What are the credentials of this Robertson character?
So you have one opinion vs. several experts, you're losing ground.
Leslie Earl Robertson (born February 12, 1928) was one of the structural engineers of the World Trade Center in New York and was responsible for the design of the buildings' sway-reduction features. He has since been structural engineer on numerous other projects, including the Shanghai World Financial Center and the Bank of China Tower in Hong Kong.
As an "up-and-coming engineer", Robertson was selected by Worthington, Skilling, Helle, and Jackson (WSHJ) to participate in the design of the World Trade Center Twin Towers (19661971), his first high rise construction
Robertson's firm participated in the development of a database of basic structural information for the towers of the World Trade Center (WTC1 and 2) for NIST and FEMA and to record the undocumented structural changes that had been made to the buildings after construction began.
