I'm by no means an expert on this subject, but I recall reading

associated with hydrogen-burning aircraft engines. The reasoning was
that the very high temperatures such engines would operate at would
cause atmospheric oxygen and nitrogen to combine chemically. Has this
perhaps turned out not to be a problem or has technology bailed us out
