NEW YORK -- Authorities decided to turn around a Delta flight to Madrid shortly after the plane took off from New York over fears of a terror attack after a federal air marshal noticed suspicious looking wires in a lavatory. A SWAT team entered the aircraft and a bomb squad made its search but no explosive device was found. However, authorities found two drinking straws measuring about an-inch-and-a-half long with wires running through each, but no bomb was connected to them. An investigation was conducted and the authorities involved stated that although they had yet to figure out why the straws and wires were present in the lavatory, it did not appear to have been intended as hoax device. Delta flight 126 returned to the JFK airport in New York at 9:33 p.m. A Port Authority Police SWAT team met the aircraft and performed a precision entry since the pilot had notified authorities that there was a woman on board who may be involved in the terrorist plot. The woman, who seemed to have been sickened during the flight, was detained in an ambulance secured by police. While details remain unclear, it seemed that the call made by the pilot and the fact that the suspicious wires were found by a member of a federal air marshal on board the flight, prompted officials to address the incident as a serious threat. An investigation is ongoing and the passengers and crew were interviewed by authorities, but it was noted that no one is in custody and there is no indication that a crime was committed.
