The Antonov An-124 Ruslan (Ukrainian: Антонов Ан-124 Руслан, lit. ‘Ruslan‘; NATO reporting name: Condor) is a large, strategic airlift, four-engined aircraft that was designed in the 1980s by the Antonov design bureau in the Ukrainian SSR, then part of the Soviet Union (USSR). Until the Boeing 747-8F, the An-124 was, for thirty years, the world’s heaviest gross weight production cargo airplane and second heaviest operating cargo aircraft, behind the one-off Antonov An-225 Mriya (a greatly enlarged design based on the An-124). The An-124 remains the largest military transport aircraft in current service. The lead designer of the An-124 (and the An-225) was Viktor Tolmachev

The Boeing 747-8 is a wide-body airliner developed by Boeing Commercial Airplanes, the latest and largest variant of the 747. After introducing the 747-400, Boeing considered larger 747 versions as alternatives to Airbus A3XX. The stretched 747 Advanced was launched as the 747-8 on November 14, 2005, for a market forecast of 300 aircraft. The first 747-8F Freighter performed its maiden flight on February 8, 2010, and the passenger 747-8I Intercontinental followed suit on March 20, 2011. The cargo version was first delivered in October 2011 and the airliner began commercial service in June 2012.
On September 11, 2012, an AirBridgeCargo 747-8F experienced a major engine malfunction that spread a significant amount of metallic debris on the runway. Like in a similar event during pre-flight taxi tests, the low-pressure turbine shaft separated and moved the low-pressure turbine backward braking on surrounding hardware (by design to avoid turbine overspeed). The NTSB issued urgent safety recommendations to the FAA to require ultrasonic scans for midshaft fractures before use of GEnx engines and require repetitive on-wing inspections of the engine to detect cracks.
Antonov State Company is a Soviet, and later is a Ukrainian aircraft manufacturing and services company. Antonov's particular expertise is in the fields of very large aeroplanes and aeroplanes using unprepared runways.
