William Boeing Jr., son of company's founder and champion of aerospace education, dies at 92

William E. Boeing Jr., the son of aerospace pioneer William Boeing Sr., has died at age 92.

Mike Bush, a spokesman for The Museum of Flight in Seattle, says Boeing died Wednesday night at his home in Seattle. The cause was not immediately known.

Boeing Jr. did not work at his father's company, but he was nevertheless a champion of the industry and of aerospace education. He helped found The Museum of Flight, and Bush said that in 1975 he paid to move Boeing's first factory — a red barn on Seattle's Duwamish River — to King County International Airport, where it is part of the museum.

Boeing Jr. also supported the museum's educational programs for schoolchildren, as well as Seattle Children's Hospital.
