UFOs have repeatedly entered restricted US military airspace, including swarming Navy ships at sea and lingering over Langley Air Force Base for 17 days, according to former Pentagon official Christopher Mellon, who says hundreds of such incidents now occur every year.
Mellon, a veteran intelligence and defence official who served as deputy assistant secretary of defence, has become one of the most prominent advocates for greater transparency on what the US government now calls 'unidentified anomalous phenomena,' or UAP. Speaking on US television and at a public UFO disclosure forum this week, he argued that the scale and persistence of these encounters particularly around strategic bases and warships is not widely understood, even within government, and may point to a mix of adversary surveillance and something far less easily explained.
