The Geico Skytypers Air Show Team flies six WWII era aircraft, the North American SNJ and the T-6 Texan variant. Both were used as advanced training aircraft to prepare pilots of "The Greatest Generation" for WWII. The team performs a low-level, precision demonstration that features maneuvers and tactics flown by the United States military.
In addition to air show performances, the team "skytypes" giant messages in the sky. Five aircraft fly in a line abreast formation and type dot-matrix style 1,000-foot tall messages that can be seen for 15 miles in any direction.
I've never known an industry that can get into people's blood the way aviation does.
