Planes may soon have SELF-HEALING wings: Breakthrough material clots like blood to help surfaces repair themselves

Daily Mail - Science & tech 

Tiny cracks on the wings of aircraft can lead to jets being grounded at a cost of millions of pounds. But British chemists have a solution - a self-healing compound that could enable wings to heal themselves in a similar way to how human skin repairs itself. The compound could also be used to make mobile phone screens that fix themselves and hardy nail polish where chips are automatically repaired. British chemists have created a self-healing compound that could enable wings to heal themselves in a similar way to how human skin repairs itself. The research, carried out at the University of Bristol, is said to have'started on the back of an envelope' as the team looked at ways to prevent tiny cracks from forming in places such as aircraft wings.
