The U.S. Army deployed the Patriot missile system in Iraq before fixing problems that may have caused it to mistakenly shoot down non-enemy aircraft, weapons experts told CBS news program "60 Minutes" in a segment to be broadcast on Sunday.
Problems, including a computer "glitch", may have caused a U.S. Patriot missile battery to shoot down a British Tornado fighter plane in March and a U.S. F-18 plane in April, killing its pilot, the program will report.
Also in March, a U.S. F-16 pilot was forced to shoot at a Patriot battery after he received a signal that led him to believe he was about to be fired upon.
