Comprehensive information and links about Kevin Ryan

Kevin Ryan is a former Site Manager from Underwriters Labs (UL). Ryan's claim to fame is his connection to the questions concerning the collapse of the World Trade Center towers on 911. He was a manager at UL at the time the investigation of the causes of collapse of two WTC towers and an adjacent building.

The exact position Ryan held at UL at the time of interest is "Site Manager at UL's water testing business, Environmental Health Laboratories (EHL) in South Bend, Indiana."

UL is a company that does testings of products to certify they meet certain stated standards. Some products such as common power cords, power supply units occasionally have tags indicating they are "UL Listed." This means the products were tested and certified to withstand certain conditions within the specified operating ranges of parameter.

In the WTC towers case, UL was the company that certified the steel used in construction of the two towers. However the company's spokesman Paul M. Baker stated "UL does not certify structural steel, such as the beams, columns and trusses used in World Trade Center,"

Mr. Ryan wrote to Dr. Frank Gayle urging him to clarify his findings on the causes of structure collapse of the towers for the purpose of eliminating confusions about the ability of jet fuel to soften the steel structures in the WTC buildings.

Frank Gayle was, at the time, the Deputy Chief of the Metallurgy Division, Material Science and Engineering Laboratory, at the National Institute of Standards and Technology (NIST). Gayle heads the "NIST and the World Trade Center" project.

Ryan wrote Gayle because a subsequent report from NIST ignores Gayle's initial findings that weak steel is not the contributing factor in the collapse of the towers. Ryan stated: “Your comments suggest that the steel was probably exposed to temperatures of only about 500 °F (250 °C) This temperature is not enough to soften the type of steel used in the WTC towers. Ryan noted to Dr. Gayle that the normal temperature to soften such steel is at 1100 °C.

Ryan copied the letter to David Ray Griffin, author of the New Pearl Harbor, and to Catherine Austin Fitts, who is a member of the 911Truth.org board. This is how his letter became publicized. Ryan admitted that he wrote to Dr. Gayle on his own capacity and not on behalf of his employer, UL.

Subsequently, UL disavowed Ryan's expertise because he was not employed in the Fire Protection Department.

Ryan was fired from UL thereafter.

In a more personal note posted to various Internet sites, Ryan made his argument alternatively using statistics. He reasoned that "the possibility of fireproofing material fell off in just the right places" is one in a thousand, of office furnishings converged to provide fuel for buring at the precise locations is one in a thousand, of three buildings catching fire and collapsing in the same day at one in a million. In statistics, for an event to occur, the odds is the product of all contributing posibilities. This works out to be about one in a trillion. With such odds, it's difficult to contemplate structure failures of the WTC towers by fire.
