The KB SAT SR-10 is a prototype Russian single-engine jet trainer aircraft, fitted with forward-swept wings. It first flew in 2015, and is being offered to the Russian Air Force and for export.
The Russian design bureau KB SAT (Sovremyenne Aviatsyonne Tekhnologii – Modern Aircraft Technologies) began work on a single-engine jet trainer and sport aircraft, the SR-10, in 2007, displaying a mockup at the MAKS airshow at Zhukovsky in August 2009. The SR-10 is a mid-wing monoplane of all-composite construction, with a wing swept forward at an angle of 10 degrees. The crew of two sit in a tandem cockpit. It is powered by a single turbofan, with a Ivchenko AI-25V fitted in the prototype, but more modern Russian engines, such as the NPO Saturn AL-55 are proposed for production aircraft.
The SR-10 was offered to meet a 2014 requirement for a basic trainer for the Russian Air force, but was rejected in favour of the Yakovlev Yak-152, a proposed turboprop trainer. Despite this setback, KB SAT continued to develop the SR-10, proposing it as an intermediate trainer between the Yak-152 and the Yakovlev Yak-130 advanced trainer and for export. The first prototype SR-10 made its maiden flight on 25 December 2015.

The 1989 Belgian MiG-23 crash involved the crash of an unmanned Soviet MiG-23M “Flogger-B” into a house in Kortrijk, Belgium, on 4 July 1989, killing an 18-year-old man.
The incident started as a routine training flight. Colonel Nikolai Skuridin, the pilot, departed from the Soviet Bagicz Airbase near Kołobrzeg, Poland. During takeoff, the afterburner failed and the engine began losing power. At an altitude of 150 meters and descending, the pilot assumed he had a complete engine failure and ejected without incident. The engine had not failed completely, and the aircraft remained airborne, flying on autopilot in a westerly direction. The unmanned aircraft left Polish airspace, crossing into the airspace of East Germany and then West Germany, where it was intercepted by a pair of U.S. Air Force F-15s of the 32d Tactical Fighter Squadron, of the United States Air Forces Europe, stationed at Soesterberg Air Base in the Netherlands. As the MiG-23 crossed into Dutch airspace the F-15 pilots reported the plane having no pilot, radioing “There is definitely no pilot in the plane” and continuing the intercept into Belgian airspace. The escorting F-15s were instructed to down the plane over the North Sea. As the MiG ran out of fuel, it started a slow turn to the south. The French Air Force put armed Mirage fighters on readiness in case the MiG approached French territory. After flying over 900 km (560 mi) the MiG crashed into a house, killing a Belgian teenager.
