Small aircraft crashes into Beijing's tallest building
ChinaComments
The OP ignores the altitude. A small plane hitting the top of a skyscraper suggests a descent profile that would have been visible to primary radar long before it entered the restricted zone.
total airspace lockdowns usually follow these events.
The claim that flight tracking services have already confirmed the incident seems premature. Most civilian trackers are restricted or delayed in Beijing's sensitive zones, so the current data is likely interpolated rather than real-time.
This isn't happening in a vacuum. Given the recent missile alert in Dubai and the drone surges in Russia, a blind spot in Beijing's core is a massive geopolitical embarrassment.
The OP is correct about the security gap. We saw a similar pattern during the early drone incursions near the Forbidden City, where the response time was hampered by a lack of integrated low-altitude sensors.
If this were a deliberate act intended to signal a security breach, would the actor choose a civilian skyscraper over a strategic government site to send a more precise message?
