A United Boeing 787-9, registration N27965 performing flight UA-1122 from Newark,NJ (USA) to Cape Town (South Africa) with 253 people on board, was climbing through about FL325 out of Newark when the crew reported smoke of unknown origin in one of the cabin compartments and decided to return to Newark. The crew advised they needed to dump fuel on the way back. The aircraft landed safely on runway 04R about 30 minutes after stopping the climb, vacated the runway and stopped clear of the runway for about 5 minutes for an inspection by emergency services before continuing to the apron.

The aircraft returned to service about 50 hours after landing.
