Malaysia Airlines Flight MH370

The search for MH370, which disappeared carrying 239 passengers and crew on March 8, is already set to be the most costly in aviation history

A series of acoustic pings thought to be from the plane's black box recorders were heard near where analysis of satellite data put its last location

The company, Inmarsat, will release the data and methodology it used to calculate the plane's path in a week

The company is making the unlikely claim that the wreckage should be investigated as connected to Flight MH370, but the possibility was dismissed by authorities

The search for Air France Flight 447 off of Brazil took more than two years and cost $160 million

Authorities are confident they know the approximate position of wreckage of the Boeing 777

Nearly three miles under the Indian Ocean, a drone called the Blue-fin 21 will begin looking for signs of flight MH370

A military source says they watched an unidentified plane cross back over Malaysia, but they decided not to scramble the jets

An Australian authority said he was "optimistic that we will find the aircraft" after more ping signals were detected in the search for Flight MH370

Up to 10 planes and nine ships from a half dozen countries on Wednesday scoured a stretch of ocean roughly the size of Britain

The biggest mystery of Malaysia Airlines Flight 370 is why the airlines refuse to fully monitor planes

In a rough and remote corner of the southern Indian Ocean, over 100 objects that might be debris from Flight MH370 have been detected by satellite

The Malaysian prime minister said the Malaysian airliner that the plane ended its journey in the southern Indian Ocean

It's not clear if the objects were near other possible finds in a vast swathe of some of the most inhospitable sea territory on Earth

The larger of the objects measured up to 24 meters (79 ft), long and appeared to be floating on water several thousand meters deep, they said

An international effort is searching for the missing Malaysian plane over an enormous area, but authorities still don't know who diverted it, or why

Evidence suggests the flight was diverted hundreds of miles off course, sources say

The two men carrying stolen passports have been identified as Iranians with likely no connection to the plane's disappearance
