based on what we have seen and heard so far (video,photos,eye witness) it would'nt take a rocket scientist to figure out what happened. Thankfully for all involved (public especially) no fatalitys occurred this time. I hope all potential and current pilots can learn from this reckless avoidable incident(roof top landings included). you rarely get a second chance when it all goes wrong.
The negative publicity does nothing for the industrys future, just provides tomorrows fish & chip paper and a bigger stick for the anti-helicopter lobby.
Let's be a bit more professional in our approach before we are scanning the obituarys for names familiar to us all.
