I am very shocked to hear this news and am deeply saddened by it. I had worked with Madison on a few projects at work when we were both down in Hawthorne together. He was always very cheerful and incredibly organized and on the ball with projects. I never got super close to him but could tell he was incredibly sharp and a deeply caring person. I would sometimes run into him at the climbing gym and do a few routes as well.
I too transferred up to the Seattle SpaceX office within the last year and was looking forward to reconnecting with Maddy.
My condolences to his family and all others who knew and cared for him.
