I just saw a sad post over on ZZakk's Lab. On December 21, Ken suffered a fatal motorcycle accident. I only knew him from the web but will miss our discussions. Ken was an innovator in may things rocketry, most notably in monocopters. He was always working on an new and improved cam-pitch mechanism that would optimize the monocopter's flight during both boost and autorotation. I'll be tagging posts referencing his work with 'ZZakk's Lab' for future reference. Feel free to check them out. RIP, old rocketeer.
I decided to swipe a photo of Ken taken at LDRS-6. Via.
