William Lenoir has passed away at 71. He was a backup crew member for Skylab, an engineer who worked on the Shuttle and on solar power satellites, and the flight engineer on the first operational Space Shuttle mission. Bill served two stints at the company I work with in my day job, Booz Allen Hamilton, with a timeout to be an Associate Administrator of NASA under Richard Truly. I can't recall that I ever met Bill, but I humbly suggest a rule I think all civilizations should take to heart: Explorers should be honored.
Ad Astra, Bill.
