(CNN) — The plane carrying Queen Elizabeth II’s coffin has broken records to become the most-tracked flight ever.
That number is derived from two sources — 4.79 million people who followed the flight’s journey on Flightradar24’s website and mobile app, plus an additional 296,000 who tracked the plane on YouTube.
The Royal Air Force plane carrying the Queen spent one hour and 12 minutes in flight. It landed at RAF Northolt, a military station about six miles from Heathrow Airport in Greater London.

Flightradar24 is one of several increasingly popular plane-tracking tools. The site began in Sweden in 2006 and became publicly accessible three years later.
Ian Petchenik, the website’s director of communications, told CNN Travel that the resulting traffic spike “was certainly our first foray into international events, and how displaying air traffic to the public in real time could influence how people were thinking about world news.”
Before Pelosi’s Taiwan visit, the most popular flight search on Flightradar24 was opposition leader Alexei Navalny’s flight back to Russia, where he was going to be put in prison upon arrival in 2021.
Flightradar24 staffers knew that the Queen’s final air voyage had potential to become tremendously popular. Their team tried to provide as much website stability as possible, but the massive influx of new users proved a technical challenge.
“This immediate, massive spike was beyond what we had anticipated,” Petchenik wrote in a blog post. He added: “In total we processed 76.2 million requests related to this flight alone — that’s any action by a user, like clicking on the flight icon, clicking on the aircraft information in the left side box, or adjusting settings.”
He predicts that this particular flight search record will remain unbroken “for a long while.”
