  1. The carbon fiber fuselage requires lighting mesh where as aluminum fuselage planes don't need to have lightening mesh wrapped around them. Boeing’s latest 777 version has an an aluminum alloy fuselage (aluminium-lithium) "which is cheaper than carbon fiber and better than previous aluminum alloys. As a result, Al-Li alloy-intensive aircraft have better fuel efficiency and LOWER MAINTENANCE COSTS!!!" -- see: AI, Aluminium Insider, May 3, 2022. Aluminium-Lithium Alloys Fight Back. It may be carbon fiber airline fuselages are not the future for airliners.

  2. ​ @richyrichk  ~ Rigorous aeronautical engineering consider metal fatigue over the life of the plane. There are DC-3's flying that are 80 years old, the B-52 is over 70 years old.
