1. There are no credits on the film identifying the creator.~2. The compressed air in the skirt of the ACV filters through cracks in the ice and forms an air pocket under the surface. This lowers the water level and removes support from the ice, causing it to break under the pressure exerted by the ACV. (Dr. Keith Hindley, “A Breakthrough for Canadian Icebreaking,” New Scientist 25 May 1978, pg 502-503)~3. See ISN 13271 for more related footage.
