Harry Truman
Harry S. Truman (1884–1972) was the 33rd President of the United States, serving from 1945 to 1953. He is referenced in UAP research in connection with two significant events: the alleged formation of the Majestic-12 study group following the 1947 Roswell crash, and his personal response to the 1952 UFOs Over Washington DC radar incidents in which unidentified objects flew over the White House and US Capitol.

1952 Washington DC UFO Incidents
During the summer of 1952, a wave of unidentified radar contacts over Washington DC — tracked on multiple independent radar systems and corroborated by visual witnesses — generated significant alarm within the federal government. According to contemporary accounts, President Truman placed personal calls to Air Force aides to demand an explanation for the objects tracked over restricted airspace above the nation's capital. His personal intervention indicates the incidents were considered a matter of national security concern at the highest levels of the executive branch.
The incidents prompted the CIA to convene the Robertson Panel in January 1953, a scientific advisory committee tasked with recommending how to manage public interest in UFOs. The Robertson Panel's subsequent mandate to suppress public engagement with UAP phenomena is widely identified as the origin of the institutional UFO stigma.
Majestic-12 Controversy
Documents circulating since the 1980s, known as the Majestic-12 documents or MJ-12 papers, purport to show that Truman authorized the formation of a secret panel called "Majestic-12" to manage information about recovered extraterrestrial craft and biological material following the 1947 Roswell incident. These documents remain contested: some researchers treat them as authentic or partially authentic; others argue they are fabrications. The alleged Truman authorization memorandum is a central exhibit in this debate.
National Security Act of 1947 and UFO Legacy Program Foundations
UAP Gerb's investigation into the Manhattan Project 2.0 identifies Truman as one of the two presidents most responsible for establishing the foundational legal and administrative framework of the UFO legacy program. The National Security Act of 1947, signed by Truman, created the National Security Council, the Central Intelligence Agency, the independent US Air Force, and the Research and Development Board — all identified as foundational institutions within the UFO legacy program structure.
According to J. Andrew Kisner — a former New Mexico State Representative who conducted extensive interviews with legacy program firsthand sources in the early 1990s — a classified presidential executive order signed by Truman in July 1948 vested custody of recovered non-human technical vehicles within the Atomic Energy Commission's national laboratories. This alleged 1948 executive order is identified by UAP Gerb as one of several "Presidential Emergency Action Documents" (PEADs) that gave the Manhattan Project 2.0 its operational legal authority, delegating physical custody of recovered craft to Sandia National Laboratories, Los Alamos National Laboratory, Oak Ridge National Laboratory, and similar institutions.
Truman's relationship to the Manhattan Project was unusual: as a senator, he had chaired the Truman Committee reviewing defense programs and had witnessed millions of dollars funneled into a project labeled only "expediting production" with no further description. When he approached Secretary of War Stimson for an explanation, he was told the information was classified to protect national security. Truman was not briefed into the Manhattan Project until he took office as president following FDR's death in 1945.
