The airplanes flew over the five boroughs of New York City, as well as Long Island and Westchester County, just before noon.
They created giant messages that were as tall as the Empire State Building, spanned 5-10 miles and were visible from in a 15-mile radius.
The intent by the GEICO Skytypers was to lift spirits and create awareness in light of the current global pandemic.
"We can't think of a better way to thank all New Yorkers for their commitment to health and safety, especially those on the front lines," says Larry Arken, squadron commander and team flight lead of the GEICO Skytypers. "We will deliver messages of hope and gratitude to the city during these unprecedented times."
