A deep sea search vessel commissioned by the Egypt government to the crash site of EgyptAir flight MS804 has recovered all known human remains from the wreckage, Reuters reported. The remains were handed over to officials at Alexandria, the investigation committee confirmed. The vessel, named the John Lethbridge (pictured above), will return to the underwater site to check for any other possible remains.

The flight went missing on May 19 with 66 people on board before it crashed into the Mediterranean Sea. Investigators said the plane plummeted around 23,000 feet, and turned twice, before it went missing and was found in the sea. The aircraft’s two black boxes were recovered from the Mediterranean Sea around two weeks ago, and contains recordings from the cockpit. Investigators have not ruled out that the flight could have been deliberately brought down.
