 Postwar video analysis of presumed interceptions by MIT professor Theodore Postol suggests that no Scud was actually hit; this analysis is contested by Peter D. Zimmerman, who claimed that photographs of the fuselage of downed SCUD missiles in Saudi Arabia demonstrated that the SCUD missiles were fired into Saudi Arabia and were riddled with fragments from the lethality enhancer of Patriot Missiles.On February 25, 1991, an Iraqi Scud hit the barracks in Dhahran, Saudi Arabia, killing 28 soldiers from the U.S. Army's 14th Quartermaster Detachment.A government investigation revealed that the failed intercept at Dhahran had been caused by a software error in the system's handling of timestamps.
