Don't you love how they said they can't nail down the cause? Which is technically correct. The big cause is the lack of a separator, but this way they
can say they don't know exactly what specific contamination caused it, and deflect the blame.
Great pic. Before reading that article I would have loved the chance to fly one. They always look fun.
What I can't understand is how hard is it to strap a victim I mean volunteer into one seat with a pulse OX meter taped to a finger and a pilot with a
walk around bottle in the other. Take the plane up and see what the readings are on the meter.
They're looking at a contaminant in the bleed air. In cases of hypoxic hypoxia symptoms abate once they switch to emergency oxygen. In these cases,
the symptoms stay after going on backup systems.
This seems to support it being histotoxic hypoxia. A number of the instructors identified the symptoms as histotoxic hypoxia because of the late
recognition and delayed onset. The question now is where is the contaminant entering the system.
