On 3 April 1996, a United States Air Force Boeing CT-43A crashed on approach to Dubrovnik, Croatia, while on an official trade mission. The aircraft, a Boeing 737-200 originally built as a T-43A navigational trainer and later converted into a CT-43A executive transport aircraft, was carrying United States Secretary of Commerce Ron Brown and 34 other people, including corporate CEOs. While attempting an instrument approach to Dubrovnik Airport, the airplane crashed into a mountainside. All aboard died in the crash except one initial sole survivor, Shelly Kelly, who died en route to a hospital.
