I understand that the AAIB Report will be published tomorrow.
It's been leaked to the press and, as a result, there are news items in today's Telegraph and Daily Mail.
Helicopter safety warnings ignored before London crash - Telegraph
Development hit by helicopter was so big pilots COULDN'T fly through London without getting dangerously close to it | Mail Online
I doubt if the Report will contain any surprises concerning causation but it will be interesting to see what safety recommendations are made - and to read what the professional helicopter pilots here think of them. Too far, just right or not far enough?
There's potential for a good informed discussion. I only hope it won't be spoilt (again) by people who've never held a helicopter licence, either professional or private, but that's probably a triumph of hope over experience.
