Rotorspeed,
To be honest with you I don't know. And in truth I don't think anyone really truly will.
I knew Max for about 5 years, and I just don't believe that cloud would have been the cause of his death. In my opinion he was a very experienced, capable pilot, and I have trusted him with my life on many occasion.
Max and I (and others no doubt) have known helicopter pilots and passengers who have been killed through getting disorientated in cloud, and as such I for sure have a healthy respect for cloud, and fully appreciate how it can turn out.
I don't think this should turn into a debate about flying into cloud, this is just my opinion and the founding of it.
Regards
Helieng
