Delta Airlines Flight 89 was a plane ride that people took. The plane flew from Los Angeles to Shanghai, which is very far away. However, during takeoff, something went wrong with the engine. The engine is a big part of the plane that helps it fly. Sometimes, things go wrong with engines and they don't work as they should.
When the pilots in the cockpit noticed this problem with the engine, they had to quickly decide what to do. They wanted to make sure that everyone on the plane was safe. So, they decided to turn the plane around and come back to the airport where they took off from.
After the plane landed, the people on the plane were all okay. Nobody got hurt. However, some people were probably scared and maybe a little upset that their travel plans got messed up.
The people who work for Delta Airlines are very good at making sure that planes are safe and that everyone on the plane is okay. They are also very good at fixing any problems that happen with the planes so that people can continue taking flights safely.
