That doesn't make sense. Force is not accumulated by people standing on the ground, so your later analogy does not work at all The ground opposes the force produced by gravity, there is no accumulation of anything. Gravity accelerates mass when it is pulling it in motion unless there is an equal and opposite force which is the normal force exerted by the ground (or airplane)
