While we all know there's a greater chance of a shark attack than there is of being in a plane crash, we've all seen Lost. It's scarred us all. It's really no surprise aeroplane safety is being so scrutinised now.
Taking inspiration from spider webs, scientists at Stanford University have developed something akin to a netting system of sensors, which is wrapped around the plane. It's incredibly light, and as soon as a fissure, crack or any other form of damage happens to the aircraft, the sensors feed back to a computer for the pilots to act upon.
