Exponent has been involved in the investigations of many well known incidents including the now debunked report aired on Dateline in 1993 about fires and explosions involving sidesaddle fuel tanks on &lt;a href="Chevrolet%20C/K"&gt;Chevrolet C/K&lt;/a&gt; trucks, the disputed "Consumer Reports" finding on Suzuki roll-over safety, the 2009–2010 Toyota vehicle recalls, the crash of American Airlines Flight 587 among many other aviation accidents, and the Exxon Valdez oil spill. The Federal Emergency Management Agency also hired Exponent to examine the Oklahoma City bombing damage aftermath, specifically the damage to the Alfred P. Murrah Federal Building. NASA hired Exponent in 1986 to determine the causes of the Space Shuttle Challenger disaster.
