the chief problem is that the repeated sensation of drowning as one
repeatedly readjusts to the new breating medium results in permanent
psychological damage. This might not be bad for individuals who remain
within the medium for long periods, as in the undersea environment, but
it has apparently caused significant problems for its use with pilots of
high performance aircraft. Latest word is that research is focusing on a
dramamine-like drug to counteract this effect.
