A former professional pilot has spent more than 100,000 euros and 5 years to build 3 flight simulators in his backyard. 53-year-old Kenneth Mockford has spent his free time to build simulating flights for two Boeing 737 and a Lynx helicopter at his home in Cambridgeshire. But apart from the passion, it seems that the 53-year-old has begun to look at the benefits of this project, as there are also many training pilots practicing with Mockford simulators.
