Army Secretary Dan Driscoll told "Face the Nation with Margaret Brennan" that drones and flying IEDs are the "threat of humanity's lifetime" as the calls for regulation on drones grow. "I'm pretty optimistic that we will be able to figure out a solution where we will know what is in the sky at every moment across our country, all at once," he added.
