On that October night during his work binge at the Cape, when Musk asked to speak to Dontchev, the engineer had just gotten home after three straight days of work and cracked open a bottle of wine. At first he ignored the unknown number on his phone, but then one of his colleagues called his wife. Tell Kiko to get back to the hangar right away. Musk wants him. “I’m like super tired, half-drunk, haven’t slept in days, so I got in the car, bought a pack of cigarettes to get me going, and made it back to the hangar,” he says. “I worried about getting pulled over for drunk driving, but that seemed less of a risk than ignoring Elon.”
