Malaysia Airlines says one of its planes has gone missing on the way from Kuala Lumpur to Beijing with 239 people on board.

A statement from the airline says flight MH370 lost contact with air traffic controllers at 2:40am local time, just over two hours into the flight.

The plane, a Boeing 777-200, left Kuala Lumpur at 12:41am on Saturday, and had been due to arrive in Beijing at 6:30am local time.

The company says the plane was carrying 227 passengers, including two infants, and 12 crew members.

The airline says it is contacting the next-of-kin of all passengers and crew, which includes people of 13 different nationalities.

In a statement on the airline's website, group chief executive officer Ahmad Jauhari Yahya said the airline was working with authorities to locate the aircraft.

"Focus of the airline is to work with the emergency responders and authorities and mobilise its full support," the statement said.

"Our thoughts and prayers are with all affected passengers and crew and their family members."

The airline says it will provide regular updates on its website.

The ABC understand Malaysia Airlines will hold a press conference on the incident shortly.

to monman:

.....you and others have posted incorrect details about the distance black box signals transmit over......so how the dickens can anyone believe what you post?

...."..John Goglia, a former board member of the National Transportation Safety Board, the US agency that investigates plane crashes, said the lack of a distress call suggested that the plane either experienced an explosive decompression or was destroyed by an explosive device. 

    "It had to be quick because there was no communication," Goglia said.

"...

Finding planes that disappear over the ocean can be very difficult, and it can take days before wreckage is located. Airliner ‘‘black boxes’’ — the flight data and cockpit voice recorders — are equipped with ‘‘pingers’’ that emit ultrasonic signals that can be detected underwater.

Under good conditions, the signals can be detected from several hundred miles away, said John Goglia, a former member of the U.S. National Transportation Safety Board. If the boxes are trapped inside the wreckage, the sound may not travel as far, he said. If the boxes are at the bottom of an underwater trench, that also hinders how far the sound can travel. The signals also weaken over time...."

Another crackpot scenario: " the official command to all search parties was to change course and search in the opposite direction for a bit -in the Strait of Malacca was far enough away.....then they were called back later to resume searching same area and a widened area."

There  certainly is a lot of broken china around.

I know you C&P Wiki stuff without appreciating the content P007, but  try current media sources e.g.

"Searches continued around the Gulf of Thailand, but Malaysia is also focusing on the Straits of Malacca
Malaysia has extended the massive search operation for the plane to the Malacca Strait after initially focusing on the South China Sea."

ABC's Samantha Hawley in Kuala Lumpur  excerpt from press briefing

 "That is why we're searching in two areas. That's why we are deploying all our best resource and also aircraft and from the neighbouring countries in these two areas."

paintsew, you've put forward lots of ideas about what may have happened. 

Do you have ideas as to why?  Why would they, whoever they may be, want to get rid of a plane load of civilians, most of whom were probably just going on holiday?  It just doesn't make sense.

.The logic behind my thinking is simply that a plane does not just vanish, if someone downs it there is going to be wreckage. The big mystery is why none of this wreckage despite some earlier reports has been found

Yet in another post you suggested it could have been vaporised, thereby leaving no debris.

No, planes don't simply 'vanish' but in order to find a downed plane you have to be looking in the right place and in order to look in the right place you have to have a reasonably good idea of where the right place is. As I understand it, the area they are searching covers thousands of square miles. Needles and haystacks?

The signal given off from the black box is only detectable over a distance of two miles. I would hazard a guess - and I'm sure John will correct me if I'm wrong - that there have been very few, if any, cases where a black box signal has actually led searchers to an underwater  wreck site.

I also find it puzzling that of all the possible scenarios you would choose the most wildly improbable to focus on.

"John Goglia said the lack of a distress call suggested that the plane either experienced an explosive decompression or was destroyed by an explosive device.
However, P007 whilst those are possibilities, he did not mention the obvious example of the Air France accident: no distress calls. no explosions,  but pilot error, and an intact aircraft crashing into the sea.

As for you C&P apropos the supposed comment from Goglia about ULBs: Under good conditions, the signals can be detected from several hundred miles away. That is totally incorrect (or even technically feasible) as anyone with small amount of scientific knowledge would know. Do you ever bother to research at all?
 I suggest that comment is from a not very bright reporter with like readers.

Let me offer some technical information from reputable sources.

1. Report to Bureau d’Enquêtes et d’Analyses (BEA)
   Search Analysis for the Location of the AF447 Underwater Wreckage

Ships employed Towed Pinger Locators (TPLs) supplied by the US Navy;The TPL sensors were assessed to detect the ULBs at a lateral range of 1730m with a POD of 0.90. This detection range accounted for the frequency of the ULBs’ emissions (37.5 kHz) and the assumed source level (160 dB)      Pretty standard ULB output P007

So again , I will give you 2km, easy to find?

P007 - I usually hit the reply button on the last post..others do that too.. It doesn't mean we are replying to that person. It is not possible now to make s reply without another's id in the reply box now ( it used to be),

I have purposely chosen one of your posts to reply to this post so you don't get confused.

I don't make replies 'through' other posters.

If I choose to kudo another poster, that is my business. I don't expect to be criticised and/or targeted for doing that.

I dont know why you keep addressing some of your posts to me. I have not responded negatively or made personal comments on any of yours. I mostly don't read them and learnt early on here not to comment on your posts as that leads to ongoing harassment from you.

TGSE,  it is interesting to note that the UK MOD have stipulated that their aircraft , in  addition to the standard civilian ultrasonic  ULBs,  (37.5 kHz),  must also carry a MOD version that operates at 9.6 kHz which has an increased detection range  of 10km, can be detected by any  military ship or submarine at high speed, and can be detected by anti submarine sensors including air dropped sonar detectors and helicopter dipping sonar. There is now a move to lower the military ULB frequency to 4KHz which will increase the detection range to 25km. and still be in the military location envelope.

It is similar to the fact that you can hear a whistle nearby and know its  direction, but thunder a lot further away but only the rough direction it comes from.

I am still concerned that apparently no official request has been made to the experts in this field, namely  the military (US Navy & its civilian contractors) and also their French/British counterparts.

Even ten miles is a bit 'needles and haystacks' over an area of thousands of square miles of open water.

I saee the latest theory is that it may have flown on for another four hours and north korea could have been involved. Well of course it COULD have flown for that long - it was only  two hours into a six hour flight - but is it really credible that in all  that time nobody saw or tracked it?

My theory is that it was spirited away to the same place as all those planes that didn't really hit the Twin Towers or the Pentagon on 9/11

Actually TGSE it has been hijacked to add to the evil chemtrailers fleet, and the passengers used as forced labour in loading the evil chemicals
