Internet users were still seeking answers in posts beneath the online statement before they were swiftly deleted.The ⁠Chaoyang district government’s statement said Liu had long suffered from insomnia and anxiety and his diary repeatedly mentioned ending his life.Obtaining a private pilot licence in China requires a physical medical examination and other appropriate certifications, a pilot qualified to fly in China said, requesting anonymity due to the sensitivity of the incident.Bystanders outside the Citic Tower following the crash.Adek Berry / AFP via Getty ImagesIt remains unclear how the plane was able to enter an area next to a permanent no-fly zone and also cross highly restricted airspace used by commercial jets arriving ‌at and departing from Beijing Capital Airport (0694.HK), one of the city’s two major airports.On the ​afternoon of the incident, Liu “first carried out an accompanied flight and then a ‌solo flight” out of a general aviation airport ⁠in the suburban Pinggu district, authorities said. The flight deviation occurred during the solo ⁠flight.The statement confirmed for the first time the registration number of the plane: B-12PP.Chinese regulations require all flights, including non-airline ‌general aviation, to be approved ​in advance. General aviation operators must submit detailed ‌flight plans to flight-control authorities before 3 p.m. local time (3 a.m. ET) on the day before takeoff. Flying over urban areas is generally prohibited under China’s civil aviation laws.
