===United Airlines Flight 173===

When the crew of [[United Airlines Flight 173]] was making an approach to [[Portland International Airport]] on the evening of Dec 28, 1978, they experienced a landing gear abnormality. The captain decided to enter a holding pattern so they could troubleshoot the problem. The captain focused on the landing gear problem for an hour, ignoring repeated hints from the first officer and the flight engineer about their dwindling fuel supply, and only realized the situation when the engines began flaming out. The aircraft crash-landed in a suburb of Portland, Oregon, over {{Convert|6|mi|0|spell=in}} short of the runway. Of the 189 people aboard, two crew members and eight passengers died. The [[NTSB]] Air Safety Investigator Alan Diehl wrote in his report:

{{blockquote|Issue an operations bulletin to all air carrier operations inspectors directing them to urge their assigned operators to ensure that their flightcrews are indoctrinated in principles of flightdeck resource management, with particular emphasis on the merits of participative management for captains and assertiveness training for other cockpit crewmembers.
