During an appearance on “Fox News Live” on Saturday, former CIA operations officer Laura Ballman called the recent mysterious drone sightings “extremely unsettling,” and posited that they may be part of a “classified exercise.”

“Now in terms of who is behind this, you do seeing the statements that have been made by John Kirby, who has said that these objects are not operating illegally,” Ballman told host Eric Shawn.

“Coupled with the several op-eds that have been out there in the last 24 hours about the need to look at our detection systems, [it] makes me think perhaps this is actually a classified exercise to test either evasion technology or detection technology in urban areas.”
