Malaysia Airlines Flight 17 was a scheduled passenger flight from Amsterdam to Kuala Lumpur that was shot down by Russian-backed forces with a Buk 9M38 surface-to-air missile on 17 July 2014, while flying over eastern Ukraine. All 283 passengers and 15 crew were killed. Contact with the aircraft, a Boeing 777-200ER, was lost when it was about 50 kilometres (31 mi; 27 nmi) from the Ukraine–Russia border, and wreckage from the aircraft landed near Hrabove in Donetsk Oblast, Ukraine, 40 km (25 mi; 22 nmi) from the border. The shoot-down occurred during the war in Donbas over territory controlled by Russian separatist forces in Ukraine.
The responsibility for investigation was delegated to the Dutch Safety Board (DSB) and the Dutch-led joint investigation team (JIT), which in 2016 reported that the aircraft had been downed by a Buk surface-to-air missile launched from pro-Russian separatist-controlled territory in Ukraine. The JIT found that the Buk originated from the 53rd Anti-Aircraft Missile Brigade of the Russian Federation and had been transported from Russia on the day of the crash, fired from a field in a rebel-controlled area, and that the launch system returned to Russia the following day.
The findings by the DSB and JIT were consistent with earlier claims by American and German intelligence sources and by the Ukrainian government. On the basis of the JIT's conclusions, the governments of the Netherlands and Australia held Russia responsible for the deployment of the Buk installation and began pursuing legal remedies in May 2018. The Russian government denied involvement in the shooting down of the aircraft, and its account of how the aircraft was shot down has varied over time. Coverage in Russian media has also differed from that in other countries, which initially characterised it as separatist forces shooting down a "Ukrainian Air Force An-26 transport plane" before switching to blaming Ukrainian forces for shooting down MH17.
On 17 November 2022, following a trial in absentia in the Netherlands, two Russians and a Ukrainian separatist were found guilty of murdering all 298 people on board flight MH17. The Dutch court also ruled that Russia was in control of the separatist forces fighting in eastern Ukraine at the time.
MH17 was Malaysia Airlines' second aircraft loss during 2014, after the disappearance of Flight 370 four months prior on 8 March. It is also the deadliest aircraft shoot-down incident to date and was the deadliest plane crash of the 2010s.
Flight 17, which was also marketed as KLM Flight 4103 (KL4103) through a codeshare agreement, was operated with a Boeing 777-2H6ER, serial number 28411, registration 9M-MRD. Powered by two Rolls-Royce Trent 892 engines and carrying 280 seats (33 business and 247 economy), the aircraft had recorded more than 76,300 hours in 11,430 cycles before the crash. The aircraft was in an airworthy condition at departure.
The Boeing 777, which entered commercial service on 7 June 1995, has one of the best safety records among commercial aircraft. In June 2014, there were about 1,212 aircraft in service, with 340 more on order.
The incident is the deadliest airliner shoot-down incident to date. All 283 passengers and 15 crew died. By 19 July, the airline had determined the nationalities of all 298 passengers and crew.
The crew were all Malaysian, while over two-thirds (68%) of the passengers were Dutch. Most of the other passengers were Malaysians and Australians; the remainder were citizens of seven other countries. At least twenty family groups were on the aircraft, and eighty passengers were under the age of 18.
Among the passengers were delegates en route to the 20th International AIDS Conference in Melbourne, including Joep Lange, a former president of the International AIDS Society, which organised the conference. Many initial reports had erroneously indicated that around 100 delegates to the conference were aboard, but this was later revised to six. Also on board were Dutch Senator Willem Witteveen, Australian author Liam Davison, and Malaysian actress Shuba Jay.
The flight crew were captains Wan Amran Wan Hussin (49) and Eugene Choo Jin Leong (44), and first officers Ahmad Hakimi Hanapi (29) and Muhamad Firdaus Abdul Rahim (26). Captain Wan had a total of 13,239 flight hours, including 7,989 in Boeing 777s. Captain Choo had a total of 12,385 flight hours, including 7,303 in Boeing 777s. First Officer Ahmad had a total of 3,190 flight hours, including 227 in Boeing 777s. First Officer Muhamad Firdaus had a total of 4,058 flight hours, including 296 in Boeing 777s.
The armed conflict in Eastern Ukraine led some airlines to avoid eastern Ukrainian airspace in early March 2014 due to safety concerns. In the months prior to 17 July, reports circulated in the media on the presence of weapons, including surface-to-air missiles, in the hands of the rebels that were fighting the Ukrainian government in eastern Ukraine.
On 26 May, a spokesperson of the Ukrainian Armed Forces stated that a surface-to-air missile system that was being used by the rebels near Donetsk airport had been destroyed by a helicopter of the Ukrainian army. On 6 June 2014 The International New York Times reported that surface-to-air missiles had been seized from military bases. On 11 June, the newspaper Argumenty nedeli reported that a Buk-M1 missile launcher had been present in an area under the separatists' control. On 29 June the Russian news agencies reported that insurgents had obtained a Buk missile system after having taken control of Ukrainian military unit A-1402; and the Donetsk People's Republic claimed possession of such a system in a since-deleted tweet.
Such air defence systems cannot reliably identify and avoid civilian aircraft. The Ukrainian authorities declared in the media that this system was not operational. According to the subsequent statement of the Security Service of Ukraine, three Buk missile systems were located on militia-controlled territory at the time that Malaysia Airlines Boeing 777 was shot down. On the night following the downing of MH17, two Buk launcher vehicles, one of which carried three missiles, (out of a normal complement of four), was observed moving into Russia.
Several aircraft from the Ukrainian Air Force were shot down in the months and days preceding the MH17 incident. On 14 June 2014, a Ukrainian Air Force Ilyushin Il-76 military transport was shot down on approach to Luhansk International Airport, with loss of nine crew members and forty troops. On 14 July 2014, a Ukrainian Air Force An-26 transport aircraft flying at 6,500 m (21,300 ft) was shot down. The militia reportedly claimed via social media that a Buk missile launcher, which they had previously seized and made operational, had been used to bring down the aircraft. American officials later said evidence suggested the aircraft had been shot down from Russian territory.
On 16 July, the Ministry of Defence of Ukraine reported that at about 13:00 local time "terrorists" used MANPADs against a Su-25 jet which was performing a flight mission in the ATO zone. According to the report, the jet received minor damage and was forced to make a landing. Later, the Ministry of Defence of Ukraine reported on the second Su-25 that was attacked on the same day at about 19:00 local time near the Ukrainian-Russian border in the area of Amvrosiivka. According to the details reported by Ukraine's RNBO spokesperson Andriy Lysenko, the Ukrainian Su-25 was shot down by an R-27T medium range air-to-air missile fired by a MiG-29 jet from Russian territory while the Su-25 was at an altitude of 8,250 m. The Russian Defence Ministry said that the accusations were false. In response to additional questions by the Dutch Safety Board, the Ukrainian authorities reported that a "provisional investigation" had revealed that the aircraft had been shot down while flying at an altitude of 6,250 m. Ukrainian authorities also thought that the Su-25 could have been shot down with a Pantsir missile system from Russian territory, though they thought this less likely.
