Planes Have 'Air Highways' in the Middle of the Sky

Taking a transatlantic flight can be scary for some travelers, but did you know that there is actually an invisible highway spanning the great ocean? Routes from the US to London are some of the busiest spaces of air traffic every day, so naturally air traffic controllers have come up with methods to keep everyone safe and orderly on the trek. For most of the route, planes are outside of radar signal, so communication with controllers on the ground is impossible. Due to this expansive 'dead zone,' tracks are laid out to help guide planes safely to London or the US respectively. Check out the video above to learn a little more about the invisible highways in the sky.
