On behalf of The American Society of Civil Engineers' Committee on Design of Steel Building Structures, I am writing to thank you for the editorial "Office Towers Are Safest Buildings of Them All" (ENR 4/8 p. 48). It is important that a technically sound and nonbiased assessment be made of the response of the World Trade Center Towers to the destructive terrorist attack of Sep. 11. The profession has every reason to believe that the Federal Emergency Management Agency/ASCE report will be such a document.
