The night before these disgusting acts I was watching the Discovery channel here in the UK. There was an interesting programme on about the world's highest buildings. They had some very proud guy on saying that the World Trade centre was designed to withstand the direct impact of a Boeing 707, the biggest airliner when it was being designed. Whatever anyone tells you about how safe things are, don't believe a word of it; no-one really has a bloody clue! My deepest sympathy goes to everyone affected by this.Ray
