On February 16, 1959, an F-100 Super Sabre fighter jet crashed in Boulder, Colorado, during a routine training mission. The pilot, Captain Thomas R. Jett, was attempting to complete a high-speed maneuver when the aircraft suffered a mechanical failure, causing it to plummet to the ground. The crash resulted in the deaths of Captain Jett and a civilian who was on the ground at the time. The impact of the crash caused widespread property damage and sparked concern over the safety of jet aircraft in populated areas. The incident led to investigations and reviews of military flight protocols, particularly for aircraft operating in or near civilian zones.
