I just hope this new lead finding is not another false lead for the families.

However it will be sad to know everyone would most likely be deceased and I am sure that is just as aweful for the families as if the plane was still missing.

I feel so badly for the families.

Relatives of flight 370 passengers leave a 2 hour meeting in Kuala Lumpur... Have been told officials expect news within a few days they say
 
Earlier, the crew of the Poseidon told ABC News that their aircraft was getting radar hits of "significant size" in water's beneath the surface near the objects but that it was too early to tell if these hits were related to debris from the missing plane.

"This is a lead, this is probably the best lead we have right now, but we have to find them, see them, assess them," Young said of the objects.

"If there is a positive ID (of the debris) ... then (investigators) will likely study and model currents and flows in the ocean as soon as possible to find out where to look for the black boxes. Or, rather, listen for them, as they will likely still be sending out sonar signals at this point (about 30 days after an aircraft goes down)," Sidney Dekker, an expert on aviation safety, told USA TODAY in e-mailed comments.

Perhaps this has been posted, but does anyone have an ocean currents map?

No, but upthread this Australian article was posted:

Ocean expert Robin Beaman said debris could have been carried hundreds of kilometres since the satellite images were captured on March 16.
“The currents are drifting at one or two nautical miles per hour so it certainly makes sense that it could have drifted several hundred miles by now,” he said...The wind is moving in an easterly direction which means anything floating on the surface will also drift in that direction but at some point it just becomes waterlogged and sinks.”

If the plane entered the water on March 8 at or near its (ETA: western) fuel limit on the southern arc satellite-ping "red line", a steady east-ward drift of wreckage would lead right into the Australian search area. It's not conclusive, but suggestive:

Australian officials say the search for possible objects has ended for today.

Boeing Anti-Submarine Plane Joins Missing Jet Search

I really hope this is the plane. The families have been through so much in these last couple weeks and it would be nice if they could get some closure.

Sure, they'll probably never know (nor will we) what really happened the day the plane disappeared, but at least having bits and pieces of the plane found will be something.

If this debris did float from the original crash site, I really hope that search and rescue teams will be able to find it.
 
Yes. if you click on "helping out" under "crowdsurfing campaign", it takes you to Tomnod.

Here is a decent short article DigitalGlobe Powers Crowdsourced Hunt For Missing Malaysian Flight 370

DigitalGlobe used its satellites to capture some 3,200 square km of the area where the flight could have gone down....

...it shows the same images to many different people, and if enough people tag the same little square on the grid, an expert will review that area to see if the item of interest is worth investigating.

....the tedious legwork is done by what amounts to throngs of worker bees, thus freeing up the time and resources of the experts to do more sophisticated work.

Hi all, I was up all night and watching CNN.. I know nothing about planes, ships, even canoes so please dont think I am nuts. If they find these are parts of the plane can they send a submarine down there? It would be a blessing as they could really ID. it. My thoughts and prayers are with the families. I cant put the picture of the mom out of my mind.
 
Nope, the pilot on CNN said it was possible even if the plane were flying on autopilot and ran out of gas.

I was just passing along what he said. I'm not saying it would have been a smooth landing but it doesn't just drop out of the sky like someone (and myself) wondered previously in the thread.

That is very interesting. I see a CNN article where a pilot, Robert Goyer, talks about if the plane ran out of fuel, the auto pilot may have remained on and that the "dynamics such a crash scenario are complex." Without the engines or APU, there is no electricity to power the autopilot nor the control surfaces. Now, planes can deploy a ram-jet to provide minimal power to control things in such a case, so maybe the plane would do that on its own. I don't know. There is the case of AirTrans Airbus that ran out of fuel over the Atlantic and its pilots had to glide to an airport. Could a 777 autopilot attempt a water landing on its own without the engines and without pilot assistance? I have no idea.

"If the debris is from the plane, investigators would face a daunting task to retrieve the "black box" data and voice recorders needed to help understand what caused the disaster.

University of Western Australia Professor of Oceanography Charitha Pattiaratchi said that, based on currents in the area, if the debris is from the plane it probably would have entered the water around 300-400 km to the west.

The search area covered an ocean ridge known as Naturalist Plateau, a large sea shelf about 3,500 metres (9,800 feet) deep, Pattiaratchi said. The plateau is about 250 km (150 miles) wide by 400 km (250 miles) long, and the area around it is close to 5,000 metres (16,400 feet) deep.

"Whichever way you go, it's deep," Pattiaratchi said."

This is not a new concept. From 2000/2001 NASA has had a few experimental projects, mainly identifying craters on Mars with images from orbiters. IIRC it was called ClickWorkers.
 
WHat I don't get is why if they were headed to Lankowi, the reciprocal approach that he was planning to use (from over the water) was not already pre-programmed into the FMC as a "common, default or emergency alternate airfield". I am totally speaking from personal thought/opinion on this, but I would put money on it that every single aircraft in the Malaysian Airlines fleet bigger than a hang glider would have Lankowi as a preset for anything from an easy shortcut for crews entering flight data on pre-flight through to the above mentioned reasons... and I will tell you something else scary for those who live in aviation oblivious bliss... that airliner could have flown itself back to lankowi, put itself into the approach (providing lankowi has an ILS of course) and come to a complete wheels stop landing after touching down on the "Keys" at the end of the runway with a a rate of accuracy better than most humans can achieve...

...even if everyone on board had died just moments after the turnaround to track for LKW ...

Whoa, whoa, whoa. Do I understand that correctly - that the plane on auto-pilot could have landed itself? I mean, landed itself at the airport if they had put in the destination as the airport?

"The owner of a Norwegian car carrier said it planned to search through the night for two large objects sighted off Australia that could be debris from a missing Malaysian jetliner, despite the official search being suspended because it was too dark.

The Hoegh St. Petersburg was the first ship to arrive in the area where the two objects were spotted by satellite four days ago in one of the remotest parts of the globe, around 1,500 miles southwest of Perth, or about the distance from New York City to Dallas.

"We will continue searching during the night at reduced speed and with all spotlights available, and we will increase the speed again when the light comes back," Ingar Skiaker, Chief Executive of Hoegh Autoliners, told a news conference in Oslo.

"We have not had any report of any finds, but if or when they find something... the captain will report to the Australian authorities first," he said".
 
This is Air France - done by the French equiv of NTSB. THey model NTSB, however they are much more reluctant to release the actual transcript of CVR! It over 200 page so 10% is not problem.

Did it this way because it takes some to load the whole report!
