As I watch
this news, I wonder how it is possible for airplane doors to open so easily from the sky.

There were also flight attendants on board, so why didn't they stop him from opening the door?

When an aircraft leaves the
runway and rises above a certain altitude, the door does not open even if the lever is pulled.

Due to the difference between the external atmospheric pressure and the cabin pressure, the pressure on the door at a cruising altitude of 1,2 meters is about 14 tons.

However, the emergency exit of the Asiana airliner that crashed today was opened at an altitude of about 200 meters before landing.

As the pressure difference between the interior and exterior decreased, the passenger, who was believed to be a burly man in his 30s, was able to force the door open.

There were no locks on the emergency doors, as passengers needed to escape quickly in an emergency, such as a fire.

[Asiana Airlines official: It is designed so that anyone who is physically fit can open the door in case of an emergency. In the event of an (emergency) landing, open the emergency exit door and the slide will unfold so that everyone can escape together. It is also questionable that there was no restraint by the
flight attendant while the passenger opened the door without permission.

Asiana Airlines said, "The flight attendant was seated during landing," adding, "The accident aircraft was a small aircraft and the crew seats were on the other side of the plane, not where the door was open, so it was difficult to respond immediately."

The Ministry of Land, Infrastructure, and Transport dispatched supervisors to the site of Daegu Airport to confirm the specific circumstances of the accident and whether there were any problems with the airline's response, and is also investigating the arrested passengers.

According to the Aviation Security Act, tampering with doors, escape hatches, etc., can be punished with imprisonment for up to 10 years.
