Hypoxia: As low pressure means less oxygen in every breath you breathe, the brain receives less oxygen at high altitudes. The physiological results often include cognitive impairment or light-headedness, which can seriously impair a pilot's ability to fly the plane. Pressurized cabins enable pilots...
Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.
You may bring necessary assistive devices or mobility aids, such as personal oxygen concentrators (POC), apnea breathing devices (CPAP), canes or elbow crutches, into the cabin with you in addition to the carry-on baggage allowance included in ...
Shaking, stretching, dancing – any kind of movement helps, according to Andrew Cox, director of training at Joint Dynamics in Hong Kong. He recommends fitting in a high-intensity workout the day you fly, as it pays back with fatigue that will make you more likely to rest well during you...

"Now you understand my world," he told his son. Earl needed an oxygen tank during that trip. He'd been dying slowly for years and regretted that he wouldn't live to see the end of Tiger's journey. His second heart attack happened in Tulsa, Oklahoma, during Tiger's initial y...
It is possible to go as high as 16,000 feet (4,900 meters) without supplemental oxygen, giving the jumper up to 75 seconds of free fall. When the plane is lined up properly over the jump site, the skydivers jump out of the plane. At about 2,500 feet (760 meters), the skydiver...
Without the liquid oxygen, the shuttle weighs a mere 165,000 pounds (74,842 kg). An air-breathing engine requires no onboard oxygen. The X-43A scoops up oxygen as it flies through the atmosphere. In an Earth-to-orbit mission, the vehicle would store extra oxygen onboard, but less ...
