This misty morning in 2000 was the last time I saw the Towers

I took this photo when I was 16 lying on my back in the middle of a crowd of commuters, I remember a passing New Yorker laughing at me shaking his head in amusement. Photographed in 1991

To see these photos of the World Trade Centre, destroyed eleven years ago today, that still look so real is like looking at a picture of a dead family member in their prime. Built 1966-73, destroyed in 2001 killing 2,750 people. The tube-frame design allowed open floor plans as the loads were carried via perimeter columns forming a Vierendeel truss. Architect: Minoru Yamasaki Engineer: Worthington, Skilling, Helle & Jackson. New York, USA.
