I hope your not in a position of authority with this obvious bias.
Leave the personal crap out of it. Had this gentleman not been able to turn the HYD back on, he'd very likely have rolled on his back like Mike did. His words. He stated in his incident report and to investigators that he could not control the aircraft with both hands and it continued to roll left. Those are facts, not personal biases.
You ned to remove your EC-coloured glasses and look at the facts in this case. Unfortunately for you, you don't have the facts - all you have is speculation and heresay, and are getting it third hand at best. Several dozen others have looked at the facts, and have come to a different conclusion that you.
Your experiences with belt failures with CHC are irrelevant. There have been a million failures of this stupid belt and the vast majority have been non-events. The belt on this aircraft didn't fail, and it's a damn good thing for those three persons that it didn't, for the reasons I have stated previously. Something has changed, and nobody knows what it is.
