Mesmerising footage has shown how more than 202,000 flights took off and landed around the world in one of aviation's busiest days in history last week.

Flight monitoring service FlightRadar24 released the animated map showing aircraft filling the skies around the globe on Friday.

And it announced that it was one of the busiest days it had ever recorded since being founded in 2006, after it tracked a massive 202,157 planes.

Yesterday was the busiest day of the year in the skies so far and our busiest day ever. 202,157 flights tracked! The first time we've tracked more than 200,000 flights in a single day on https://t.co/krDfUYSbzK pic.twitter.com/ApCMHaVEQp

The Swedish-based website added that it was the first time it had ever tracked more than 200,000 flights in a day and that at the peak time, over 19,000 flights were in the air at the same time.

Writing on Twitter on Saturday, FlightRadar24 said: "Yesterday was the busiest day of the year in the skies so far and our busiest day ever. 202,157 flights tracked! The first time we've tracked more than 200,000 flights in a single day."

However, the service admitted that it was not possible to say for certain if there had never been more flights flown on a single day in adding it was only the busiest in history for them.

Flightradar24 describes itself as "the world's most popular flight tracking service, turning your phone, tablet, or computer into a virtual air traffic radar showing detailed aircraft and flight info for flights worldwide."

It combines data from several data sources including ADS-B, MLAT and radar data that is aggregated together with schedule and flight status data from airlines and airports to create its service.

The website also said the least busiest day tends to be Christmas Day, as most passengers travel before or after the big day.

The figures from FlightRadar24 come as the Transportation Security Administration (TSA) in the US projected that last Friday would be its busiest day ever, with agents screening more than 2.7 million people at airports.

The Transportation Security Administration said it expected to screen more than 28 million passengers and airline crew members between last Thursday and July 9.

The TSA's single-day record of screening 2.71 million people occurred the Sunday after Thanksgiving in 2004. The Friday before the July 4 holiday last year is the third-busiest day on record.
