It's a completely understandable news story, it was a very big, public news event just a few weeks ago and the fact that the pilot involved is "up and about" is very newsworthy, and of course very pleasing.
You can call it "trial by media" or you could say it is a pertinent question.
One would hope that he has at least been questioned at great length by the AAIB by now if not the police, all too often in these scenario's the investigators only have eye witness and mobile phone evidence as sadly in many cases the crew perish. In an aircraft with no flight data recorder I would imagine the pilot's testimony would have been a vital priority.
If he hasn't been interviewed then somebody should be asking why?
