The flight taking the Queen’s coffin to London was the most tracked in history, website Flightradar24 has said.
Nearly six million people tried to follow the plane’s route from Edinburgh to RAF Northolt within its first minute in the air, the website said.
The huge traffic caused disruptions to the site, where users can track the path of planes in the air.
More than 4.79 million people watched on its site and app and 296,000 were watching on a YouTube stream, it said.
The previous record was when a flight carrying US politician Nancy Pelosi to Taiwan last month was followed by 2.2 million people on Flightradar24.
The Queen’s coffin was flown on an RAF Globemaster C-17, after lying in state at St Giles’ Cathedral in Edinburgh.
The flight used the callsign “Kittyhawk”, used for any military flight with the Queen on board.
Princess Anne and her husband Sir Timothy Laurence accompanied the coffin, with the princess saying she had felt fortunate to be able to share the final hours of the life of her “dearest mother”.
“It has been an honour and a privilege to accompany her on her final journeys,” she added.
