No Flying Symbol - Prohibition Icon for Aviation Restrictions #1219873 (License: Personal Use)

The image features a stark white paper airplane diagonally crossed by a thick red prohibition circle and slash, set against a black background for maximum contrast. Its high-visibility design ensures immediate recognition, commonly used in educational, institutional, or regulatory contexts to enforce no-flight zones. The simplicity and universality of the symbol make it effective across language barriers.

Used on school hallway signs, airport restricted-area notices, museum exhibit warnings, or digital policy pages where unauthorized flight (e.g., drones, paper planes) must be discouraged. Matches user intent for understanding safety rules or compliance requirements.
