Summary  
This document details an interview conducted by staff members of the House Select Committee on Assassinations (HSCA) regarding allegations made by Mr. David F. Christensen concerning the assassination of President John F. Kennedy. The interview, held on 17 November 1978, involved Sergeant Nicholas B. Stevenson, USAF, who had served at USA-55 in Kirkwood, Scotland, in 1963. Stevenson confirmed that the Lebon-Tangier link mentioned in Christensen’s letter could have been intercepted by the site but was not assigned as a target. He also stated he had no knowledge of any communications related to JFK’s association with Seventeen, though such an event would likely have been widely known within the station. The interview was conducted under a Memorandum of Understanding between the HSCA and the Department of Defense (DoD), which restricted discussions on classified signals intelligence and prohibited disclosure of sensitive information without prior approval. The DoD retained control over any records or transcripts containing classified material.
