In the audio, the soothing and rhythmic sound of a vintage light aircraft, identified as G03-13 Proctor, can be heard. As the audio begins, the aircraft is idling, its engine humming steadily, evoking the golden age of aviation. The Proctor's engine reverberates with a nostalgic resonance, reminiscent of classic aircraft. As the audio progresses, the engine's hum gradually diminishes, signaling the aircraft is preparing to come to a halt. The slow, methodical decrease in sound is akin to watching a visual illusion, an optical spectacle of sorts, as the listener is taken on a sensory journey that parallels a plane preparing to cease its operation. The light aircraft's idling and eventual halting is a symphony of mechanical sounds, beautifully encapsulating the vintage charm of classic planes. The soundscape is a testament to the marvel of aviation, a tribute to the era of light aircrafts that forever changed the way we traverse the skies.
