Le 08 octobre 1981 vers 11:00 du matin, Hannah Mc Roberts se trouve avec son mari et sa fille sur une aire de repos proche de Kelsey Bay, sur la côte Est de l'ile de Vancouver. Durant leur pause ils remarquent un nuage qui passe au dessus d'un pic montagneux et donnant l'impression qu'un volcan en éruption est entrain de cracher un immense jet de vapeur. Ils font donc une photo pour immortaliser cette scène plutôt amusante. On October 8, 1981 at abour 11:00 A.M., Hannah Mc Roberts is with her husband and their daughter on a service area close to Kelsey Bay, on the East coast of the Vancouver Island. During their pause they notice a cloud which passes on the top of a mountainous peak and makes the impression of an erupting volcano in eruption spitting a huge vaporblast. They find the scene rather amusing and worth a picture.
Several days afterwards, when the photographa are developed, they notice on one of the photograph that there is a discoidal object in the sky. Their surprise is big, as they do not remember noticing anything in the sky at the time when they shot the photograph.
They contact David Dodge, director of the of Vancouver planetarium. He examines the picture and remains disturbed by this singular photograph. He contacts a ufologist, David Powell, who analyzes the pictures and cannot find any evidence of tampering.
Richard F. Haines, a retired NASA scientist who became a famous ufologist, gets interested in the Vancouver case. He carries out a thorough analysis of the negative and cannot discover any tampering either. His analysis is inserted in the scientific report of the Sturrock Panel.
