Two people were taken to hospital after being rescued from their crashed car by firefighters in Maidenhead.
A Rover MG had left the road and hit a tree, leaving the car on its side and the roof bent round the tree.
It took about three and a half hours to extract the victims.
Maidenhead Blue Watch manager Steve Hogg said it was a 'very difficult extraction'.
Firefighters had to take the car to pieces to get the man and woman, in their 20's, out.
Both victims were taken to John Radcliffe Hospital in Oxford - one by ambulance and one by air ambulance.
