中国尊 is very close to 中南海. It is a bit surprising to me that this plane was able to fly into such a sensitive area of Beijing. I thought the airspace, especially at low altitude, would be heavily restricted and closely monitored.
There’s no need to exaggerate this incident. 中国尊 isn’t “very close” to 中南海—the aerial distance is 7 km. That aircraft didn’t actually enter a range where it could pose any threat to Zhongnanhai, so we don’t know what would have happened if it had come any closer.
The damage a 600-kg light aircraft could cause is very limited.
IF Xi had been in 中南海, he would likely have received an early warning and been taken to a secure facility, just as Trump would temporarily take shelter into a bunker if a threat appeared near the White House.
Yes, the airspace near Beijing is strictly restricted, but it is not an absolute no-fly zone. For example, police helicopters and other government aircraft are still permitted to enter the city, so shooting down an unidentified aircraft at random could cause even greater trouble. Moreover, strict restrictions do not equate to strict monitor; small, slow-moving targets flying at low altitudes over urban areas are always very difficult to keep under constant track.
That airport is less than 50 km from the building, and the plane could reach it in just 15 minutes—during which time there’s very little it could do. I suspect that following this incident, virtually all flight schools near Beijing will likely be forced to relocate.
