United Airlines flight 1681 bound for Newark returned to on October 24 after a flight attendant saw a passenger texting about hijacking the plane. The crew locked down the cockpit, declared an emergency and landed the 737 MAX 8 on Runway 26L about 50 minutes after departure. Law enforcement met the aircraft, and the flight was delayed overnight after the crew timed out, with a replacement service arriving in Newark more than eight hours late.
