My story happened about 20 years ago at the Bronte ramp.
An older father and son were about to launch there boat and the old man was behind directing the son backwards.
It appeared the son hit the gas instead of the brake because the old van proceed to fly into the water up to the front door!
That wasn't the worst part of it, he managed to run over the old man!!!!
I was way down the road and people ran to help but they had to call an ambulance and a tow truck at the same time!
