As he hit send, Jas glanced at the clock. 3:00 AM. He leaned back and looked at the PDF’s cover page. Jas Tordillo – Machine Design – Fall 2016. He had written it to pass a class. He never imagined that one day, that same PDF would become a tombstone for a corporation’s negligence.

He was no longer a student. He was a forensic failure analyst hired by MagnaCorp Dynamics. A multi-million dollar stamping press had shredded itself last Tuesday, sending a fifty-pound flywheel through a concrete wall. The official report blamed "operator error." But Jas knew better.
