Most commercial passenger planes cannot fly at 60,000 feet; they typically cruise between 30,000 and 42,000 feet where the air is thin enough for fuel efficiency but thick enough to provide sufficient lift and oxygen for the engines. Flying significantly higher than 42,000 feet in a standard Boeing or Airbus is dangerous because it approaches the "coffin corner," where the difference between the stall speed and the speed of sound becomes dangerously narrow. However, specialized aircraft definitely can and do fly at 60,000 feet. Historically, the Concorde cruised at this altitude to avoid turbulence and take advantage of the thinner air at supersonic speeds. In 2026, certain military jets (like the F-22 or U-2), high-altitude surveillance drones, and the newer generation of supersonic business jets currently in testing are designed to operate in this "near-space" environment. For standard travelers, the view from 40,000 feet remains the norm, as the engineering required to pressurize and power a massive cabin at 60,000 feet is not yet cost-effective for mass transit.
