I've been mulling over what Joel said above for the last 24 hours.
I think there are several reasons why people haven't felt it right to post comments here as yet. Pat's point about the recovery effort still being underway is an important one. Another is that the loss of a highly respected individual is the sort of event which is perhaps worthy of a more appropriate medium than a trivial internet forum. Some people are maybe hesitating as they find it quite difficult to articulate their feelings anyway. Yet another reason is that relatively few people in the UK actually knew the bloke directly. (In my case I swapped a great number of amicable emails with him in an effort to encourage him to become involved with the CDG, which I felt would have led to mutual benefit; I failed to persuade him - but I really did try to offer the hand of CDG friendship in my own way.)
Sometimes it's better to take time to ponder on such situations before writing something more meaningful later on. As I have a background role in getting the CDG Newsletter published, my own approach will be to work towards getting a properly thought out tribute prepared for a future issue. Even though he wasn't a member he was a very competent practitioner and most CDG members knew of him, even if they never had the chance to become personal friends.
So, Joel, I think your comments above aren't justified; the simple fact is it's not possible to use an internet forum like this as any realistic sort of gauge of just how upset people are. I know I am, as although I never met him in person, I almost felt I knew him and I certainly understand - and very much respect - what made him tick.
The other important thing to do is to learn from what actually went wrong when the facts emerge, so that none of us is faced with a similar problem during our own diving endeavours in the future. I'm 100% certain he would have wanted that to happen.
