London's Gatwick Airport has been closed since 9 p.m. on Wednesday -- bar a brief reprieve of 45 minutes early Thursday morning -- after drones were spotted near the airfield. Aviation expert Jon Parker told CNN he'd "seen nothing on this scale before," in terms of deliberate disruption by a drone to a major UK airport. People wait near the departures gate at Gatwick airport, on Thursday. EasyJet canceled all flights to and from Gatwick airport on Thursday. Gatwick doesn't usually operate overnight, but morning is its busiest time, an airport spokesperson told CNN.
