Therac-25: A Software Bug That Killed

In the 1980s, the Therac-25 radiation therapy machine killed and maimed several patients due to a software bug. A race condition in the software allowed for the machine to incorrectly deliver massive overdoses of radiation if data was entered quickly. The incident highlighted the severe consequences of neglecting software testing and process management in safety-critical systems. The lack of robust safety mechanisms proved fatal. This case serves as a stark warning in software engineering, emphasizing the importance of thorough software development processes, rigorous testing, and organizational accountability, especially when dealing with life-or-death situations.
