A further drone sighting has again disrupted the UK’s second biggest airport, with flights grounded and passengers unable to fly.
Aircraft were left circling above the area during the latest alert, which came at about 17:10 GMT. Flights resumed less than 90 minutes later.
A spokesman for the airport said the suspension was only as a precaution.
He said military measures had been put in place that meant it was safe to reopen.
Gatwick had reopened earlier on Friday, after drones flying over the airfield closed it for more than a day.
The airport was initially closed on Wednesday at about 21:30, following the first drone sighting.
Police believe more than one unmanned aircraft has been used and are investigating the possibility of multiple culprits.
In a statement, police confirmed operations were suspended for safety reasons.
The force said: “Sussex Police is supporting the airport and is proactively deploying significant resources to seek and locate the drone and its operator and to ensure the safety of the travelling public and all those in and around the airport.”
Passengers have hit out at the people behind the disruption.
One woman, called Poppy Smithers, hoping to fly to Doha and then Auckland, said it was “very disruptive, kind of selfish”.
Newlywed Emily had just arrived at the airport to go on honeymoon in Argentina. She and her husband had expected to fly out at 21:30.
“It’s a little bit heartbreaking, really, because we’ve been looking forward to this for a long time,” she told BBC Radio 5 live.
“It doesn’t sound too promising right now,” she said.
Nikkita Sartori-Sigrist, 24, and Oliver Vaff, 22, from Loughton, Essex, were stranded on the runway on a grounded BA flight to Cologne.
They were due to take off when the captain announced there had been another sighting, they said.
The pair were heading to Cologne to visit the Christmas Market and then fly back on Christmas Eve.
“We’ve been planning it for a really long time and don’t want to miss it but now I’m worried if we go we might not come back,” Ms Sartori-Sigrist said.
During disruption on Thursday, 760 flights had been due to arrive or depart from the airport but all were grounded.
On Friday, 155 flights were cancelled.
Gatwick’s chief operating officer Chris Woodroofe said on Friday morning, that 120,000 passengers due to arrive or fly had not travelled since Wednesday night.
