Mr. Bykovski is a machinist-welder who worked alone at the tipple machine shop on the hoot-owl or night shift. Mr. Bykovski has a fondness for Sonny, and is always asking about him. After Quentin and Sonny determine that they need to weld a washer or something onto their casement to be their rocket nozzle, Sonny goes to visit Mr. Bykovski in the middle of the night. When Sonny tells his what he needs, Mr. Bykovski teaches him to solder and then when Sonny can't finish offers to do it for him. Mr. Bykovski helps him on several occasions, until a rocket flies near his dad's Coalwood mine office and Homer Sr. sees it and recognizes it as company property. Mr. Bykovski is punished by being reassigned in the mine as a loader on the evening shift. Later he is involved in a mine accident and is the sole miner who loses his life. When Mr. Bykovski dies, Sonny is despondent and gives up building rockets until he speaks to Mrs. Bykovski, as she is leaving town, and she clears him of all guilt for Mr. Bykovski's death, saying they got used to the higher paycheck, that he could of gone back to welding at any time, and says the one thing Sonny can do for Mr. Bykovski is keep making rockets.
