context_page_description: Aerial advertising is a form of advertising that incorporates the use of flogos, manned aircraft, or drones to create, transport, or display, advertising media. The media can be static, such as a banner, logo, lighted sign or sponsorship branding. It can also be dynamic, such as animated lighted signage, skywriting, or audio.
  Prior to World War II, aviation pioneer Arnold Sidney Butler, the owner and operator of Daniel Webster Airport utilizing his fleet of J3 Cubs, created banner towing and was credited with a number of inventions and aircraft modifications used to pick up and release banners. At the start of World War II, the government took over the airstrip for military training. Afterward, Butler moved his aircraft to Florida and formed Circle-A Aviation where he continued his banner towing business. Still today, many of his aircraft remain in service and can be seen in the skies over Miami and Hollywood, Florida.
  Aerial advertising is effective if a large target audience is gathered near the source of advertising. Balloons, skywriting, and banner towing are usually strategically located.
context_section_description: Banners using standard letters consist of a series of either 5-foot-high or 7 foot-high letters connected together by joints designed for interchangeability. Standard letters have been the predominant form of banner towing for the past decades.
  7-foot letters have the advantage of greater readability over a long distance, but incur a large drag penalty on the towing aircraft. 5-foot letters, on the other hand, trade off some readability for the ability of the towing aircraft to tow longer messages.
  A typical light aircraft is able to tow 25 7-foot letters or 35 5-foot letters.
  
  Advantages of standard letters are readability over a large distance and flexibility. The letters being prefabricated means they can be made into messages with very short notice and can be changed easily after each flight.
