An American Airlines flight from Newark to Dallas was diverted to Pittsburgh due to a bomb threat found written in pink ink on a bathroom door. The flight attendant who discovered the note immediately informed the pilot, leading to the diversion. Upon landing, FBI agents and local law enforcement conducted a thorough search of the aircraft but found no bomb. After a delay of over four hours, the flight was cleared to continue to Dallas where it landed safely. No arrests have been made, and the origin of the note remains unknown.
