 FACT: The boat leaves the forebay of the Toronto Power Co., which is  about 1/2 mile above the Falls. By the time they start to scuttle  the boat, they are shown about 300 yards above the Falls, yet still  have time to smash holes in the bottom of the boat. At a current  speed of about 12 knots (as stated by one Niagara Parks Policeman in  the film), they are moving at 440 yards per minute, thus would have  less than 30 seconds before going over the Falls.
