Fatal fighter jet crash -18 F/A-18 accident during the suspension pass zehn ten years later

On August 29, 2016, a U.S. military F/A-18 Hornet fighter jet crashed near the Susten Pass in Switzerland, killing its pilot. The incident occurred during a training exercise involving two aircraft departing from the military airfield in Meiringen. Ten years later, the crash remains a pivotal moment in Swiss aviation safety history, prompting extensive reforms and ongoing discussions about risk management in military flight operations. The accident unfolded in poor visibility conditions as the two jets took off with a 15-second interval. The trailing pilot attempted to follow the lead plane using radar, but the communication link failed. A controller at the Meiringen air traffic control station instructed the trailing pilot to climb to an altitude of 10,000 feet, which was deemed too low for safe flight. The controller realized the error too late, as the pilot had already switched to the Zurich-based air traffic control frequency, making further warnings impossible. Just 58 seconds after the last radio contact, the jet struck a rock face approximately 11 meters below the ridge on the western side of the Hinter Tierberg mountain, resulting in the immediate death of the pilot and complete destruction of the aircraft. In March 2025, the responsible air traffic controller was found guilty of negligent homicide in a second-instance court ruling and received a conditional fine. The pilot of the lead aircraft was acquitted. Despite the conviction, Skyguide, the organization managing air traffic control services, continues to employ the controller. According to Skyguide, he has undergone several careful assessments and is currently undergoing retraining as a civilian air traffic controller. The company stated that, based on the court’s findings, the controller did not act intentionally or grossly negligently during the incident. Aviation expert Michael Weinmann of SRF Aviation notes that the crash resulted from a chain of contributing factors rather than a single mistake. He explained that the controller operated with outdated radar systems, while the pilot failed to recognize the unsafe altitude. Additionally, the inability to establish radar communication with his colleague compounded the situation. Weinmann emphasized that if any one of these elements had functioned correctly, the crash might have been prevented. Following the incident, Skyguide implemented several measures aimed at improving procedures and collaboration. These included optimizing the exchange of information between different air traffic control centers, conducting workshops with both air traffic controllers and military pilots to enhance mutual understanding, and revising protocols for handling emergencies when radio communications fail. The Swiss Air Force also responded by implementing numerous changes. Outdated radar and telephone equipment at Meiringen were replaced, and the time gap between takeoffs of two aircraft was extended. The Air Force adjusted emergency procedures to ensure that conflicts could be avoided even if radio communication was delayed or interrupted. New flight profile graphics were introduced for pilots, and departure procedures from Meiringen are regularly and specifically trained. While many lessons have been learned from this tragedy, the possibility of similar incidents remains a concern. This is acknowledged by all military pilots and air traffic controllers, who understand that residual risks are inherent in aviation. The F/A-18 crash in 2016 remains the last fatal accident involving a combat jet in Switzerland. Despite all the improvements made, the industry acknowledges that absolute safety is unattainable.
