Not "diggers".. But still got my heart beating. This is a guy called James Kingston who describes himself as an adrenalin junkie, constantly looking for adventure. I call him a nutter, always assuming that this is genuine and there is no photo trickery involved.
He posted this video of his climb to the top of a 315ft (96m) tower crane on a construction site in Southampton's Ocean Village, where he then hangs... with just one hand. I suggest tower crane owners will now need to take greater security measures.
Talking with @TCindex on Twitter James said "I didnt go up there to die. I went up there to live"
