So how do we make the launch more predictable and safe for everyone? That became my obsession this weekend. After many iterations, I have a usable solution. It requires some refinement but the core idea is pretty solid. To finish it off, I want to add a pressure gauge and a catch to hold the rocket on until mission command is ready to launch. It took six modifications and a 3D printer, but I think that will work as well. Here is the "Mk 1" launcher.
