   The bottom doesn't impede anything and, to prove it, in my new animation   
   https://www.geogebra.org/m/mdymaxsb I totally eliminate it.   
      
   Now, the well goes from one part of the Earth to the other.   
      
   Initially, elevator A is constrained near the surface and elevator B is   
   constrained to the center of the earth: neither of the 2 elevators can move.   
      
   If you remove the constraints with the appropriate button, elevator A   
   accelerates in free fall and elevator B remains stopped in its place.   
      
   Question: Is the unconstrained elevator B that stays in its place an inertial   
   or accelerated reference frame?
