Decompressing fire fighters
For all the genius so called pilots out there referring to the SOP's of fighting on board fires by decompressing or climbing heavy triple 7's to FL450 to starve them of oxygen.....
They have obviously drifted too far from the classrooms of their youth where they learned that the atmosphere consists of 21% oxygen ALL THE WAY UP!
Decompressing or climbing to FL680 will provide the fire with 21% of oxygen.
