Insane video gives perspective on how fast planes actually fly
Travelling by plane has become second nature.
Most of us pack our bags, head to the airport and hop on the airplane without much of a thought of how it all actually works. After all, the only time you really remember you're actually in a metal box flying through the sky is when you hit a bit of turbulence.
So, chances are you've never thought about how fast you're actually going - because it's practically impossible to tell when you're sat inside the plane.
A video posted on X, formerly known as Twitter, shows just how fast airplanes go - but if you're a nervous flyer, you might want to look away now.

While commercial aircrafts fly at different speeds, it tends to be around 550-600 mph - which are no small numbers.
It's fast, sure - but there could be a reason why the video seems extra speedy.
One X user commented under the post: "The speed, visually, is doubled, because both planes are travelling towards one another.
"For a proper perspective they would need to be viewing from below (stationary) or from the side at a 90 degree perpendicular angle."
And there's a reason why you barely notice you're travelling at such high speeds when you're actually up in the air. Someone else explained underneath the video: "Despite these high speeds, the smoothness of the flight often makes it feel less intense than ground transportation at equivalent speeds."
And in all honesty, those speeds have nothing on the Concorde - which had a cruising speed of 1350mph, which is more than twice the speed of sound.
The Concorde aircraft was retired back in 2003 - but a successor could soon be on the way.
NASA recently unveiled the new X-59 quiet supersonic aircraft, and it's been dubbed the 'son of the Concorde'. NASA Deputy Administrator Pam Melroy said it will "help change the way we travel, bringing us closer together in much less time".
The X-59 is expected to fly at 925 mph, and is set to take its maiden flight later this year. While it will probably take a while before traditional airlines like Delta or United start using jets like this in their fleets, NASA is keen to highlight it's not a prototype - it's a 'unique experimental airplane' that soon could become a reality.
