Really, then how does the system know you landed and not crashed on
approach?

ATC as in approach takes no overt action. The tower controller hits the
land line to approach and says "N12345 is on the ground" end of IFR flight.

He does no such thing. No calls, whatsoever. There's no need to.

Are you saying that a telephone call isn't made or are
you saying that nobody in the tower closes the flight
plan?
