L. Brown
Major, Aircraft Commander
Major L. Brown served as the aircraft commander of the United States Air Force RB-47H Stratojet during the electronic intelligence encounter of July 17, 1957. Responsible for the operation of the aircraft and its six-man crew, Brown became one of the principal witnesses to an incident involving airborne electronic intelligence equipment, visual observations, and independent ground radar tracking.
During the training mission, Brown was informed by the aircraft's Electronic Warfare Officers that the RB-47's monitoring equipment had detected an unidentified radar emission that did not correspond to known radar systems. As the flight progressed across Mississippi, Louisiana, Texas, and Oklahoma, Brown and other crew members observed a brilliant bluish-white light maneuvering in apparent coordination with the electronic detections.
Ground radar facilities also reported tracking an unidentified target corresponding with the aircraft's position. According to mission reports, the object repeatedly changed course, accelerated rapidly, and on several occasions appeared to anticipate the RB-47's movements before disappearing and later reappearing ahead of the aircraft.
Following completion of the mission, Brown participated in the official Air Force debriefing and the subsequent Project Blue Book investigation. His testimony helped establish the chronology of one of the longest and best-documented military UAP encounters of the 1950s.
The RB-47 encounter continues to be regarded as one of the strongest military UAP cases because multiple independent systemsâincluding airborne electronic intelligence receivers, visual observers, and ground radar installationsârecorded anomalous activity over an extended period. As aircraft commander, Brown's observations remain an important part of the historical record.
