U-2 Pilots Prepare for Extreme Altitude with Pure Oxygen

Pilots of the Lockheed U-2 Dragon Lady undergo a crucial pre-flight routine to prepare for their high-altitude missions. Before taking off, they spend an hour breathing pure oxygen to mitigate the effects of extreme altitude. This precaution is necessary due to the unique physics at play in the U-2's 29,000-foot cabin altitude. The same conditions that can cause problems for scuba divers surfacing too quickly also affect U-2 pilots. By breathing pure oxygen, pilots can better acclimate to the high altitude and perform their critical missions safely. This specialized preparation is a testament to the U-2's remarkable capabilities and the dedication of its pilots.
