A chartered aircraft carrying Wichita State University football team members crashed into Mt. Trelease after departing Denver-Stapleton. The accident killed 32 people and injured eight others.

Incident Overview and Route Details A chartered airplane was operating a special flight for the Wichita State University football team, transporting players and supporters from Wichita to Logan with an intermediate stop in Denver. Following departure from Denver-Stapleton Airport, the flight crew deviated from the intended course and followed an incorrect track. ## Crash Sequence and Casualties While cruising at an altitude of 10,800 feet, the aircraft struck trees and crashed on the slope of Mt. Trelease, a peak with an elevation of 12,447 feet. The crash site was located approximately 10.6 miles west of Silver Plume. The impact and subsequent post-crash fire completely destroyed the aircraft. The accident resulted in the deaths of two crew members and 30 passengers, while eight other occupants sustained serious injuries. ## Official Findings The investigation determined that the probable cause was the intentional operation of the aircraft over a mountain valley route at an altitude that prevented the crew from either climbing over the obstructing terrain ahead or executing a successful course reversal. Significant contributing factors included the overloaded condition of the aircraft, the virtual absence of flight planning for the chosen route from Denver to Logan, a lack of understanding by the crew regarding the aircraft's performance capabilities and limitations, and a lack of operational management to monitor and appropriately control the flight crew's actions.
