Every year, thousands of UFOs are encountered by civilian and military pilots around the world. Many go unreported. Craig and Sarah scrutinise the phenomenon and take a closer look at an astonishing case that took place in November 2018 off the west coast of Ireland, in which multiple pilots saw bizarre lights through their cockpit windows. Ted Roe, Director of Research at NARCAP (National Aviation Reporting Centre) shares extraordinary insights into the sighting, while an ex-NATO air traffic controller, under the cover of anonymity, acts as a whistle-blower, spilling more secrets of the sky and the shocking lengths that governments are prepared to go to hide the truth.
