A national security scandal from the 1960s involved the disappearance of nearly 400 pounds of highly enriched uranium from the Nuclear Materials and Equipment Corporation (NUMEC) in Apollo, Pennsylvania. Investigations by the CIA, AEC, and FBI centered on NUMEC's founder, Zalman Shapiro, who had documented contacts with Israeli intelligence and hosted Mossad agent Rafael Eitan at the plant. In a 1976 meeting, officials like Brent Scowcroft were told the CIA concluded the uranium ended up in Israel's nuclear weapons program, a finding supported by a 1968 environmental sample from Israel.
