A plane allegedly dropped human waste mid-flight, covering a 16th birthday party in feces in Levittown, Pennsylvania. Joe Cambray said his stepdaughter's party was ruined when the more than 40 guests were left horrified as human waste suddenly fell from overhead, just minutes after they had cut the birthday cake. Some of it landed on the family's brand new canopy while other bits hit a baby seat. Cambray said a relative used an app on her smartphone to deduce that several airplanes were flying overhead at the moment in question.
