The British investigators have recovered a body in the wrecked plane carrying Argentine footballer Emiliano Sala.
The bad weather has forced the Air Accidents Investigation Branch (AAIB) to abandon hopes of pulling the plane to shore on Wednesday.
The plane, a Piper PA-46 Malibu, was carrying the former Nantes footballer to his new English Premier League team Cardiff City when it disappeared near the island of Guernsey on January 21, along with pilot David Ibbotson.
The AAIB who then took over the operation revealed on Monday that an unidentified body had been found at the site.
“In challenging conditions, the AAIB and its specialist contractors successfully recovered the body previously seen amidst the wreckage,” the Air Accidents Investigation Branch (AAIB) said Wednesday.
“The operation was carried out in as dignified a way as possible and the families were kept informed of progress.”
However, attempts to recover the aircraft during the underwater operation were unsuccessful.
“The weather forecast is poor for the foreseeable future and so the difficult decision was taken to bring the overall operation to a close,” the statement added.
It said that extensive video footage captured by a remotely operated vehicle is expected to “provide valuable evidence for our safety investigation,” adding that it intends to publish an interim report on the accident later this month.
The recovered body will be now be passed to the coroner for identification.
