Despite the fact that oxygen delivery systems in military aircraft have been in use for so relatively brief a period, this should not obfuscate the fact that awareness of the need for human beings to breath supplemental oxygen as they rise higher in the atmosphere has been in existence and uniformly acknowledged by physiologists for several hundred years. When one considers that powered flight itself will shortly become 100 years old (2003), the fact that oxygen breathing systems in aircraft have only been in use for about 86 of those years takes on enhanced meaning.

The need for special oxygen breathing systems for military aeronautical operations today is taken for granted as being one of the most critically important areas of aircrew life support concerns. This is a two-part history of that important aspect of modern aerospace technology. Modern spaceflight, let alone high altitude flight in aircraft, would not have been possible without the concurrent development of oxygen breathing systems for pilots and aircrew.
