So all those people asking why was overdue action taken; ever heard of the comedian Micheal Bentine? Heard what happened to his son after HE took off without booking out? I suggest you do a bit of research then. Any ATSU whatever its status (A/G, FIS or ATC) would tend to at least make 'enquiries' if an aircraft was expected and failed to arrive; the French are real sticklers for this especially with VFR traffic.
