Do Jet Fighter Pilots breathe pure oxygen?

Today’s fighter pilots therefore operate in cabins pressurized according to a pressurization schedule,15 they breathe up to 100% oxygen,15 and they wear and use pressure breathing equipment. Even so, pressure breathing did give fighter pilots a tactical altitude advantage and was in use in World War II.
