An extract from the PM article posted some time ago .....
At 1h51m, the cockpit becomes illuminated by a strange electrical phenomenon. The co-pilot in the right-hand seat, an inexperienced 32-year-old named Pierre-Cédric Bonin, asks, "What's that?" The captain, Marc Dubois, a veteran with more than 11,000 hours of flight time, tells him it is St. Elmo's fire, a phenomenon often found with thunderstorms at these latitudes.
Amazing Bonin question about St Elmo fire
In any case from a commercial pilot
No need to have a university education or be a veteran pilot to know what is a St Helmo fire
I wonder more and more questions about the knowledge of Mr Bonin
