3 OXYGEN MASKS

Myth: You need to wear oxygen masks at very high altitudes.

Only on the plane. Hypoxia can set in quickly at 18,000 feet, so it’s necessary for planes to supply it when climbing to that altitude and beyond. The most common high-altitude jumps are between 10,500 and 14,000 feet. Some larger drop zones with larger planes will offer special “extra-high” jumps of 22,000 feet. This of course costs “extra-cash.” Some fancier planes offer masks, but more often it consists of a small hose coming out of the ceiling of the plane and you simply put it in your mouth up until you jump. Once you’re out, you’re only at that altitude for a short time, so extra oxygen on the jump itself isn’t necessary.
