I just stumbled across this image on the Flight image of the day blog and personally I think it beats anything that David Bailey has ever done (Unfortunately the forum software has cut the image down, if you click on the above link you'll get the full version with extra spectators).
A Google search also brought up this old Telegraph article, it seems that during demonstrations Mr Warren would let journalists hit him in the head with a big bit of wood. I'd love to see the risk assessment on something like that nowadays.
My wings are like a shield of steel.
Very true, you would probably need a thirty page risk assessment guidebook before you could do such a stunt nowadays!!!
