Introduce fees and/or fines for sartimes = less users of the system = less staff required.Which is probably what Dick is aiming for in the first place and also why ASA empire builders never went with it when suggested.
That said sartimes are yesterday's technology born out of necessity before full radio coverage,transponders and epirbs. Just how many backups do you need? In any event if you put in a 3hour sartime and ditch half hour into the flight you will be waiting 2.5hrs before they even start enquiring. Useless to you if bobbing around in the sea.
