A Boeing 777-300ER operated by KLM was diverted back to Amsterdam-Schiphol on Thursday after a fire broke out in the Business class cabin. The incident occurred during a flight from Amsterdam to Curaçao, and the fire was caused by an external battery, commonly known as a power bank, which belonged to Camiel Eurlings, the former CEO of KLM. According to the Dutch news website RTL Nieuws, Eurlings was reportedly charging the device, which violates the airline's safety rules that prohibit the use and charging of such batteries during flights. The flight, designated KL735, had departed from Amsterdam and was en route to Curaçao when the fire broke out over the Atlantic Ocean. A passenger interviewed by RTL Nieuws described hearing a loud explosion followed by flames emerging above a seat in the Business class. The cabin crew quickly responded and managed to extinguish the fire. As a precaution, the captain decided to turn the plane around and return to Amsterdam-Schiphol. The Boeing 777 landed safely after more than five hours in the air. KLM did not officially confirm the identity of the passenger involved, but RTL Nieuws reported that multiple witnesses on board confirmed the battery belonged to Camiel Eurlings. A passenger seated near Eurlings said the former CEO was sleeping during the incident and was affected by the fire. She noted that Eurlings felt bad about the situation and the inconvenience caused to others, calling the incident "incredibly stupid." The passenger also pointed out that as a former executive, Eurlings should have been familiar with KLM's safety guidelines. The Boeing 777-300ER carried 322 passengers, and KLM provided hotel accommodations at the airport. Passengers resumed their journey to Curaçao on Friday morning on a different flight. No one was injured, although Eurlings reportedly sustained minor injuries. KLM has launched an investigation into the incident. This is not the first such occurrence for the airline; in the summer of 2025, a similar situation occurred on a flight between São Paulo and Amsterdam, where a power bank emitted smoke and had to be extinguished by the crew. KLM's policy allows passengers to carry up to two external batteries with a maximum capacity of 100 Wh in their carry-on luggage. These devices must be kept visible and accessible and cannot be placed in overhead compartments or checked baggage. The use and charging of these batteries are strictly prohibited during the flight. This rule is in place to reduce the risk of overheating or thermal runaway of lithium-ion batteries, which can be particularly dangerous in an aircraft environment where any fire is a major safety concern.
