AIRCRAFT ACCIDENT REPORT. WESTERN AIR LINES, INC. BOEING 737-200, N4527W CASPER, WYOMING, MARCH 31, 1975

About 0743 on March 31, 1975, Western Air Lines, Inc., Flight 470, overran the departure end of runway 25 at Natrona County International Airport, Casper, Wyoming. The landing was made following a nonprecision approach on a snow-covered runway, with a following wind, and during reduced visibility. Of the 99 persons aboard the aircraft, 4 were injured. Of these four injuries, three occurred during the evacuation. The National Transportation Safety Board determines that the probable cause of the accident was the failure of the pilot-in-command to exercise good judgment when he failed to execute a missed approach and continued a nonprecision approach to a landing without adequately assessing the aircraft's position relative to the runway threshold.
