A virtual reality system helps mechanics in Boeing Company’s 25-day training course for its 787 Dreamliner lraen to fix all kinds of problems, from broken lights in the cabin to major glitches with flight controls. Using both laptop and desktop computers inside a classroom with huge wall-mounted diagrams, Boeing airline mechanics train on a system that display an interactive Boeing 787 cockpit, as well as a 3-D exterior of the plane. The mechanics ”walk” around the jet by clicking a mouse, open virtual maintenance access panels, and go inside the plane to repair and replace parts(Sanders,2010)
