A United Airlines flight going to New Jersey returned to Las Vegas following an apparent hijacking threat Saturday, according to New York Post. After the flight attendant spotted a passenger texting about hijacking the aircraft, it prompted the crew to secure the cockpit and alert air traffic control. The report states that United Flight 1681 was carrying 150 passengers and six crew members from Harry Reid International Airport to Newark Liberty International Airport. The incident happened on October 24 when a flight attendant noticed a traveller sending messages with reference to taking control of the plane.
