If I remember the story correctly Glen. Hans "flying BRM" lost it brakes, and the Hay Bales sent it up in the air. After this picture came out, for a few years this was the "Poster Child" for not belting up
Some people thought it was better to be thrown clear. Crazy as that sounds. This photo was also on the back page "PS" of a early Road & Track. Thanks buddy for posting this, Cheers Tom.
