The Titanic memorial cruise - tracing the route taken by the liner 100 years ago - has been forced to take a short detour after a passenger was taken ill.
BBC cameraman Tim Rex, 56, was airlifted off the MS Balmoral by rescue helicopter as a medical precaution.
The Balmoral, which left Southampton on Sunday, had headed back towards the Irish coast to enable the rescue.
The ship is still expected to arrive at the wreck site in time for scheduled memorial services at the weekend.
The Balmoral set sail from England's south coast on Sunday, travelling near Cherbourg in north-west France and stopping off at Cobh in the Irish Republic, before setting off for the North Atlantic spot where Titanic went down.
The Balmoral had been carrying 1,309 passengers - the same number of paying guests as were on the Titanic - including relatives of those who died, authors and historians.
The cruise - which is scheduled to last 12 nights, travelling between Southampton and New York - has attempted to recreate Titanic's original voyage.
Many passengers and crew are dressed in period costumes, while guests have been able to eat meals from Titanic's original menu and attend lectures by historians and experts.
More than 1,500 passengers and crew died when Titanic hit an iceberg on the night of 14 April 1912 and sank several hours later.
