Gatwick airport runway has reopened after drones caused the airport to shut down for more than a day, the BBC has reported.
The airport, the UK’s second busiest, said 837 flights were scheduled but there were delays and cancellations.
Boss Chris Woodroofe said “mitigating measures” from the government and military had given him “confidence to reopen”.
The drone operator is still at large and police said it was possible they were an environmental activist.
Gatwick airport is expected to be “back to normal” by the end of Saturday.
Thousands of passengers – including some attending funerals, honeymoons and Christmas reunions with their families remained stranded.
The airport could not operate while the drones were in flight in case they hit and damaged a plane.
Gatwick said the 837 flights planned for Friday would have more than 130,000 passengers on board.
A total of 155 flights have been cancelled.
Pilots’ union Balpa said it understood detection and tracking equipment had been installed around Gatwick’s perimeter and that if the drones reappear the airport would close again.
