Eric Scott, 41, an exserviceman with the US Air Force, flew over The Castle, a 10-storey indoor climbing centre in Stoke Newington, using a so-called Rocketbelt. His 152ft-high flight has set the benchmark for such stunts. Other jumps using the Rocketbelt are usually around 50ft, though none has been officially recorded. Mr Scott said: "It's amazing. I'm completely thrilled."
