Flightradar24 has published a message from a pilot from Austria who, on his route, displayed the phrase “Stay home”.

He did this to encourage people to give up traveling because of the spread of the virus. On the Diamond DA40 Diamond Star, the pilot departed Wiener Neustadt and landed in Graz. It took him 24 minutes all the way. You can see how the aircraft prints the letters at this link (https://www.flightradar24.com/data/aircraft/oevds/#24333c62).

A few days later, in the skies above Sydney, Australia, an unknown pilot also “drew” in the sky one of the most important WHO recommendations for the prevention of coronavirus: “Wash your hands.”
