An air-and-sea search has been stood down off Pembrokeshire's north coast amid reports that a light aircraft may have crashed into the sea.
Milford Haven coastguards said residents in Trefin reported hearing a loud blast after a low flying aircraft went overhead at around 19:10 GMT.
The Ministry of Defence quickly said that none of its jets were involved.
A rescue helicopter from RAF Chivenor as well as two all-weather RNLI lifeboats were involved in the search.
Coastguard rescue teams as well as police, the fire service and ambulances were also called to the area between Fishguard and St Davids.
But the search was called off at 21;20 GMT.
The RNLI said its lifeboats were returning to their bases.
The search was launched after coastguards said they received numerous calls from villagers reporting aircraft noise followed by a loud bang or blast.
"Heard it circling'
Sue Whitmore, who runs the Old School Hostel in Trefin, said she had heard what sounded like a light aircraft circling overhead.
She said: "I didn't hear the bang. I heard it circling," She described that kind of noise as "very unusual especially at night".
"A few minutes ago I heard a helicopter going over towards the sea and a lot of emergency vehicles have gone past."
She said other villagers had told her they had also heard an aircraft followed by a bang.
At the Ship Inn pub people report the emergency services have been searching an area between Trefin and St Nicholas.
"There are lot of emergency services," said one bar worker.
An MoD spokesman later confirmed that the reports did not relate to a military aircraft.
