The Real Reason Airliners Stay Below 40,000 Feet (Simply Explained)

✈️ Why Don’t Airplanes Fly Higher Than 35,000–40,000 Feet?

Discover the hidden science behind airplane cruising altitude and why commercial aircraft don’t fly at extreme heights like 50,000 or 70,000 feet.

🔍 In This Video, You’ll Learn:

• Why airplanes cruise between 35,000 and 40,000 feet
• How thinner air reduces drag and improves fuel efficiency
• Why jet engines lose performance at higher altitudes
• How wings generate lift—and why thin air makes it harder
• What the “coffin corner” is and why it’s dangerous
• How speed limits shrink at extreme altitudes
• The role of cabin pressurization in passenger safety
• How high altitude increases structural stress on aircraft
• What the “service ceiling” means in aviation
• How step climbs improve fuel efficiency during flight
• Why temperature affects engine performance at altitude
• Why planes avoid both very high and very low altitudes
• The balance between safety, efficiency, and performance
• How commercial jets differ from U-2 and Concorde aircraft
• Why the atmosphere has a “sweet spot” for flight
🧠 What You’ll Understand:

• The physics behind airplane altitude limits
• How lift, thrust, and drag work together
• Why airplanes can’t just keep climbing higher
• How aviation design is optimized for real-world conditions
