The Pride of Cumbria helicopter has been called to an emergency in the Lake District - a biker has been thrown off her motorcycle, completely shattering her ankle. On the other side of the country, the doctors and paramedics fly to the rescue of pedestrian Luke, who has collided with a motorbike, the force pushing his brace completely through his cheek.The North of England is biker country - twisting single carriageway roads that weave through the hills and valleys attracting bike enthusiasts in their thousands. But while most will get home safely, hundreds are involved in nasty and painful accidents every year, and it's often up to the Great North Air Ambulance to pick up the pieces.
