A search has resumed for the pilot of a light aircraft which crashed off the coast of North Yorkshire.
The alarm was raised on Friday afternoon after a two-seater plane was seen coming down into the sea close to Robin Hood's Bay.
A major search went on late into Friday night, but was scaled down after an object, thought to be the aircraft, was found submerged.
The Maritime and Coastguard Agency said there were no signs of a survivor.
The aircraft involved is believed to be a Piper 38, which left the Teesside area earlier on Friday.
A coastguard spokeswoman said on Friday night: "The lifeboat teams believe they have located the aircraft below the surface of the water. There were no signs of a survivor.
"They will be having another search from around midnight at low-tide.
"They need to identify if that is the aircraft involved but they think that it is."
Humber Coastguard said one person had been on board the plane, which transmitted a Mayday message.
Watch manager Mike Puplett said debris including carpet and a shoe was found about an hour after the plane crashed.
Mr Puplett told BBC News: "We took several 999 calls from members of the public at about 1620 BST this afternoon.
"They all came from the Robin Hood's Bay area and they all reported seeing a light aircraft falling and plummeting into the sea very close to the shore."
