The CEO and chairman of memory chip maker Micron was killed in a plane crash early Friday near Boise, Idaho.  A Micron company spokesman says Steve Appleton, 51, was piloting the small, experimental, fixed-wing plane that crashed. 

Appleton, a professional stunt pilot and former motocross racer, was the only person in the plane when it crashed.  He was known to take part in extreme and thrill-seeking sports.

He started at Micron in the factory in 1983, rising through the ranks to become CEO in 2007.  The company is based in Boise, Idaho and employs 20,000.
