My name is Meggan Anderson. I first heard about the story of Frank Stites when I was first cast in Universal Studios Hollywood's Halloween Horror Nights in 2014. I have performed in that show every year since (except the plauge year). 

The story of Frank Stites is known to the performers of Terror Tram; the place on the backlot where the giggling was first heard (believed to be Stites). Stites crashed his aeroplane over the present-day Sign Shop on the Universal backlot. The story of his death is told to the cast every Halloween by our Creative Director, John Murdy, who heard the first giggling.  Some people have said to have seen a figure walking about the Universal Backlot wearing, "old aviator clothes."
