Air France Flight 953, a Boeing 777 with 37 people aboard, was on a short evening journey from Equatorial Guinea to Cameroon on May 2 when it steered off its planned route to avoid thunderstorms.
As the aircraft turned back toward its destination, the city of Douala in Cameroon, it got too close to Mount Cameroon, the highest mountain in the region whose volcano is still active, said the BEA, France's air accident investigation agency.
