United Airlines flight makes emergency return to Newark over Bluetooth threat

A United Airlines flight bound for Spain was forced to make an emergency return to Newark, New Jersey, after a potential security threat emerged mid-flight. The incident unfolded on Saturday, May 30, 2026, aboard flight UA236, a Boeing 767 carrying 190 passengers and 12 crew members.

Approximately 90 minutes after departing Newark Liberty International Airport for Palma de Mallorca, the aircraft changed course over the Atlantic Ocean. Air traffic control recordings and passenger accounts suggest the alarm was raised when an active Bluetooth device was detected. This device had been renamed with a four-letter word identified as 'BOMB'.

Despite repeated announcements urging passengers to turn off all Bluetooth devices, at least two remained active. Following instructions from the airline's Chicago headquarters, the pilots declared an emergency, squawking code 7700, and initiated the return to Newark. Upon landing, the plane was held on the tarmac while authorities conducted a thorough search for explosives.

Passengers were evacuated, carrying only their passports and mobile phones, and underwent further security screening by the TSA and CBP. Although United Airlines did not provide official details, the passengers eventually departed on a replacement aircraft in the early hours of Sunday, arriving in Spain later that day. The incident caused significant disruption and anxiety for those on board.
