Lightning strike risk after Twin Towers fall September 03 2002 at 09:11PM New York - Scientists fear lightning will become more dangerous in lower Manhattan without the World Trade Centre, which absorbed lightning with its 120m antenna, a news report said. The 110-storey twin towers, destroyed by terrorist attacks on September 11 last year, were the tallest buildings in New York City and one tower was topped by a broadcast antenna. Lightning regularly struck the antenna and was discharged to the ground. - Sapa-DPA
