aerial_ads On a hunch (Google), I came across NationalSkyads.com, which happens to be the same aerial advertising company Gawker is hiring to fly a customized reader-generated message over Rush Limbaugh’s weekend wedding in Palm Beach and boy is it cheap. They charge about $500 for the flight and then $20 per character. The plane will do 4-5 revolutions at about 40 mph and with the media certain to cover it, that’s one cost effective PR stunt!
