“The objective of this evaluation is to determine the extent to which the DoD has taken actions regarding Unidentified Aerial Phenomena (UAP),” Mr Stone wrote in the letter.
Next month, the Office of the Director of National Intelligence and other agencies are scheduled to deliver unclassified reports on UAPs to Congress.
A source with knowledge of the subject matter says there will be more inquiries announced in the near future on how these encounters were handled in recent years.
Last April, the Pentagon released three short videos of UAPs from infrared cameras that appeared to show flying objects moving quickly. Two of the videos contain service members reacting in awe at how quickly the objects are moving. One voice speculates that it could be a drone.
Four months later, the Pentagon created a task force to better understand “the nature and origins of UAPs,” the Defence Department said in a statement.
“The Department of Defence and the military departments take any incursions by unauthorised aircraft into our training ranges or designated airspace very seriously and examine each report. This includes examinations of incursions that are initially reported as UAP when the observer cannot immediately identify what he or she is observing,” the statement continued.
The task force has included the videos whose authenticity was confirmed last month.
