skywriting

a form of advertising or message display that involves using a small airplane to write words or draw images in the sky using smoke

Skywriting is a form of aerial advertising where messages or images are created in the sky using smoke from an aircraft. The pilot maneuvers the plane in a specific pattern to release smoke, forming letters or shapes that are visible from the ground. Skywriting is often used for special events, promotions, or to deliver short, attention-grabbing messages to large crowds. It is a unique and dramatic way to advertise, taking advantage of open skies to make an impression on a broad audience.
