Polish Air Force Flight PLF 101 was travelling from Warsaw to Smolensk to attend a ceremony marking the 70th anniversary of the Katyn massacre. Approaching Smolensk North Airport in dense fog with visibility reduced to approximately 400 metres, the flight crew failed to conduct the approach safely, descending far below the normal glide path until the aircraft struck trees.
On 10 April 2010, the Tupolev Tu-154 struck trees on approach, rolled, inverted, and crashed into a wooded area near Smolensk North Airport. All 96 people aboard were killed, including Polish President Lech Kaczyński, senior military officers, government officials, clergy, and relatives of Katyn massacre victims. Both Russian and Polish official investigations found no technical faults and attributed the crash to crew error.
The disaster prompted the disbanding of the Air Force unit involved and the resignation of several high-ranking Polish military figures. It sparked enduring political controversy in Poland, with the Law and Justice party promoting conspiracy theories of Russian assassination. A 2022 reinvestigation alleging a Russian plot was later found to involve tampered evidence and was revoked in December 2023.
