About 300 passengers were on board a Boeing 777 Air France to Shanghai Sunday night were urgently evacuated to Roissy-Charles de Gaulle airport after a smell of sulfur and a "dense smoke" invaded the cabin , said on Monday from sources.
While the plane was still at a standstill, the 298 passengers were partly borrowed two inflatable slides that were unfolded on the tarmac, stated the company and two airport sources. Two passengers were slightly injured, one elbow, and a passenger is unwell due to smoke, according to Air France.
An investigation is underway to determine the cause of the technical problem. The two airport sources have assumptions as "a technical failure at a turbine" or "an electrical problem in the APU auxiliary engine" that powers the plane landed and when its engine is stopped.
The passengers were accommodated by Air France and had to start Monday on another device.
Sulfur? Maybe someone let off an old fashioned stink bomb?
