SUMMARY: MH370 departed Kuala Lumpur for Beijing with 227 passengers and 12 crew early morning March 8 2014. After what appeared to be a normal departure, a handoff to Vietnamese ATC was not finalized - communications and secondary radar data no longer were transmitted. The aircraft has been assumed to fly on for 7 hours on an initially circuitous route and to have been lost at sea in the southern Indian Ocean, 1,500 mi / 2,500 km sw of Perth.
No operating theory has been put forth that provides a probable explanation of who has flown the aircraft nor for what possible purpose as of 27 March. Link to BBC written and video summary of the flight of MH370.

The Chief Coordinator of the Joint Agency Coordination Centre, Air Chief Marshal Angus Houston (Ret'd), said an initial assessment of the possible signal detected by a RAAF AP-3C Orion aircraft yesterday afternoon has been determined as not related to an aircraft underwater locator beacon.
Friday, 11 April 2014 (BBC and other sources)
Australian leader Tony Abbott says authorities are confident that signals heard in the Indian Ocean are coming from the "black box" flight recorders of the missing Malaysia Airlines plane. Link
Thursday, 10 April 2014 - pm AWST (JACC)
The Chief Coordinator of the Joint Agency Coordination Centre, Air Chief Marshal Angus Houston (Ret'd), has confirmed that whilst conducting an acoustic search this afternoon a RAAF AP-3C Orion aircraft has detected a possible signal in the vicinity of the Australian Defence Vessel Ocean Shield.
"The acoustic data will require further analysis overnight but shows potential of being from a man-made source," Air Chief Marshal Houston (Ret'd) said.
"I will provide a further update if, and when, further information becomes available."

Wednesday, 9 April 2014 (BBC)
An Australian vessel heard the signals again on Tuesday afternoon and evening.
Signals heard earlier had also been further analysed by experts who concluded they were from "specific electronic equipment".
Experts at the Australian Joint Acoustic Analysis Centre had also analysed the first two signals heard over the weekend.
Their analysis showed that a "stable, distinct and clear signal" was detected. Experts had therefore assessed that it was not of natural origin and was likely from specific electronic equipment.

Up to 10 military planes, 2 civil planes and 13 ships will assist in Sunday's search for missing Malaysia Airlines flight MH370.
The Australian Maritime Safety Authority (AMSA) has three separate search areas planned for today about 2,000 kilometres north west of Perth, which total approximately 216,000 square kilometres.
Weather in the search area is expected to be good with a cloud base of 2,500 feet and visibility greater than 10 kilometres.
Reports overnight that the Chinese ship, Haixun 01, has detected electronic pulse signals in the Indian Ocean related to MH370 cannot be verified at this point in time.
Saturday 5 April 2014:
The Chinese maritime patrol ship Haixun 01 has picked up a 37.5 kHz pulse signal, according to Chinese media. Though there is no evidence it is from the MH370 "black box", the frequency is the same as used by fight recorders. (Xinhuanet, others)
5 April 2014—am - (JACC)
~10 military planes, three civil jets and 11 ships participated in today's search. ADV Ocean Shield and HMS Echo continued underwater search operations searching with TPL-25 towed pinger locator.
Weather was fair, with possible showers.

