The U.S. Air Force is considering moving some jet fighter training missions to Morocco as a way to ease the burden over densely populated West Germany, the Air Force’s European chief said. Gen. William L. Kirk, in an Associated Press interview, staunchly defended the need to continue low-level training missions in Central Europe. The training missions have caused controversy in West Germany because of military jet crashes in the country. Talks with Morocco are at a “very preliminary stage,” Kirk said in his office at the U.S. air base in Ramstein. The base was the site of a fiery crash of an Italian air force stunt team that killed 70 people at an air show in August. Five West Germans and the pilot died in a U.S. military jet crash Dec. 8 in Remscheid.
