A former US Homeland Security officer has revealed the strange thing he saw while working at the Mexican-American border - including what he's certain were UFOs.
Newly released video and testimony from a former Customs and Border Patrol (CBP) agent revealed multiple encounters with "aerial objects" appearing to manoeuvre "well beyond the capabilities of a conventional aircraft", the Debrief reports.
The footage has left some veteran pilots scratching their heads and questioning nature of these objects.
