NATO warplanes fly pre-summit training missions over Czech territory

U.S. and Czech fighter jets have taken part in a joint training exercise over Czech territory as part of preparations for November's NATO summit in Prague. Thursday's exercise was designed to rehearse an aerial response to a possible terrorist attack during the summit. Czech officials said American F-16 fighters and Czech MiG-21 jets had participated in the exercise, which simulated the shooting down of a hijacked airliner and an attack on a nuclear power station. The summit, on November 21 and 22, will bring together heads of state and military leaders from 46 countries.
