Let's find out why there's a small hole in every seat on the plane!

Small hole in the plane’s seat
The identity of the small hole in the seat of the airplane is the manual operation switch of the oxygen mask that will save you in an emergency. The reason why the hole is so small is to make it only available in an emergency.

*Why Oxygen Masks Are Required for Air planes
Decreases air pressure at high altitudes. However, the air pressure is maintained through the machine installed on the plane. If there is a problem with the gas, there is a lack of oxygen due to in-flight pressure, which can lead to unconsciousness.

If there is a problem with the plane, you need to get an oxygen mask. It’s an oxygen mask that automatically falls off your head, but if it breaks down, you can get an oxygen mask by poking a small hole in front of your seat with a pointed object.

The oxygen mask is generally 90 minutes long for the length of the cabin, and the guest has oxygen that can be used for 20 minutes.
