Thomas Stalcup says in two lawsuits filed in Boston last week that he received inadequate responses to Freedom of Information requests to the Missile Defence Agency and the Naval Special Warfare Command.
Stalcup, a physicist, has challenged the National Transportation Safety Board's determination that the explosion of the aircraft's centre fuel tank caused the New York-to-Paris flight to crash minutes after taking off from New York's Kennedy Airport, killing all 230 people aboard. He is among a group of people who believe the plane was downed by a missile.
Stalcup is also seeking records from the Navy SEALs, which participated in recovery efforts after the plane crashed off Long Island on July 17, 1996. Stalcup has asked for all data, imagery, video, memos or other information on SEAL activities with 160 kilometres of the Long Island coast during July and August 1996.
A spokesman for the Department of Defense declined to comment and referred questions to the Department of Justice, which represents the department in court matters. A spokesperson for DOJ did not immediately return a call seeking comment.
The Naval Special Warfare Command, based in San Diego, California, did not immediately return a call seeking comment. Stalcup co-produced "TWA Flight 800," a documentary that aired last month on the EPIX television channel. He is among a group of people pushing to reopen the investigation into the crash.
