Around 4 a.m. on May 15, in the 1-year-old South Texas town of Starbase, Jose Luis Bautista, a 25-year-old man from nearby Donna, rode a scissor lift around 50 feet up toward the ceiling of the “Starfactory,” where Elon Musk’s SpaceX makes parts for its Starship rockets. Bautista and other workers with Delta Fabrication and Machine Inc., a contractor out of Daingerfield, needed to replace metal beams supporting the structure of the factory with new ones.
