Are airplane emergency doors locked during flight?
According to the Federal Aviation Administration, the exit doors are built to only open on the ground. Even if the plane is at a lower altitude, the air pressure would be too much for a person to open an emergency exit mid-flight.

After all, even the most capable passenger can be incapacitated by one drink too many, which could put lives at risk. They also note that it's unwise to sleep in the emergency exit row. Because, well, it's the emergency exit row. Another unwritten no-no: XL fliers.
For 90% of these emergencies, aircraft continue to their destination. For the remaining 10%, however, aircraft divert to an alternative landing site, most frequently for cardiac arrest, cardiac symptoms (e.g., chest pain), obstetric or gynecologic issues, or possible stroke.
Were you to open a plane window, the compressed air inside would rapidly rush out, atmospheric conditions inside and outside the plane would equalize, and everybody would die. Plane windows that roll down would therefore be, in Romney's words, a real problem.
Why do the flight attendants touch the overhead compartment so often? Flight attendants don't just touch the ceiling for fun when they walk; the bottom of the overhead compartment has a scalloped area that provides a better grip when walking down a moving airplane.
When the aircraft is not pressurized, either on the ground or if depressurized during the flight (intentionally or due to an accident), then pilots can open them. On most modern aircraft, the opening procedure is the same. The window is unlatched, and it then slides inwards into the cockpit and opens to the side.
So overall, turning off the lights during takeoff and landing is a necessary measure to improve visibility and safety for pilots, ATC controllers and passengers. It is an important part of the safety protocols that help ensure air travel is as safe as possible.
Pilot and Vietnam War veteran Pete Jordan knows exactly what happens when a pressurized cabin decompresses 30,000 feet in the air at 300 to 600 mph: There's no oxygen, and it gets damn cold in a hurry. An open door would release the cabin's ball of pressure, causing an immediate suction explosion.
The hole helps regulate how much pressure from inside the cabin is exerted on the plane's windows. It ensures that if a plane's window is going to break (heaven help!), the outer pane goes first. Most commercial aircraft window panes have outer, middle and inner panes, all usually made from acrylic.
The dimming of cabin lights only happens when it is dusk, dawn or dark outside the aircraft. This is a safety measure, and is to ensure your eyes are adjusted to the gloom enough to see the floor lights leading you to safety along the aisle in the event of a crash or emergency evacuation.
Typically, the airplane pressurizes to counteract the drop in air pressure at high altitudes. However, oxygen masks provide redundancy. If anything happens to the pressurization system, or the plane experiences any difficulties while in flight, oxygen masks will deploy.
A doctor may not always be seated in the cabin on your flight, but most commercial airlines are aware that in-flight medical emergencies can happen (I've written about one or two such instances myself in my time at USA TODAY). Most carriers contract with on-the-ground experts in emergency medicine at altitude.
The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.
