Three American servicemen and an Italian soldier burned during an air show crash in West Germany arrived in Texas Wednesday, officials said. The four were taken off a C-141 cargo plane that landed at Kelly Air Force Base near San Antonio after a flight from West Germany. They were transported to the burn unit at Brooke Army Medical Center, where they were listed in critical condition. The four were Air Force Master Sgt. Stephen Hull, 32, stationed at Kelly Air Force Base; Army 1st Lt. Kim Strader, 30, of Salt Lake City; Army Pfc. Myron Riggs, 24, of Pittsburgh; and Anderea DelaRosa, 33, a sergeant major. The victims were among the hundreds injured Sunday when three Italian jets crashed during an air show at Ramstein Air Force Base, killing 49 people. (See pictures on A2.)
