hi my name is Guy. My wife works for an ambulance service in Louisiana where we live. She had an emergency call where a woman and another person had an accident and drove in to a river. The woman called 911 and my wife answered her call. My wife gave her instructions that saved their lives. When I asked her what she told them all she could say was , I remembered the submerging car on mythbusters and remembered what they said. I don't know who will read this or if it will get back to Mr. Adam Savage but I wanted to say thank you. you've saved peoples lives .
