I only knew Charlie for a little over 3 years in my tenure at the FAA, but I always had wonderful interactions with him. It was always fun to spend an hour talking with him or Anton both, about all the projects and how to juggle them. Charlie's personality lit up a room. He was easy to talk to, passionate about what he did, and had an infectious laugh which brought joy in his office. One or twice, I had a meeting with him and Charlie Peppers in a "meeting of the Charlies." I and several coworkers were shocked to hear of his passing earlier this week. I regret not being able to say goodbye one last time, but I look forward to saying hello again someday! God Bless you and your family, Charlie!
