FIRST ON 7: An Adelaide-based exploration company believes it may have located the wreckage of Malaysia Airlines flight MH370, 5000km away from where authorities have been looking.
The company, GeoResonance, says its research has identified elements on the ocean floor consistent with material from a plane.
Six weeks have now passed since the plane disappeared and extensive searches in the Indian Ocean have failed to locate any wreckage.
Today, Prime Minister Tony Abbott admitted the chance of finding debris on the surface is slim to none.

He said efforts will not focus on the ocean floor, but GeoResonance believes authorities have been looking in the wrong place.
It started its own search for the missing aircraft on March 10.
“The technology that we use was originally designed to find nuclear warheads, submarines… our team in the Ukraine decided we should try and help,” David Pope from GeoResonance said.
The company surveyed over 2,000,000 square kilometres of the possible crash zone, using images obtained from satellites and aircraft.
Scientists focused their efforts north of the flight’s last known location, using over 20 technologies to analyse the data including a nuclear reactor.
They could not believe what they found in the Bay of Bengal.
“Our team was very excited when we found what we believe to be the wreckage of a commercial airliner,” Mr Pope said.
Pavel Kursa from GeoResonance told 7News: “We identified chemical elements and materials that make up a Boeing 777… these are aluminium, titanium, copper, steel alloys and other materials.”
An initial report was sent to authorities while the black box still had two weeks of battery power.
The team then verified its findings by analysing images from the same area on March 5, three days before the plane disappeared.
“The wreckage wasn’t there prior to the disappearance of MH370,” Mr Pope said.
The full report was delivered on April 15.
“We’re not trying to say that it definitely is MH370, however it is a lead we feel should be followed up,” Mr Pope told 7News.
7News tried to contact the office of search co-coordinator Angus Houston today but there was no response.
If that had happened then atleast one of the 4 ELTs onboard would likely have activated -- and yet none of them did.
Depends on how it hit. Then too, nobody knew exactly where it went down. Nobody heard any ELT signals. If they landed on some remote runway for whatever reason, I bet everyone’s dead by now.
Obviously, they took the wings and tail assembly off it for the trucking.
The airplane sank only partially. The left engine came off and sank in 65 feet of water.

It was judged to be a write-off, although one salvage company claimed that, if it had been salvaged properly, it could have been repaired for only $20m, a third the cost of a new airplane.

According to the manufacturer, Dukane Seacom, the frequency is 37.5kHz ± 1kHz. Nine milliseconds, approximately once per second. They also make a model that operates on 8.8kHz. They claim, "The lower frequency acoustic signature of the DK180 travels farther than existing ULDs thus improving locating efforts."
The protocol allows for the pinger detector to send a signal to get the aircraft id and air craft serial id number.
The data sheet makes no mention of encoding any information into the ping, although that would obviously be nice. But, really, how many sources of nine millisecond pings once a second on that frequency can there be in the South Indian Ocean?
I would think a two-way protocol would lengthen battery life by requiring the pinger to send only when it receives a poll from a search vessel. However, ensuring that the device can hear a poll reliably would be a challenge and an additional point of failure.
A two-way protocol would also allow a single search vessel to get ranges to the pinger from a number of different points, allowing its position to be determined. However, if there are multiple search vessels within range of a send-only beacon, they can compare ping arrival times and work out its location from that data, combined with their own positions at the time.
Remember the Air France plane that pancaked
***********************
Air France belly flopped at terminal velocity ,, and it was an Airbus so of course the tail fell off well before it hit.. we don’t know how this one landed, if it landed well there will be minimal debris.
not including Airport ‘77
*******************
That was a movie... in real life the plane would have filled with water in minutes ,, and as the pressures in and out would be equal the fuselage would remain intact.
Right now it’s all speculation.
