Experts hunting for Malaysia Airlines Flight MH370 have discovered wreckage on the seabed. However, it's at least 100 years old and has nothing to do with the missing jet.
Authorities sweeping the floor of the southern Indian Ocean for traces of the vanished Boeing 777 found what appeared to be a man-made object in December, according to a statement issued Wednesday by the Australian government.
An investigation using an underwater drone found the object was merely a shipwreck, officials said.
Experts at the Western Australian Museum said the wreck was likely a steel or iron vessel from the "turn of the 19th century," according to the statement.
It is the second time searchers have come across a wreck, the first discovery coming in May last year.
MH370 vanished carrying 239 passengers and crew from Kuala Lumpur to Beijing in March 2014.
At least part of the mystery was solved last year after a wing-part found on the remote Indian Ocean island of La Reunion was confirmed as having come from the jet.
Three ships are still scouring the miles-deep ocean floor, but have found no trace of the plane despite a 22-month search covering an area the size of South Carolina.
The search will eventually cover an area the size of Pennsylvania and is expected to be completed in the middle of this year.
