Why is one not allowed to open windows of airplane when flying in it?
Pressurization only works in an airtight fuselage. 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.

Yes.On most passenger aircraft models, some cockpit windows can be opened. On the Airbus A320, for example, there are two windows that can be opened, one on the captain's side and one on the co-pilot's.
If the airplane's interior is dark while its exterior is bright and sunny, passengers may struggle to quickly exit the airplane during an emergency. Therefore, airlines require passengers to open their window shades during takeoffs and landings to allow for eyesight adjustment.
One of the most believed ones is that touching the plane offers a bit of good luck, like passengers are thanking the plane for its services and asking it to get them to their destination safely.
So up in the air, the aircraft's door is pushed into place by a force far greater than what you and I will ever be able to overcome by muscle force. Therefore, to answer your question, no – the doors can't accidentally be opened in flight.
Now, you must be wondering what happens if someone opens the emergency exit door of a plane, even if by mistake. Well, the person can be put on the no-fly list by the airlines for a specific period for 'unruly' behaviour, and for putting at risk the lives of all passengers on board.
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.
The middle seats are safer than the window or aisle seats, as you might expect, because of the buffer provided by having people on either side, professor Drury said to the Conversation. He noted that sitting next to an exit row can ensure a quick exit if there is an emergency, except in case if there is a fire.
What happens if you flush a toilet's tank in an airplane while sitting on it? Absolutely nothing. Your arse might ache a bit afterwards. Stories about people being sucked through the toilet and flushed out the plane are urban legends.
All aircraft toilet can be locked/unlocked from outside. The doors can also be locked in the open or closed position for bi-fold doors and locked closed for other types.
And a flight attendant goes into the cockpit so that the other pilot isn't alone (a procedure adopted after the Germanwings crash where a pilot committed suicide, locking the other pilot out of the cockpit).
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. If the cabin lights were on, but then went out your eyes would need a while to adjust to the lower light levels.
Explanation: The small black triangles above windows in a cabin are typically called window eyebrow vents or window deflectors. These triangular-shaped vents serve a functional purpose in regulating air circulation inside the cabin.
As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep flying. Power from the engines will translate into speed, if not height.
