I saw a plane standing motionless in the air. Can the plane stay in the air?

Fixed-wing aircraft is generally impossible, but Britain once produced a fighter called Harrier, which can take off and land vertically and stay in the air for a short time.

When the pressure on the upper surface of the wing decreases, the pressure on the lower surface of the wing increases, and the air flows through the wing section before and after generating an upward pressure difference, which makes the aircraft generate upward lift. With the continuous acceleration of fluid velocity, the upward lift of aircraft is increasing. The plane slowly flew from the ground to the sky after exceeding its own gravity.

In fact, normal flight can ensure the basic safety of passengers in extreme weather (such as turbulence and thunderstorm), no matter where they sit. If the plane unfortunately breaks down and causes a forced landing, is the safety risk the same when sitting in different positions of the plane?

On the surface, it is impossible for the plane to land in all parts of the body at the same time. It must touch the ground at a certain point (such as the front end of the fuselage), so the safety risks of passengers sitting in different positions are definitely different. The distribution of safety factor derived from this also has some truth.

However, other factors can not be ignored. For example, when the plane makes an emergency landing, the landing environment, timing and fuselage angle are often unpredictable, so the results are very different. Is it better to sit in front of or behind your body or in the middle at this time? It's hard to say.
