Once upon a time, there was a curious young boy named Alex. He loved asking questions and learning new things. One day, he became fascinated with airplanes and wanted to know how they fly.

To find answers, Alex decided to visit an airplane engineer. The engineer had a white lab coat, glasses, and a big toolbox.

The engineer explained, 'Airplanes fly because of many things working together. One important part is called wings. They are like big, flat arms that help the airplane stay up in the sky.'

The engineer continued, 'Another important part is the engine. It's like the airplane's heart. It makes loud sounds and helps the airplane go fast.'

Alex asked, 'What happens when an airplane takes off?' The engineer replied, 'Well, the airplane needs to go really fast to take off. The wings create a special force called lift that helps the airplane lift off the ground.'

Alex also wanted to know how airplanes stay on the right track. The engineer explained, 'Airplanes have a tail that keeps them stable. It's like a rudder on a boat. The pilot uses a steering wheel called the control yoke to guide the plane.'

After the engineer's explanations, Alex had learned so much about airplanes! He thanked the engineer for sharing his knowledge and went home, dreaming about flying in an airplane one day.

From that day on, Alex always remembered the engineer's lessons whenever he saw an airplane. He knew that airplanes were amazing machines that could travel high in the sky, all thanks to the hard work of engineers.
