Pulling out all the stops to make carbon brakes more environmentally friendly

Description

For those onboard a commercial jet, the lowering of the landing gear is a familiar sound signaling the home stretch of the flight. Then comes the sound of wheels on the tarmac, and the reassuring deceleration as the brakes slow the aircraft down from approximately 160 mph at touchdown to less than 20 mph in a matter of seconds so the plane can safely taxi to its gate.
