United Airlines 173

In late December 1978, a United Airlines DC-8 carrying 181 passengers crashed outside Portland, Oregon. 8 passengers and 2 crew members died. The NTSB investigation concluded the crew's inability to work together effectively led to fuel exhaustion causing all 4 engines to flame out.

This crash directly led to multiple airline companies adopting Crew Resource Management (CRM) training beginning in 1981.