Monday, 31 March: (AMSA Update #31, 8.00am (AEDT) 0000 UTC
10 aircraft searching, no notable results. The ADV Ocean Shield was scheduled to depart from Perth today. It has now been fitted with a black box detector and an autonomous underwater vehicle. Some parts of the search area will experience low cloud and rain throughout the day.
Sunday, March 30, 2014 AEDT: The search activities continued in an area about 1,850 kilometres west of Perth, focused on an area of about 319,000 square kilometres. Eight aircraft were involved in today’s search.
Ten ships arrived or were on station today: HMAS Success, the Chinese Maritime Safety Administration ship Haixun 01, China Rescue and Salvage Bureau ship Nan Hai Jiu, and the Chinese Navy vessel Jinggang Shan.All ships in the search area were tasked to locate and identify the objects sighted by aircraft over the past two days.
Weather in the search area included light showers and low cloud, though search operations are expected to continue.
AMSA Update #28, 30 March 2014: 0645(AEDT)
Debris spotted and identified by ship turned out to be fishing debris - a fishing vessel is missing and the search for the vessel has now been discontinued after finding the debris. - AMSA
Saturday, March 29, HMAS Success, the Chinese Maritime Administration patrol ship, Haixun 01, PLAN vessel Jinggangshan (carrying two helicopters) were active Saturday; the later specifically is searching for debris, oil slicks, lifejackets, etc. Eight aircraft were also launched today. A IL-76 from China spotted some small colourful debris (orange, white and red), dropped a marker and left the debris to be checked by ship - the debris, recovered and checked by Haixun 01, was not related to MH370. Weather began nicely but has been deteriorating today; the search day is over now. (National News Agency of Malaysia, BBC and others.)
The ANZAC class frigate HMAS Toowoomba left Perth this evening and is due to arrive in the search area in about three days.
Friday March 28 local time end of search day: Ten aircraft searched an area of nearly 100,000 sq mi / 256,000 sq km today. Five aircraft spotted debris in the new search area; another aircraft spotted debris 546 km away.
● AMSA announcement PDF
The search area has shifted northeastward ~1,100 km / 700 mi based on the theory the aircraft was flying faster than previously believed (skewing the imputed flight path and decreasing range based on available fuel). The new search area is approximately 123,127 sq mi / 319,000 sq km and around 1,150 mi / 1,850 km west of Perth. Satellites are being redeployed to survey the new search area. (Aviation Herald, Malay Mail online and others; BBC article link)
The Malaysian government is expected to appoint an international panel on aviation security along with a parliament select committee to probe overall airline safety... an official said in Kuala Lumpur on Saturday (29 Mar 2014).
Tuesday, 26 Mar, search activities were halted by Sea State 7; resumed Wednesday, Thursday 28 Mar again saw aircraft withdrawn from search activities.
If potential debris is spotted by satellite, further identification must be done by aircraft, and then recovered by ships for analysis. If debris proves positive from MH370, further analysis must determine drift distance and angle to a possible crash site. This all depends on the weather holding as well, though at least the search is no longer focused in the "Roaring Forties".
Soon, a US Navy Towed Pinger Locator will be towed by the HMAS Ocean Shield to try to detect "pings" from the aircraft's "black box", which is actually orange and consists of the Cockpit Voice Recorder (two hour loop) and Flight Data Recorder (25 hours continuous).
● BBC page on "black box" link
● BBC video "black box" search link.
If air and sea search fails, or further narrowing of the search area is required, sonar will be deployed and used. Support and research vessels, some of them with sonar and one with the U. S. autonomous underwater Bluefin 21, will then try to find the wreck amongst the sea bottom topography.
● BBC sonar search video link.
Information reveals that Malaysia Airlines chose not to add an upgrade to aircraft communications ("Swift") that could have continually transmitted aircraft data even with ACARS shut down. Rather than pay the cost of USD $10.90 per flight, MH opted to download the data to a USB thumb drive after the end of a flight, according to various sources. http://www.washingtonpost.com/world/...f19_story.html
Monday, 24 March, Malaysian prime minister announced that new satellite data showed that flight MH370 crashed into the Indian Ocean. In a brief statement he said: "It is with deep sadness and regret that I must inform you that... flight MH370 ended in the southern Indian Ocean." The ongoing multinational search operation would continue as they seek answers to the questions which remain.
Partners Inmarsat and SITA AIRCOM, UK and US aviation safety and security officials have determined MH370 may have flown up to seven hours beyond the point of last radar location; MH370 apparently broadcast automated hourly engine maintenance code "pings" received by satellite operator Inmarsat.
New satellite analysis techniques developed by British firm Inmarsat and the UK's Air Accidents Investigation Branch (AAIB) have "concluded that MH370 flew along the southern corridor, and that its last position was in the middle of the Indian Ocean", said Malaysian PM Najib Razak.
"This is a remote location, far from any possible landing sites. It is therefore with deep sadness and regret that I must inform you that, according to this new data, flight MH370 ended in the southern Indian Ocean."
Debris is being searched for, but the USA is sending a Towed Pinger Locator towed sled equipped to find "pingers" such as the "black box" pinger, which is designed to be powered for 25 - 30 days.
A number of aircraft, including four long range commercial planes, three RAAF and one RNZAF P-3 Orion anti-submarine surveillance aircraft, one USN P8 Poseidon, two Chinese IL-76 and two JASDF P-3 Orion aircraft are searching, joined by a Korean (ROKAF) P-3 Orion and C-130H. The ASW aircraft have observation ports for observers, Magnetic Anomaly Detector gear and can deploy various sonobuoys, etc.
Chinese, British and Australian naval ships have joined Australian supply ship HMAS Success, including China's ice-breaking Xuě Lóng (Snow Dragon) research vessel, (involved in the recent Antarctic rescue of the MV Akademik Shokalskiy) and three Chinese PLAN warships QianDaoHu, KunLunShan and Haikou, as well as merchant ship Zhonghai Shaohua, are participants as well. The U.K. is sending HMS Echo to join the search (has departed the Maldives), China is sending more vessels.
The HMAS Ocean Shield will be fitted on 28 Mar with the US "TPL" (Towed Pinger Locator) and "...is expected to reach the search area by 5 April, giving it only two days before the pinger's batteries possibly start to fade at 30 days."
The US is sending a UUV (autonomous unmanned underwater vehicle) Bluefin-21, designed by Bluefin Robotics, equipped with side-scanning sonar and a "multi-beam echo sounder" which can examine underwater objects in detail and operate in depths of up to 4,500 metres (14,700 ft) (BBC).
Malaysia has asked the FBI to help recover data it said was deleted from a home flight simulator belonging to the plane's chief pilot, Captain Zaharie Ahmad Shah, but otherwise no evidence has emerged to implicate him or the crew. FBI announced on 26 Mar a couple of more days are needed, but so far they have found no forensic evidence against Capt. Zaharie.

