Good grief.
The Nanny State has set up camp in private flying.
Radio is not compulsory and he may have turned his off and listened to his iPod, on a glorious day's flying.
His wife was rung and probably scared senseless, for what? Because he decided to take the long way home on such a good day?
D&D involved? Had someone picked up a Mayday and relayed it?
Assuming he wasn't in controlled airspace without permission, the ATC unit need to get a grip and stop reading tabloid stories of pilots plummeting to their deaths.
