The Geico Skytypers use a ground-based, computer-controlled program to produce the skywriting messages. Each sequence of smoke trails is commanded by radio signals to each aircraft at the correct time to form letters 1000 feet tall at 10,000 feet altitude. This process forms letters much faster and at a larger size than the typical skywriting process.
The Geico Skytypers could be seen in the air during the day at EAA AirVenture Oshkosh 2014 forming "EAA" and "GEICO" in large letters along with their airshow performance. The Aero Experience presents their airshow formations and dogfight routine in the following photo essay:
