From then on, we vented
it down in the neighborhood of between 890 and
93, depending upon who was asleep and who wasn't
asleep. It sure seemed to be an unsatisfactory
solution to two problems--one of the cabin hold­
ing at a higher pressure than they wanted it to
on GT-3 and also the problem of the o system

venting outside of the pressure gage.
In the
oxygen system I think the solution to putting
the venting down at 967 was a poor solution to
the problem of having a poorly designed gage .
I think the gage was agai n poorly designed and
it should be designed to read about 1200 pounds.
Rel ief should be up in that area.
I f they really went ahead and jacked down the
relief pressure, to get it on the gage, I think
that is one heck of an approach to an engineer­
ing problem.
I think that ' s a gross thing to do and if they
did that deliberately, I thi nk they deserve a
