Titanic film director James Cameron has called the hunt for a missing submersible a “prolonged nightmarish charade”.
Oscar winner Cameron – who has visited the Titanic wreckage site 30 times – said the fate of the five people on board the Titan was known days ago.
Mr Cameron said he knew the exact location of the submersible yet rescuers talked of oxygen supplies lasting for hours and hearing “SOS” knocking sounds.
He told the BBC:
“The search felt like a prolonged and nightmarish charade where people are running around talking about banging noises and talking about oxygen and all this other stuff’.
“I knew where that sub was sitting – exactly underneath its last known depth and position.
“That’s exactly where they found it.”
The five people aboard the Titan died instantly when the submersible suffered a “catastrophic implosion” just 1,600ft from the bow of the wrecked ocean liner.
A remotely operated submarine from a Canadian ship found debris on the ocean floor.
Navy officials believe the five died on the Sunday.
