[00:00:00]At 35,000 ft, opening an airplane door is almost impossible. Even if a passenger pulls the handle, the door won't open. But why? The answer is [music] cabin pressure.

[00:00:13]Inside the airplane, air pressure pushes against the door with thousands of kilograms [music] of force. And most airplane doors are designed to open inward first before moving outward. That means the pressure seals the door tightly shut during flight. So, no matter how hard someone tries, the sky itself is holding the airplane door closed. That's engineering.
