Why Do Airports Spend Millions on These Bridges? 😲

[00:00:00]If you can board a plane using simple stairs, why do airports spend millions installing those giant jet bridges? And on top of that, they can even be dangerous and cause serious accidents.

[00:00:09]But the truth is, early airports really worked exactly how you imagined.

[00:00:13]Passengers [music] carried their own luggage across the tarmac and climbed metal staircases to board the aircraft.

[00:00:18]But that entire system completely broke down once modern jet airliners arrived.

[00:00:23]Take the [music] Airbus A380 for example. Its main upper deck doors sit nearly 26 feet above the ground. Most elderly passengers would struggle to climb that safely. Because as airplanes became larger, safely boarding thousands of passengers every day became a massive challenge. [music] So airports had to completely redesign the boarding process, and that's when jet bridges were invented. Thanks to them, [music] passengers can walk directly from the terminal into the airplane. No stairs, no wind, no rain, and no ice. Even wheelchairs can roll directly on board.

[00:00:52]But the most interesting part is this.

[00:00:53]The entire multi-ton bridge is controlled by a single operator who has to position it with near perfect precision.
