ME-262 with original type engines

When i was a kid growing up my neighbor was an engineer for Martin Marrietta(sp?) outside Baltimore. One day I went over to ask him about mowing his grass and hanging in his office from the ceiling were 2 model airplanes. One was one of those German jets and the other was a big US bomber (can't remember which one). I asked about the planes and he told me that a month from the end of the war he was the radio man in one of those bombers. Suddenly the plane was hit by something and headed down inside Germany. He managed to get out of the wreckage and was hidden in a barn by an old German couple until the end of the war. Later the military pieced together that they had been downed by one of those jets which was so fast that they never saw it...
