Minor correction, but the 777 is not the Dreamliner. The 787 is the Dreamliner. Would be sort of an insignificant distinction except that the fuselage and wings of the 787 are made out of carbon fiber and other composites, whereas the more traditional 777 fuselage and wings are aluminum.
Thank-you for the interesting clarification; much appreciated.
It must be fun flying either one of those aircraft.
