For someone accustomed to the sounds and vibrations of an aircraft factory, the quiet hum feels nearly imperceptible at first. The industry surrounding you takes place in vignettes, where one person sits in front of an autoclave, another pirouettes fingers around an electrical board, and still another checks the tiniest bits of solder as they line up in place.
And robots join human hands. One twists around an assembly, articulating in Muppet-like motions. Another tests the next assembly by dunking it over and over into a bath—be it electrolyte or another kind of liquid: water. A third traverses the floor taking one basket to another point on the assembly line.
