KLM filed a complaint over a September incident in which a passenger’s power bank caught fire on a flight to Curaçao. The crew extinguished the fire and the Boeing 777 returned to Schiphol as a precaution after several hours in the air. KLM said the incident may have endangered the safety of the flight, passengers and crew, and that it reports serious passenger breaches of safety rules.

Several reports identified the power bank as belonging to former KLM executive and politician Camiel Eurlings, but KLM did not confirm the passenger’s identity or whether the complaint was against him.
