Every year billions of people travel around this planet using ships, trains and, of course, airplanes. Now, we all know that humans don’t come with the natural ability to fly and we’ve had to slowly learn and perfect that part of our lives over time. In fact, for the last 100 years, or so, we’ve been steadily improving our time in the sky. Sure, your legroom and comfort may not be increasing, but the level of safety is. Specifically, the odds of you being in a plane that collides with another plane has dropped dramatically. Thanks to old and new technologies, flying is only getting safer. To prove it, we’ll show you just the techniques and technology airlines use to ensure your plane doesn’t collide with another plane.
