That's why it might not inflate (you might not give it a chance, you panicky rascal).How do airplanes provide emergency oxygen?
The need for an emergency oxygen system in aircraft In most commercial jets, if the cabin pressurization is disturbed above an altitude of 14,000 feet, panels containing oxygen masks pop open automatically and multiple oxygen masks drop down above/in front of the passengers' seats.How long does emergency oxygen last on a plane?
Question: How long will supplemental oxygen last after the masks drop in an emergency? Answer: On typical airliners oxygen generators will last 10 to 14 minutes. That is more than enough time to descend to 10,000 feet or the lowest altitude above the terrain.Do airplanes pump oxygen into the cabin?
