Future concepts: Carbon nanotube fluid heals damaged aircraft in flight (w/video)

(Nanowerk News) Scientists and engineers at BAE Systems have lifted the lid on some futuristic technologies that could be incorporated in military and civil aircraft of 2040 or even earlier.
One of the four concepts is a nanotechnology that allows jets to quickly heal themselves from damage sustained in flight.
The technology is a lightweight adhesive fluid inside a pattern of carbon nanotubes from which the aircraft is constructed and is released when damaged to quickly 'set' mid-flight and heal any damage.
This advanced use of materials would create a highly survivable jet, capable of entering even the most dangerous of scenarios to complete vital missions.
