According to an article in Atlas Obscura entitled:
Some Pilots Are Using Their Flight Paths to Draw in the Sky

From Atlas Obscura:
In general, the sky isn’t a great medium for creativity. Your options are limited to a banner pulled behind a plane, or using special smoke to write giant letters that will get swept away by the wind—maybe before you reach the end of the message. But there’s another way that pilots express themselves, though it’s not immediately apparent to the ground-bound. Using a flight tracking program called CloudAhoy, pilots around the country have been drawing some intricate designs in the sky for a contest to see who can most effectively merge their skills in the air with their creative flair.
The contest, called the Wild Blue Doodle and put on by aviation company Lightspeed, challenged pilots to “create a work of art in the sky” with their flight paths, as tracked by the software, for a chance to win a new headset (worth $850). Pilots around the country took advantage of the chance to show off. The large-scale designs include a sneaker, Snoopy in his “World War I Flying Ace” guise, a howling wolf, and even a self-portrait of sorts—one pilot flew his DA40 plane in the shape of a DA40.
