Did he intentionally switch to the stage, having run out his bottom mix?  If
this
is a manifolded system, everything working, then we can conclude this.  Or did
his
rig fail, with catastrophic loss of bottom mix.

Somehow I missed the discussion of lines and getting lost.  How do we know he
got
lost?

Any info from the ME yet?  Drowning vs. MI?  Can oxtox be determined by autopsy?

If he did switch intentionally to the stages, then getting lost and running out
of
bottom mix seems like the main cause of death.  Was he on the 36% stage or the
O2
stage?

Of course, at 240 fsw even on the 36% he gets a ppO2 of (approx) 3 ATA.  But if
he
was on the O2, with 36% available, then we should blame tank identification as a
factor.
