A small aircraft about the size of a car crashed into Beijing’s tallest building Friday, in a shocking incident that was met with intense censorship on the Chinese internet.

Airspace over China’s capital is tightly controlled, including for drones and small planes, raising questions about how the aircraft was able to get close to the 109-storey China Zun tower, less than 10 kilometres from Tiananmen Square and the government compound of Zhongnanhai.

In a statement Saturday, the Chaoyang district government said a “single-engine, two-seat light sport aircraft” had collided with the tower at 5:55 p.m. on June 26.

“There was only one person on board, the pilot, who died,” the authorities said, without giving any further details of the possible cause of the crash.

Those injured are receiving medical treatment and an investigation is ongoing into the cause of the incident, the statement added.

The area around the crash was tightly controlled Friday evening, with discussion online limited and no coverage in state media. Roads around the tower were closed and there was a heavy police presence stopping anyone getting close.

Police were reportedly telling passersby not to take photos and to delete any footage of the crash.

Nevertheless, videos that did make it to the non-Chinese internet showed the small plane, similar to those used for training pilots, striking and becoming stuck in the upper floors of the building, damaging two glass panels and sending debris raining down on the street below.

Staff and tenants at China Zun were evacuated from the building as police locked down the area around the crash site, picking up debris and packing it into evidence bags late into the night.

Several ambulances were seen parked near the building. The Chaoyang government statement did not give a number for how many people were injured.

According to tracking service FlightRadar, the plane, tail number B-12PP, typically operates out of a small airfield in Beijing’s eastern suburbs, and appears to be used for training purposes — flight data from earlier in the week shows it repeatedly flying in loops before landing.

Completed in 2018, China Zun is Beijing’s tallest skyscraper, at 528 metres. It was developed by and serves as the headquarters of Citic Group, one of China’s largest state-owned financial conglomerates.

Last month, Beijing introduced new regulations tightly limiting the use of drones in most of the capital, requiring prior approval for all outdoor flights, with most limited to specified areas, such as the northwestern Yanqing district, which has been designated a “low-altitude economy” zone.
