A United Airlines flight to Spain returned to Newark after a possible security threat. The flight turned around mid-air. This was due to a Bluetooth device being named a four-letter word. Passengers evacuated and were rescreened. The flight later departed on a replacement aircraft. This is the latest in a series of United Airlines incidents this month.

The FBI and police responded to reports of a security concern with an unruly passenger on the plane, which diverted to Dane County Regional Airport.

The flight to Palma de Mallorca diverted back to Newark late on Saturday. Air traffic audio and social media posts indicate an onboard Bluetooth device raised security concerns.
