Lots of sources.  Hey, I am on vacation and have no desire to do any
extended debate or counting game.  But let's start with an easy one
for you and Strike:  Tell me how many Trimix fatalities there are in
the last FIVE YEARS, and I many be able tell you how many or perhaps
even which ones you've missed.  :-)

List them!  Start with 2002, and go backwards.  I don't know of many
"deep air" (see below) fatalities in the past 5 years.


We can argue the below MUCH later :-)  because I ain't got time while
I am on vacation.

You may be right there.  But that doesn't count as "deep air" in my
book anyway unless they go below 218 fsw (1.6 ppo2) which is the
traditional limit considered "toxic".  Even DAN sactions the use of
1.6 ppo2 depth for nitrox, as of 2001.
