The Raytheon Premier (Exec. Jet) has proven it's fuselage to be very successful. A tape laying machine lays the fibre on to a large mandrel shaped like the fuselage. What a great way to build a modern fuselage with someone sitting monitoring a machine. No more labor intensive assembly with aluminum skins held together with thousands of rivets. Stressed skin fuselages have been around for a long time but it's is great to move on and develop a new way to manufacture fuselages.
