London 2012: Paralympic medal hopeful tests in wind tunnel

One of Team GB's strongest gold medal hopes at London 2012 is Paralympic wheelchair racer Shelly Woods, who won silver and bronze in Beijing.

Through collaboration between UK Sport and BAE Systems she has had access to a wind-tunnel at Warton in Lancashire, normally reserved for testing the aerodynamics of fighter jets.

The aim is to help improve her racing position and performance.

Shelly Woods spoke to medical correspondent Fergus Walsh.
