 Marine cryogenic equipment operators on Marine Corps Air Station Yuma work with the two most vital elements needed for any air station around the world. What we do is we just maintain and actually make oxygen and nitrogen liquid and in a gaseous state. The oxygen is vital to supporting life for the pilot while flying, but landing is a different story, which is why nitrogen is used to fill up the aircraft's tires. You just use regular air when they're that high in the altitude, they could actually possibly, they could be liquid in there, like, say water or anything. You could actually freeze and deteriorate the tires faster, so if there was a land, it ropes to the tires and you'd have to crash. These Marines not only provide nitrogen and oxygen for the aircrafts here, but when deployed, have the capability to aid our allies. I'm Lance Corporal Laura Cardoso, Marine Corps Air Station Yuma.
