Damage control
Researchers in Britain are working to develop planes that can repair themselves by modeling them on human skin. That might sound bizarre, but it's actually fairly straightforward: The idea involves using composite materials that secrete resin when a plane wears and tears, creating an epoxy scab that will repair minor damage. (Of course, that's only for the fuselageyou'll still need to change the tires every 5,000 miles or so.)
