A video shows one of the drones that led to the closure of one of Britain's largest airports for more than 32 hours, affecting more than 120,000 people on canceled, delayed and diverted flights.
Gatwick Airport, serving London, closed at 21.00. on Wednesday, when airport personnel saw drones over the runway. After the runway was closed, people slept on ground planes on the terminal floor.
The MailOnline News site posted footage of one of the drones hovering over Gatwick during the shutdown:
The Daily Mail, the sister newspaper of MailOnline, posted a picture of the drone on the runway on Friday.
The airport is now open again, and Gatwick received the first international flight to land at 6am on Friday, 32 hours after the runway closed at 9am. On Wednesday.
Gatwick said that sometimes two separate drones were seen, but most of the disruption seemed to stem from a single one shown in the footage.
The police have not found the drones or their operator yet. Chris Woodroofe Gatwick's Chief Operating Officer told the BBC that the airport had taken additional measures to protect the airport if a drone appeared. He did not say what the measures are.
The police have asked the public for information. They have said little about who might be behind it, but they have suggested that an environmental protest is "a possibility."
On Thursday, 110,000 people were booked on flights and 10,000 were hit on Wednesday evenings.

Woodroofe told the BBC he could not comment on whether the police would try to shoot down a drone when it reappeared.
He said Thursday that the police refused to shoot the drones for fear that a stray bullet might hit someone.
On Friday, 700 flights will be flown from Gatwick, Britain's second largest airport, Woodroofe said.
But airlines warned that they would expect a continued interruption, and called passengers to check their websites. Woodroofe also said that the departure of these flights depends on whether there are more sightings of the drone.

Woodroofe described the disruption as "unprecedented" and said governments and tech companies need to work on solutions if this happens again at each airport.
British Transport Minister Chris Grayling told BBC Breakfast on Friday: "This type of incident is unique in the world, disrupting an airport this way."
He said he would meet "quickly" with other UK airports to make sure that this does not happen again and that other airports will be patrolled on Friday to make sure there are no similar incidents.
