So many people tried to track Queen Elizabeth’s final flight they crashed the app

So many people tried to watch the plane carrying the coffin of Queen Elizabeth II from Edinburgh, Scotland, to London on Tuesday using a popular flight tracking app that the service crashed.

"We are currently experiencing heavy load and are working to bring the service back as soon as possible,” read the message on FlightRadar24.com, shortly after the Royal Air Force Boeing C-17 Globemaster III took off from Edinburgh Airport en route to RAF Northolt in London.

According to the company, nearly 6 million people attempted to follow the queen’s final flight moments before its departure, causing “disruption to our platform.”

The service was brought back online during the one hour flight, but less than 300,000 were tracking it by the time it landed.

The queen’s coffin — which had been on display at St. Giles’ Cathedral in Edinburgh — was transported to Buckingham Palace, where it will stay before lying in state at the Palace of Westminster on Wednesday.

Princess Anne and her husband accompanied the coffin on the flight from Scotland to England.

On Thursday, after the palace disclosed that the queen’s doctors were concerned about her health, more than 100,000 people tracked a plane carrying Prince William, Prince Andrew, Prince Edward and Sophie Wessex from London to Aberdeen, Scotland, as members of the royal family rushed to Balmoral Castle to see the 96-year-old before her death.

And more than 150,000 people tracked the jet carrying King Charles III and Queen Consort Camilla from Aberdeen Airport to RAF Northolt on Friday. It marked Charles's arrival in England for the first time since his accession to the throne.
