How safety engineers test everyday products to destruction

Whenever we buy a new product or use a service, we simply expect it to work as advertised, usually without giving much thought to how it came to being in the first place. However, behind the scenes, every piece of technology we use, be it a toaster, a lawnmower or even the aeroplane we travel in when we head off on our holidays, has gone through a rigorous series of tests to ensure its safety and efficacy. This often-overlooked aspect of our everyday existence is carried out by test engineers.

In this episode we’re joined by tech journalist and author Alex Davies to talk about his latest book, How to Keep a Plane in the Sky – Tales from the Wild, Unseen World of Test Engineering.

He tells us how engineers design the products we rely on to perform well beyond any expected limits of use, how they build in safeguards to account for almost every eventuality and the great lengths they go to to account for human unpredictability.
