This is also a safety feature. If the aircraft windows were square, pressure would accumulate in the corners, possibly leading to damage. With round windows, the load is distributed evenly and doesn’t collect anywhere in particular.
19) Why do landing gear tires not burst when landing?
The tires are designed for a load of 4-5 times more than they experience during landing. The wheel will break sooner than its tire bursts.
20) Why do they dim the lights in the cabin?
Passengers should get used to the darkness in case of an emergency landing at night. The lights are turned off so that they can easily navigate when leaving. For a similar reason, you are always asked to open the window shades — so that the flight attendants can see what’s happening outside and choose the best side for the evacuation.
21) Why do airplane pilots always eat different foods before a flight?
This is necessary so that if one of them gets a food poisoning, the other could continue the flight safely.
22) What is the dirtiest place in the cabin?
Nope, it’s not the bathroom. It’s the tray table from which you eat. It has several times more bacteria than the toilet seat. Also, some passengers use this table to change diapers for their babies.
23) Why is food not very tasty on the plane?
This is not because the cook is lazy. The fact is that your taste buds change a little at high altitude. They become less sensitive to flavors.
24) Is it true that hair and stubble grow faster on an airplane?
No, this is not proven by scientists. The myth originated in the first half of the twentieth century. Soldiers noticed that their stubble had grown after the flight, hence the legend appeared. As for the airplanes themselves, the hair on the aircraft will grow at the normal rate.
