It's not surprising in the sense that all most of the media are interested in are audience ratings rather than any altruism for reporting the "facts".
Given that probably a handful of people will be killed on Britain's roads today then why don't they give those "innocents" similar coverage?
I'm not so sure that they don't get covered, like this from last month for example:-
M1 Crash: The '140mph death race' that killed two | Mail Online
Given some of the other utter guff published in newspapers a helicopter crashing from the sky in central London was always going to grab attention.
That said I'm not all that sure what is in the media that gets people steamed up. Maybe there are some elements of detail that are not relevant but look someone died on the pavement doing nothing more than going about their daily business 25 mins after a pilot lifted and then called for a weather divert. How much do you think that family cares about the minutiae of aviation procedures?
