The image shows four small airplanes flying in formation in a clear blue sky. The first airplane on the left is yellow with a red cross on the side, the second is red with a white cross on it, the third is yellow and the fourth is red. All four airplanes have the letters "A-1" written on them, indicating that they belong to the Swiss Air Force. The airplanes appear to be in mid-flight, with their wings spread wide and their engines roaring. The sky is clear and the sun is shining brightly, creating a beautiful contrast with the bright colors of the airplanes.
