Imagine sitting at your desk on a quiet Friday afternoon when the world suddenly shakes and the sky turns to glass. For thousands of people in Beijing today, that nightmare became real.

WHAT HAPPENED

A small plane crashed into the China Zun skyscraper today. This is the tallest building in Beijing, standing 108 stories high.

People inside felt the impact and rushed to the stairs. Outside, metal and glass fell onto the busy streets below.

Police have blocked off the area. We do not know yet how many people are hurt.

What the evidence shows

• Building: China Zun (108 stories tall).
• Time: Friday afternoon.
• Location: Central Business District, Beijing.
• Action: Mass evacuations of the tower and nearby streets.
• Cause: Currently under investigation by local officials.

THE BIGGER QUESTION

This crash happened while tensions in the region are very high. People are wondering if this was a tragic mistake or something more.

How does a small plane get so close to the city's most famous landmark without being stopped? This event will likely change how China guards its city skies.

WHAT HAPPENS NOW

The heart of Beijing is at a standstill. Thousands of office workers are waiting to see if they can ever go back inside.

This will likely lead to much tighter rules for planes flying over the city. Security in the business district will remain very high for the next few weeks.

WHAT WE STILL DON'T KNOW

1. How many people were injured or killed in the crash?
2. What kind of plane was it and where did it take off from?
3. Was the pilot trying to land or did they lose control of the aircraft?
