== UAP THREATEN FLIGHT SAFETY AND, POSSIBLY, NATIONAL SECURITY ==
UAP pose a hazard to safety of flight and could pose a broader danger if some instances represent sophisticated collection against U.S. military activities by a foreign government or demonstrate a breakthrough aerospace technology by a potential adversary.

=== Ongoing Airspace Concerns ===
When aviators encounter safety hazards, they are required to report these concerns. Depending on the location, volume, and behavior of hazards during incursions on ranges, pilots may cease their tests and/or training and land their aircraft, which has a deterrent effect on reporting.
• The UAPTF has 11 reports of documented instances in which pilots reported near misses with a UAP.

=== Potential National Security Challenges ===
We currently lack data to indicate any UAP are part of a foreign collection program or indicative of a major technological advancement by a potential adversary. We continue to monitor for evidence of such programs given the counter intelligence challenge they would pose, particularly as some UAP have been detected near military facilities or by aircraft carrying the USG’s most advanced sensor systems.
