SpaceX needed an actuator that would trigger the gimbal action used to steer the upper stage of Falcon 1. Davis had never built a piece of hardware before in his life and naturally went out to find some suppliers who could make an electromechanical actuator for him. He got a quote back for $120,000. “Elon laughed,” Davis said. “He said, ‘That part is no more complicated than a garage door opener. Your budget is five thousand dollars. Go make it work.’” Davis spent nine months building the actuator. At the end of the process, he toiled for three hours writing an e-mail to Musk covering the pros and cons of the device. The e-mail went into gory detail about how Davis had designed the part, why he had made various choices, and what its cost would be. As he pressed send, Davis felt anxiety surge through his body knowing that he’d given his all for almost a year to do something an engineer at another aerospace company would not even attempt. Musk rewarded all of this toil and angst with one of his standard responses. He wrote back, “Ok.” The actuator Davis designed ended up costing $3,900 and flew with Falcon 1 into space. “I put every ounce of intellectual capital I had into that e-mail and one minute later got that simple response,” Davis said. “Everyone in the company was having that same experience. One of my favorite things about Elon is his ability to make enormous decisions very quickly. That is still how it works today.”
