| The search for missing Malaysia Airlines flight MH370 was focused on the Bay of Bengal late on Friday after satellite data showed that the aircraft could have flown on for hours and US officials confirmed they had directed surveillance aircraft to patrol the area for debris. | The search for missing Malaysia Airlines flight MH370 was focused on the Bay of Bengal late on Friday after satellite data showed that the aircraft could have flown on for hours and US officials confirmed they had directed surveillance aircraft to patrol the area for debris. |
| There were reports that Malaysian military radar indicated the plane made at least two distinct changes of course after apparently turning back from its route towards Beijing. US officials indicated that they believed the plane had crashed in the Indian Ocean and had ordered an aerial search of the area beginning on Saturday. Malaysian officials said they were investigating the possibility that the plane's communications systems had been deliberately shut down. | There were reports that Malaysian military radar indicated the plane made at least two distinct changes of course after apparently turning back from its route towards Beijing.

| A week after the the aircraft vanished, there was still no trace of it, despite a huge international search involving 13 countries. The strongest indication that the plane had flown on for hours came from Inmarsat, a British-based provider of satellite equipment, which said it had continued to receive "pings" from the aircraft well after its last contact with air traffic control. | A week after the the aircraft vanished, there was still no trace of it, despite a huge international search involving 13 countries. The strongest indication that the plane had flown on for hours came from Inmarsat, a British-based provider of satellite equipment, which said it had continued to receive "pings" from the aircraft well after its last contact with air traffic control. |
| There were competing theories about why and how the plane had changed course. The three main possibilities under consideration, according to a variety of US officials quoted by a range of media outlets, were air piracy, hijacking or pilot suicide. The initial working explanation for the plane's disappearance – that it had suffered a catastrophic mechanical failure on its route from Kuala Lumpur to Beijing over the Gulf of Thailand – appeared to be fading from prominence. | |
| The US navy confirmed to the Guardian that it had deployed a P-8A Poseidon surveillance aircraft to scour the Bay of Bengal for debris on Saturday. A spokesman said it would search a "much larger area .... the southern portion of the Bay of Bengal and the northern portion of the Indian Ocean". | |
| The USS Kidd, a guided missile destroyer that has been searching the Strait of Malacca, was moving further west, preparing to search the Andaman Sea and the Bay of Bengal. A P-3C Orion completed an aerial search of the north-west section of the Strait of Malacca "where it flew approximately 1,000 miles west with nothing significant to report", according to the US embassy in Kuala Lumpur. | |
| In a further indication that the plane was under piloted control, the New York Times reported that Malaysian military radar data showed the jet climbed to 45,000ft, above the approved altitude limit for a Boeing 777-200, soon after its last known position, after making a turn to the west. It said there were indications that MH370 descended to 23,000ft on the approach to Penang, one of Malaysia's largest and most densely populated islands. Then came another turn, this time north-west on a trajectory that took it over the Strait of Malacca and out towards the Indian Ocean. | In a further indication that the plane was under piloted control, the New York Times reported that Malaysian military radar data showed the jet climbed to 45,000ft, above the approved altitude limit for a Boeing 777-200, soon after its last known position, after making a turn to the west.

| The Inmarsat signals, described as a series of hourly pings to a satellite, also indicated the plane had continued to fly beyond its last known point of contact. The Inmarsat signals do not transmit location but can indicate a position and distance relative to the satellite, which could give a guide to a rough direction of travel over several hours. David Coiley, vice-president of aviation at Inmarsat, told the Guardian that the receipt of such pings indicate "that the satellite communications are functioning". | The Inmarsat signals, described as a series of hourly pings to a satellite, also indicated the plane had continued to fly beyond its last known point of contact.

| The Wall Street Journal quoted US officials who said these signals persisted for another four to five hours. Reuters said the data led US officials to believe the plane crashed in the Indian Ocean. | |
| The last known position of MH370 was at 1.21am on Saturday 8 March, at 35,000ft roughly 90 miles off the east coast of Malaysia as the plane, with 239 people on board, made its way towards Vietnam en route to Beijing. | |
| According to two US officials who spoke to ABC News, the Boeing 777's data reporting system was shut down at 1.07am, while the transponder – which sends back information to civilian radar regarding performance, location and altitude – was turned off at 1.21am. That led investigators to believe the systems had been switched off on purpose. | |
| Meanwhile the White House refused to comment on suggestions that US officials believe there may have been "an act of piracy". Jay Carney, the White House spokesman, said: "This is a difficult and unusual situation and we are working hard in close collaboration with the Malaysian government to investigate a number of possible scenarios for what happened to the flight. | Meanwhile the White House refused to comment on suggestions that US officials believe there may have been "an act of piracy".

| Sources told Reuters that the flight path of an unidentified aircraft, believed by investigators to have been the MH370 jet, followed a route with specific navigational waypoints, west towards the Andaman Islands after it last made contact with air traffic control. | Sources told Reuters that the flight path of an unidentified aircraft, believed by investigators to have been the MH370 jet, followed a route with specific navigational waypoints, west towards the Andaman Islands after it last made contact with air traffic control. |
| If the aircraft picked up on the military radar is the missing jet, the data suggests it veered dramatically and deliberately westwards, heading north-east of Indonesia's Aceh province towards a navigational waypoint used for carriers headed towards the Middle East. | If the aircraft picked up on the military radar is the missing jet, the data suggests it veered dramatically and deliberately westwards, heading north-east of Indonesia's Aceh province towards a navigational waypoint used for carriers headed towards the Middle East. |
| Malaysian military officials have previously confirmed that an aircraft that could have been MH370 was last seen on military radar at 2.15am some 200 miles off Malaysia's west coast. | Malaysian military officials have previously confirmed that an aircraft that could have been MH370 was last seen on military radar at 2.15am some 200 miles off Malaysia's west coast. |
| Most of the disclosures on the nature of the search have come from anonymous US sources briefed by officials assisting the Malaysian investigation. Under international protocols, the country where the missing aircraft was registered must lead the investigation. | |
| Malaysian police have spent the past week investigating whether any personal or psychological problems affecting the crew or passengers may have had a role in the jet's disappearance, in addition to mechanical failure, hijacking or sabotage. Friday's revelations that the plane may have flown towards the Andaman Islands are the first real indication of a sinister cause. | Malaysian police have spent the past week investigating whether any personal or psychological problems affecting the crew or passengers may have had a role in the jet's disappearance, in addition to mechanical failure, hijacking or sabotage.

| Aviation experts from the UK – in addition to a team from Rolls-Royce, which manufactured the 777's engines – were due to arrive in Malaysia on Friday night to help with the investigation, said the civil aviation chief, Azharuddin Abdul Rahman. | Aviation experts from the UK – in addition to a team from Rolls-Royce, which manufactured the 777's engines – were due to arrive in Malaysia on Friday night to help with the investigation, said the civil aviation chief, Azharuddin Abdul Rahman. |
| A total of 57 ships, 48 aircraft and 13 nations are taking part in the search and rescue mission. Indian planes and ships have begun searching the 572 islands comprising the Andaman and Nicobar island groups using heat-seeking devices to help find the missing plane. | A total of 57 ships, 48 aircraft and 13 nations are taking part in the search and rescue mission.
