Meet the plane-mad dad-of-two who has built a Boeing 737 flight simulator - in his DINING ROOM. David Naylor, 41, constructed the full size replica of a Boeing cockpit in his home for £15,000 using YouTube video tutorials and material bought off the internet. Incredibly the ex-catering company manager had no electrical or engineering experience before building the ten-foot-wide cockpit which takes up the entire room. Now he can pilot a 737 - an aircraft used by many airlines - with computer generated images on an enormous 4K screen mimicking the pilot's view and the plane's movements. David's simulator contains exactly the same seats, controls and dials that would be found inside the real thing.
