I'd love to hear the answer straight from him on that one.  I've
personally heard two versions - one is that condensation got on the
screens in front of the O2 sensors, sealing in a small pocket of gas
against the sensor membrane, fooling the system into thinking that the O2
was high, and therefore the solenoid was never triggered.  Meanwhile, he
metabolized off all the O2 in the loop. This is a critical problem that
I've never seen discussed in books or elsewhere.

The other version of the story was that in the EX-19 they tried to protect 
the sensor membranes from mositure with some sort of hydrophobic membrane 
system, and that this led to a significant lag between the loop PO2 and 
the sensor chamber PO2.

Do you think you could ask him what the real situation was?  I'm not 
being an ass - I'm being sincere here.  If it was one of the above, I'm 
not worried because I've got those covered.  If it was something else 
(which I suspect it was), then knowing about it may someday save my life. 
Maybe it had something to do with that new fangled solenoid deal I heard 
they had - maybe it was so quiet that he couldn't hear it.

P.S. Although I admit to being constipated these past few days in the 
wake of a nasty flu I had over the weekend, I somehow don't think that's 
what you meant when you said I was "full of shit".  In the future, could 
you at least give me a clue as to what comments like that are in 
reference to?  I mean, I lie *so* often on this forum, that it would be 
nice to know which one of my lies you "caught" me on. (Translation: don't 
be such a dumb-ass).
