7/7 survivor turns Paralympian
When London celebrated winning the Olympics in 2005, no one could have known what the next 24 hours would bring.
The suicide bombings on the 7th July killed 52 people and injured more than 700.
One woman whose life changed forever that day was Martine Wright, who lost both legs - but seven years later she is poised to represent Great Britain in the Paralympics.
