last week, Malaysian Prime Minister Najib Razak all hope was lost for the 239 passengers on board the MH370. The families of the passengers received a text message from Malaysia Airlines declaring it was “beyond reasonable doubt” that the aircraft had crashed into the Indian Ocean. It was a move backed by Australian Prime Minister Tony Abbott and aviation experts.

However the following Saturday, the Malaysian acting Transport Minister, Hishammuddin Hussein, went on to tell relatives who questioned the announcement that there was still a remote chance survivors could be found. 5. Which way did it go? Conflicting reports emerged days after the Boeing 777 disappeared about when air traffic controllers lost contact with the aircraft and where the most likely search area should be. Authorities had repeatedly said that Subang air traffic control, which covers Kuala Lumpur airport, lost contact with the aircraft at 1.30am on March 8, when the plane was over the Gulf of Thailand. But four days into the investigation, the country’s air force chief, General Rodzali Daud, was quoted in a Malaysian newspaper saying the plane changed course sharply and headed west out over the Strait of Malacca - the opposite area in which investigators had been searching.

General Daud subsequently released a statement denying the newspaper report. The search later turned to the Indian Ocean - but after three days, the area was moved about 1000km northeast of its previous position. The Australian Maritime Safety Authority (AMSA) reported the move was based on new information from the ongoing analysis of radar data as the aircraft travelled from the South China Sea and the Strait of Malacca. 6. Passengers who failed to board the plane Khalid Abu Bakar, the inspector-general of the Malaysian police, said previous reports by Malaysian officials that five passengers had failed to board the flight and that their baggage had been removed were false. “Everybody that booked the flight boarded the plane,” he said.

But Malaysia Airlines later issued a clarification, saying that there were four passengers who booked tickets on the flight but failed to check in at the airport or check any bags for the flight. 7. How many passengers were travelling on stolen passports? Authorities were said to be investigating the possibility that up to four people were travelling on stolen passports on flight MH 370, but this was later revised to only two. 8. What nationality were they? Interpol eventually identified Pouria Nour Mohammad Mehrdad, 19, and Delavar Seyedmohammaderza, 29. They were Iranians believed to be seeking asylum in Europe.

But before they were identified, the Malaysian Home Minister, Ahmad Zahid Hamidi, described the pair as being Asian in appearance. He was then contradicted by the civil aviation chief, Azharuddin Abdul Rahman, who said they were of "non-Asian" appearance, in a bizarre press conference which made references to the Italian footballer Mario Balotelli.
