Titanic Disaster
The largest ocean liner in service at the time, Titanic was four days into her maiden voyage from Southampton to New York City, with an estimated 2,224 people on board when she struck an iceberg at 23:40 (ship's time) on 14 April. Her sinking two hours and forty minutes later at 02:20 ship's time (05:18 GMT) on 15 April resulted in the deaths of more than 1,500 people, making it one of the deadliest peacetime maritime disasters in history

Heinrich's Domino Model of Accident Sequences
Heinrich's Domino Model, developed in 1931, posits that workplace accidents result from a chain of five sequential, interconnected factors (dominoes), where the fall of one triggers the next: ancestry/social environment, personal fault, unsafe act/condition, accident, and injury. Removing any single domino prevents the injury.

Unix Version 4 rewitten in C
The operating system was originally written in PDP-7 assembly language, and ported to PDP-11 assembly language in 1970, but in 1973, Version 4 Unix was rewritten in C. Ken Thompson faced multiple challenges attempting the kernel port due to the evolving state of C, which lacked key features like structures at the time. Version 4 Unix, however, still had much PDP-11 specific code, and was not suitable for porting. The first port to another platform was a port of Version 6, made four years later (1977) at the University of Wollongong for the Interdata 7/32,[followed by a Bell Labs port of Version 7 to the Interdata 8/32 during 1977 and 1978.
