Helicopters generally can't fly above 25,000 feet due to a combination of factors, including decreased air density, which affects lift and engine performance. At higher altitudes, the reduced oxygen levels can impair engine function and limit the pilot's ability to breathe without supplemental oxygen. Additionally, rotor efficiency diminishes in thin air, making it challenging for helicopters to maintain stable flight and perform maneuvers effectively.
