The plane meal is prepared by the ground crew, because it is not safe for the plane to fly at an altitude of 10 thousand meters, and it is impossible to cook by itself like the high-speed rail. Generally speaking, before the plane takes off, the ground crew will handle the food first and store it in the plane. Then, during the operation of the plane, if passengers need it, it will be heated in a microwave oven and sent to passengers.

In fact, the food on the plane is not as good as we thought. Mostly biscuits, cheese or bread. Drinks are generally all kinds of carbonated drinks or red wine, noodles and rice are not realistic, because first of all, these things are very common, so they are not to the taste of plane passengers. On the other hand, these things are only eaten when they need to be heated, so many airlines find it troublesome, so they rarely have such plane meals. As a means of travel, airplanes are generally short-haul, so there is no need to spend too much energy on airplane meals.
