These notes were originally intended as a source of general reference
concerning OXYGEN EQUIPMENT AND ITS USE by members of crews of the B-17
and B-24 heavy bomber. With the advent of the B-29 as a combat bomber,
the section on THE B-29 AT HIGH ALTITUDE (Page ) was added to supply
certain specialized information concerning this ship. Every B-29 crew
member should be familiar with the INTRODUCTION and the section on THE
DEMAND OXYGEN SYSTEM as well as this specialized information. The
subject matter is presented from a PRACTICAL point of view, based upon
actual experiences encountered on altitude missions. Detailed
information on oxygen equipment may be found in the following TECHNICAL
