A drone factory in Utah is at the epicenter of anti-China fervor

Washington Post - Technology News 

Teal's workers in Salt Lake City assemble their drones by hand, sitting at several long tables in an open workshop. There is no need for conveyor belts or automated production at their current scale. They do have one robot arm in the back, which is used to calibrate each drone's navigation systems. After calibration, they take the drones out to a grassy patch out front to run them through test flights, with the snow-capped Wasatch Mountains in the distance.
