A flight departure board displays scheduled flights with time, destination, flight number, gate, and remarks, updating every five seconds. The animation flips each character individually using a CSS keyframe rotation. The app uses vanilla JavaScript with `setInterval` and `setTimeout` to shuffle flight data, generating random letters and numbers for new entries. Rows are populated dynamically via `createElement` and appended to the table body, while the split-flap effect is achieved purely with CSS transforms.
