5 curious questions about airplanes

Question 1
Why do they open the window blinds and turn off the light in the cabin before boarding?

This is to ensure order and peace of mind in the event of an emergency. Through the open porthole, it is easier for stewards to navigate the situation overboard, to determine the procedure for evacuating passengers. The interior lights are switched off in case of a night emergency landing to allow the eyes to adapt to the dark.

Question 2
Why is there an ashtray on the plane if you cannot smoke on board?

Some impatient passengers try to sneak a few puffs on the toilet. For this, an ashtray is installed in the toilet compartment, which guarantees that the cigarette is extinguished in the right place and does not create a fire hazard. And the passenger will suffer greatly: the amount of the fine is impressive.

Question 3
For what purpose are there microscopic holes in the windows of the windows?

The portholes are made of three-layer acrylic panels with microscopic openings, the purpose of which is to maintain a balance of pressure in the aircraft cabin. The temperature difference overboard and inside the cabin is large, so there is a risk of cracks.

Question 4
Why is the food served on the plane tasteless?

The answer is very simple and scientists give it: at flight altitude, the air in the cabin becomes very dry and affects the taste buds of a person. The sensations of sweet, salty, and bitter are dulled, so the food seems bland.

Question 5
What are the white streaks in the sky that the plane leaves during the flight?

For those familiar with physics, the answer is obvious. This is a typical analogy with our breathing in the cold, leaving a whitish vapor. In other words, ordinary condensation. The aircraft's fuel burns to form vapor, which, when in contact with the cold air, leaves a white pattern in the sky.
