Following a distinguished career in the Army Air Forces he became the second Director of Central Intelligence in 1946, a position he held until May 1947. In August 1948, when a top secret “Estimate of the Situation” by ATIC offered its opinion that UFOs were interplanetary, Vandenberg, Air Force Chief of Staff at the time, ordered the document to be burned. Despite various attempts by researchers under the FOIA, this “Estimate” has never been traced.
