I also had the fortunate experience to work with Charley on the Boeing Anti-Satellite (ASAT) program. He was quite the character, and always found a way to add humor to our daily challenges. I wish you (his surviving family) the very best for this holiday season, and may 2014 bring a ray of sunshine as you go on with your own lives without him. My sincere condolences for your loss. RIP Charley.
