the West German federal election, the controversy was re-opened when questions were asked about the whereabouts of the "Lockheed documents" within the Federal Ministry of Defence. Anonymous sources also distributed several, possibly falsified, documents to the media. According to one of these documents, member of the German Bundestag and its defense council Manfred Wörner accepted an invitation by Lockheed to visit their aircraft plants in the U.S. with the entire trip being paid by Lockheed. In the course of the investigations, it emerged that most of the documents related to the Starfighter purchase had been destroyed in 1962. The whereabouts of the documents were again discussed in a committee of inquiry meeting of the Bundestag between January 1978 and May 1979. An investigation of Lockheed documents by the U.S. revealed that Wörner's trip had been financed by the German Bundestag, and was related to a test flight with the Lockheed S-3 Viking. Only part of the travel costs of Wörner's secretary, and Wörner's flight back from the US to Germany was paid by Lockheed: Wörner was accompanied by his secretary and a portion of her expenses were paid by Lockheed. Further, Wörner "lost" his government paid ticket back to Germany and Lockheed "accommodated" him by giving him another ticket.

Japan The scandal involved the Marubeni Corporation and several high-ranking members of Japanese political, business, and underworld circles, including Finance Minister Eisaku Satō and the JASDF Chief of Staff Minoru Genda. In 1957, the Japanese Air Self-Defense Force wished to buy the Grumman F11F-1F Super Tiger to replace the F-86 Sabre then in service, but heavy lobbying by Lockheed of key Liberal Democratic Party figures led to the adoption of the F-104 instead. Later, Lockheed hired underworld figure Yoshio Kodama as a consultant in order to influence Japanese parastatal airlines, including All Nippon Airways (ANA), to buy the Lockheed L-1011 TriStar instead of the McDonnell Douglas DC-10. On February 6, 1976, the vice-chairman of Lockheed told the Senate subcommittee that
