Helen Presley rescued three people from a burning car. That is how it all
happened. One evening she went out with her friend Jack for a meal in a small quiet
restaurant. They left at 9 pm and Helen offered to take Jack home. They were driving
along when, suddenly, a car drove past them out of control. The car crashed and after
that it burst into flames.First they ran to the burning car. When they got there, they saw
three people trapped inside. The people were screaming and Helen knew they had to
get them out. It was incredibly hot when Helen and her friend managed to open the
doors.
The driver was sitting inside, unconscious. They got him out and then went
back for the other two passengers. Helen had to climb over the front seat s to get to
them. Surprisingly, the passengers were able to walk away from the car. Meanwhile,
some people who were watching from a nearby campsite, called the emergency
service. We came as soon as possible.
The brave woman was standing there in a state of shock when I asked her for her name
and address. She couldn't remember! She says she didn't do anything extraordinary but
our police department presented them with certificate for their bravery!But I think it's
nice feeling to know you've helped to save someone's life!
