US engineer Leslie Robertson, 90, has been subjected to much criticism and blame after the September 11, 2001 attacks because of his failure to design two towers capable of carrying a plane crash.
In 1945, a military plane crashed unintentionally in the Empire State Building in New York, leaving 14 victims and more than $ 1 million in material losses, but the long tower, which is about 380 meters long, remained upright.
But this did not happen with the World Trade Center, which is more than 100 meters tall, although Robertson insisted that the design, structure and construction took into account "the ability to afford a Boeing 707 passenger plane, "But what happened in the September 10 incident could not have been predicted."
In his documentary, "Linning Out," which will be presented Tuesday at the Design and Engineering Festival, architect Eugene Cohn said Robertson lost much of his joy and enthusiasm after 2001, saying he had to defend himself.
"I was the only person who was confident that the building was safe and everyone was happy, but after the events of 2001, I disappeared from the screen for months," Robertson said. "I had nothing to say to people to make them feel better."
"I got a lot of blame and started to blame myself, too. I was treated for psychiatric treatment with the survivors and their families. It was not easy."
The final expert investigation found that Robertson was not the cause of what had happened. The US engineer and his wife are currently working on a Malaysian tower at 644 meters high.
