The plane which carried Queen Eizabeth II's coffin from Edinburgh to London on Tuesday was the world's most-tracked flight, according to Flightradar24.
The global flight tracking service said six million people attempted to click on the flight on its website within a minute as the C-17 Globemaster aircraft prepared to take off from Edinburgh Airport at just before 6pm last night, en route to RAF Northolt.
This caused "unprecedented strain", according to the company, which provides members of the public with real-time information about thousands of aircraft around the world, and caused the website to crash. Flightradar24 said it had "implemented a number of traffic calming measures" before the flight as it "expected a large influx of users", but the "immediate, massive spike was beyond what we had anticipated", according to Walesonline.