NOTE: While links to relevant and reasonably reliable news sources are welcome, please take a few minutes to scroll back a couple dozen posts to make sure a similar story hasn't already been posted. There have been many well-meaning posters eager to share “breaking news” that ends up having been posted by others hours before. Thanks for helping us to avoid redundancy and repetition!
Time Frame Confusion
Sources may appear to be reporting conflicting timeframes for various stages of the incident. However, this is likely due to confusion about time zone changes between Malaysia (last ATC contact) and Vietnam (next ATC contact) - see time zone map here for boundaries. Please report times in UTC/GMT wherever possible.
SAR / Search and Rescue Recovery Operations Investigation
NOTE: Discussion of opinions and perspectives on SAR costs and timeliness, which involves coordination of 26 nations' civil and military authorities, is beyond the scope of this thread. Users have been advised to shift such discussion to OMNI - see post #2047. Thanks for your cooperation.
Reports indicate latest satellite ping around 0811 MYT (0011 GMT/UTC/Zulu), or nearly 7 hours after contact was lost.
Boeing and Rolls Royce have teams on site; the NTSB (USA) and UK AAIB are involved due to US and UK manufacture of aircraft and engines, France's BEA due to AF447 similarities and other resources are likely to be invited to assist. The U. S. FBI has become involved in investigating the crew, passengers and ground staff.
Reports that the aircraft climbed to 45,000 feet, above its service ceiling, and as low as 5,000 ft remain unverified. More here and in posts #3894 on.
Malaysia Airlines has issued a statement that the shipment of lithium-ion batteries was in compliance with the International Civil Aviation Organisation (ICAO) and the International Air Transport Association (IATA) requirements, where it is classified as "non-dangerous goods".
Disproven Reports to Date
Early reports that the plane had landed in Nanming, Vietnam or Nanning, China, have been disclaimed by Chinese authorities and MH leadership.
All reports of possible aircraft debris, up to and including a possible debris field off the southeast coast of Vietnam, China SASTIND satellite imagery from 9 Mar debris reported 105.63 east longitude, 6.7 north latitude investigated 12 Mar have been discredited. The latter is now "a mistake", according to SASTIND. Read more here.
Possible fuel slicks identified early on have been tested and determined NOT to be aircraft fuel.
Various life rafts found in the SAR ops area have been unrelated to the missing aircraft. See one example at this post.
Reports of another pilot contacting MH370 have been discredited.
Reports of passenger cell phones still ringing when called are almost certainly an artifact of international telephony - see explanation by one FTer at post #1832.
All claimed ground observations of the aircraft (Malaysia, Vietnam oil platform, etc.) data are unverified at this time.
Beware of data from sites like FlightRadar24, FlightAware, etc. These data are not entirely reliable, as they are synthesized; erroneous readings may be present on some sites. The aircraft could not climb to 49,500 feet as some sites may indicate, as this is considerably above the aircraft's design ceiling.
Authorities deny that five other passengers checked in for the flight, but did not board, stating the pax were actually no-shows who never checked in, and that no baggage was loaded for these five pax. Four standby passengers were accommodated.
Reports of seismic readings being possibly related to the aircraft crashing into seafloor have been described by experts as improbable. USGS records a natural earthquake off the west coast of Sumatra - info here
Other speculation (EMP, shot down, etc.) has been mentioned in the thread but currently has no basis, and is not appropriate for this thread. Please observe the moderator note at the beginning of this wiki.
NOTE: flight number MH370/371 will be renumbered MH318/319 effective 14 March 2014
!!! REMINDER !!!
This thread is about the loss of MH370. In depth discussion of unrelated topics — geopolitics, passport theft, aviation security, airport security procedures, etc. — belongs in other fora. A few include:
OMNI/PR: Discussion of perspectives on politics and religion, including geopolitics and terrorism (requires 180 days on FT and 180 constructive posts prior to admission)
Of particular interest is the ATSB's Progress Report section, which has a map posted on it. The map has 'Priority Search', 'Medium Search' and 'Wide Search' areas labeled on it. On the bottom right corner of the map are "Day of Release" and "Map Number" labels, so I presume this map will be regularly updated.
The website also includes MH370 external links, Frequently Asked Questions (FAQs), an explanation of the 7th Arc, Definition of Underwater Search Areas, Three-dimensional models of the seafloor terrain and Bathymetry Survey Data.
I also assume that this ATSB website was the source for the BBC News article above.
