Chinese authorities say the 66-year-old pilot who flew a small plane into Beijing’s CITIC Tower on June 26 wrote in a diary about “ending his life,” citing “personal reasons” as the cause of the crash. Multiple outlets report that the Beijing Chaoyang district government’s investigation concluded the incident was linked to the pilot’s mental health and personal circumstances. Reports describe the pilot as having longstanding insomnia and anxiety, living alone, and being divorced, with diary entries containing multiple references to suicide. The crash occurred in Beijing’s Central Business District and involved an aircraft that local accounts describe as a light plane. Authorities say the crash injured 13 people and that the pilot died. Some coverage also notes public questions and concerns that remain among online observers, while the official position emphasizes that the cause was not attributed to external factors but to the pilot’s personal situation. Aviation safety discussions appear in some reporting, but the shared account across sources centers on the authorities’ findings and the diary details.
