[1][2][3][4][5][6][7] The numbers, each 0.4 kilometres (0.25 mi)[8] high, were created by a group of five[9] skywriting airplanes, and appeared as a dot matrix.
[3] The string of numbers was produced in a large loop 161 kilometres (100 mi)[8] in circumference, at an altitude of approximately 10,000 feet (3,000 m).
[5] The aircraft used were 1979 Grumman AA-5B Tigers, small, single-engined planes provided by the company AirSign Aerial Advertising, based in Williston, FL.
The numbers were produced by spraying natural, burnt-off canola oil,[10] which dissipated, causing no environmental damage.
[13] The 2014 display was part of an ongoing project, directed by artist ISHKY (Ben Davis), and again involved AirSign Aerial Advertising.
