A fighter jet among a troubled fleet of F-15s that recently returned to the skies plunged into the ocean, but the pilot ejected in time and was rescued shortly afterward. A Coast Guard helicopter plucked the Hawaii National Guard pilot from the ocean Friday. He was taken to a hospital and was listed in good condition. The pilot had extensive flight experience, said Maj. Gen. Robert G.F. Lee, the Hawaii National Guard commander. "Our first concern was whether the pilot was OK," he said. "I got the chance to visit with him in the hospital. He's terrific." The cause of Friday's crash was being investigated.
