The pilot also drew two phallic symbols in the sky.
Perth Now reports that the unnamed pilot was running in a new engine by flying at a particular power setting for two hours when he decided to use the sky as his personal canvas. Though his artwork could not be seen from the ground, it was visible to aviation followers watching live flight tracking programs and websites.
FlightAware website captured the pilot's work and his explicit graffiti, and it has since gone viral online.
Here are some of the reactions to the pilot's work:Earlier this week a bored pilot in Australia left this message in the skyhttps://t.co/sE1l5RnXZa pic.twitter.com/9hOwFX6Mb3
