A British satellite company says authorities have yet to search what it believes is the most likely crash site of the missing Malaysian jet.
Authorities recently finished up an unsuccessful, two-month-long search of 850 square kilometers of southern Indian Ocean seabed.
The search location was determined based on electronic signals sent from the plane to a communications satellite owned by Inmarsat.
An Inmarsat official told the BBC on Tuesday that the location searched was "further to the northeast than our area of highest probability."
He said an Australian ship was originally headed to the so-called "hotspot," but was distracted by signals thought to be from the missing jet's black box.
Australian officials have defended its choice of a search area, saying the "pings" were the best available leads at the time.
The Malaysia Airlines Boeing 777 was headed from Kuala Lumpur to Beijing on March 8 when it disappeared with 239 people on board.
The massive, multinational search has been temporarily paused while ships carry out a complex, months-long survey of the Indian Ocean floor.
Officials plan to use the survey data to determine the best location and equipment needed to continue the underwater search.
