    Astonishing footage shows the nerve-jangling moment two inmates escaped via a helicopter that landed on the roof - and no guards tried to stop them despite it taking six minutes. 
    It was filmed by prison guards in Quebec three years ago and has come to light during the unrelated trial of one of the two escapees, Hells Angels sympathizer Benjamin Hudon-Barbeau.
    Clinging to a rope that was precariously dangling from a helicopter, Hudon-Barbeau and fellow inmate Danny Provencal managed to flee the detention centre.
