What happens if a plane window opens?

Should a windown somehow be opened in a pressurized aircraft, it would lose cabin pressure requiring a descent to a safe breathing altitude. As long as the person seating next to the window has his/her seatbelt fastened, there should be no danger. It would get cold, windy, noisy and uncomfortable.

Basically, the air pressure inside the cabin is higher than it is outside of the plane to enable the people onboard to breathe normally. That's why, if a window happens to break, the air inside would escape at high speeds, taking small objects like phones or magazines (or sometimes larger things, like people) with it.

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.

A passenger on an Asiana Airlines flight recently opened an emergency door while the flight was in the air—something that shouldn't be able to happen. We looked into it. Usually, when the cabin is pressurized, the exit row doors can't be opened.

Back in the early days of jet travel, there were some pretty bad episodes with windows but even then airplanes did not crash. Goglia says that cockpit windows in particular are very strong, designed to survive everything from bird strikes—as in Sully Sullenberger's “Miracle on the Hudson” flight—to hailstorms.

But many of their advanced functions are only advisory in nature: Pilots still must look out the window to verify what they're telling us.

The cockpit door automatically locks, but a keypad outside allows a flight attendant to insert a security code to gain access. A buzzer sounds, and the pilots must switch the door control inside the cockpit to “unlock” to release the door after verifying the crew member through a peephole or video surveillance.

Some aircraft damage from lightning strikes includes broken lighting and windows, deformed antenna placements, and onboard electronics malfunctions. Other abnormalities or warnings on the flight deck, such as cabin air pressurization problems or false alarms, can occur after your airplane has been struck by lightning.

On the most basic level, the person in the window seat has control over the window shades, and shouldn't need permission from the person in other seats as to how the window shades are kept. The person in the window seat can, within reason, decide if they want the window shade opened or closed during the flight.

Flying is considered very safe due to modern technology, improved aircraft equipment designs, and enhanced pilot, mechanic, and air traffic control training. There are fewer planes in the air than cars and trucks on the road with much more space between them, further leading to safer travel conditions.

“Accidents are rare in aviation. There were five fatal accidents among 32.2 million flights in 2022. That tells us that flying is among the safest activities in which a person can engage. But even though the risk of flying is exceptionally low, it is not risk-free.

In fact, most mid-air collisions take place during the day when the weather is warm and clear. This is because there are more pilots out flying when the weather is ideal and most of them will be relying on VFR (or visual flight rules).

The term hard landing usually implies that the pilot still has total or partial control over the aircraft, as opposed to an uncontrolled descent into terrain (a crash). Hard landings can vary in their consequences, from mild passenger discomfort to vehicle damage, structural failure, injuries, and/or loss of life.
