Dr. Jesse Marcel Jr., who said he handled debris from the 1947 crash of an unidentified flying object near Roswell, N.M., has died at the age of 76. Over the past 35 years, Marcel appeared on TV shows, documentaries and radio shows; was interviewed for magazine articles and books, and traveled the world lecturing about his experiences in Roswell. He was credible. He wasn't lying. He never embellished - only told what he saw," his wife Linda said. Marcel's father was an Air Force intelligence officer and reportedly the first military officer to investigate the wreckage in early July 1947. Marcel said he was 10 when his father brought home some of the debris, woke him up in the middle of the night and said the boy needed to look at it because it was something he would never see again. His father maintained the debris "was not of this Earth," Linda Marcel said. After an initial report that a flying saucer had been recovered on a ranch near Roswell, the military issued a statement saying the debris was from a weather balloon. "They were told to keep it quiet and they did for years and years and years," Linda Marcel said. Interest in the case was revived, however, when physicist and UFO researcher Stanton Friedman spoke with Jesse Marcel Sr. in the late 1970s. Friedman wrote the foreword to Marcel Jr.'s 2007 book The Roswell Legacy, and described him as a courageous man who "set a standard for honesty and decency and telling the truth. His legacy is that he had the courage to speak out when he didn't have to about handling wreckage that his Dad brought home," Friedman said Tuesday. "He could have kept his mouth shut. A lot of people did."
