When an airplane is flying, the G-force is applied to the whole airplane and everything in it. The following video clip demonstrated the impact of the G-force well. 1) look the water level in the water bottle during the turn, it remains level with the airplane, and 2) during the loop pull up, ~@2:07, see the guy screaming and his face, which is experiencing a 4G pull. G-force cannot be seen (what we see is only its trace after the fact), but it is soooo real.
Another interesting point here, curious about how you look when you get old? Look your face under 5G, that’s what gravity eventually will do to your face.
