America's skies are wide open to national security threats, drone expert warns: 'We have no awareness'

DroneUp CEO Tom Walker speaks with Fox News Digital about his Congressional testimony calling for a nationalized database of drone pilots and flights amid changing technology, while warning the country's airspace regulations are unprepared. As drone technology rapidly advances, industry experts are warning Congress about potential airspace lapses creating the next national security threat if left unregulated. In a U.S. House Homeland Security Subcommittee hearing held last week, drone industry experts testified about the looming threats to airspace safety posed by unmanned aircraft systems (UAS). "More than half of all near misses with commercial and general aviation are with drones," Tom Walker, CEO of DroneUp, told Fox News Digital. Drone experts are asking Congress for a centralized database to track flights and pilots in an attempt to fill gaps in airspace regulations.
