I've never been on an airplane. What's it like to fly and take off? The feeling of flying? What's it like to fly down?

I have been flying in the sky for many years, flying more than 100 thousand kilometers. My feeling of flying is that when taking off, as the plane climbs, the eardrum of my ear will feel a slight tenderness. This is why the air pressure changes. At this time, just swallow saliva. The oppressive feeling in the ears will be relieved. In the process of flying, under normal circumstances, the flight of the plane is relatively stable, and there will be no uncomfortable feeling. But if there is airflow in the air, the plane will also rise and fall, just like bumping in the waves, and it feels very uncomfortable. All meals on the plane are provided free of charge. Among them, drink as much as you want. Catering can only serve one person. On long-haul flights, the seats in economy class are narrow and difficult. People can't stretch their legs. It will be uncomfortable after a long time. After the plane arrived at its destination. Usually you have to wait on the ground for five to ten minutes. After the plane stops, you can get off the plane in order. In a word, traveling by air is faster. Fly from China to the United States. Only eleven to fifteen hours. These feelings of flying. You can also experience it yourself if you have the opportunity.
