Ever wondered what a F/A-18 Hornet Fighter sounds like when it takes off? Like this. If you've got headphones on, you might want to lower them all the way down before you click play.

Taken by an actual ground crew member with a GoPro camera strapped to his helmet, it shows him running through the final checks a fighter jet has to go through before it's launched off the flight deck of an aircraft carrier.

You might say he's ready to fly right into the... Danger Zone. *sunglasses*
