As Gatwick slowly returns to normal after Thursday's drone disruption, passengers are still having to make alternative travel plans, which could mean missing part of their holiday.

Labour's shadow transport secretary Andy McDonald said: "We're all relieved that Gatwick has reopened, but the Government now needs to admit that the chaos of the past two days was a consequence of its own failures.

"The Government has neither understood nor fully assessed the risk posed by drones to the UK's national infrastructure. It has not undertaken anything like appropriate contingency planning.

"And it has not prepared properly, despite protective technology being available.

"It's obvious that drones should not be able to get anywhere near an airport before being taken down.

"But the Government has dithered and delayed on regulating drones. Once again, there is a lack of leadership from the Transport Secretary."

Police are still hunting for the drone operator, as thousands of passengers remain stranded.

Sussex Police assistant chief constable Steve Barry said one possibility is that there were multiple drones over Gatwick at any one time.

He added that there had been “dozens” of drone sightings in the past 36 to 48 hours.

Speaking outside Gatwick Airport, Sussex Police's assistant chief constable, Steve Barry, said measures to tackle the drone threat include "technical, sophisticated options to detect and mitigate drone incursions, all the way down to less sophisticated options".

He added: "Even shotguns would be available to officers should the opportunity present itself."

A Norwegian Air spokesman says the airline is now "beginning to operate flights again".

They added: "Due to our aircraft and crew being out of position the return to our normal flying schedule will take some time and as a result not all flights will operate and some delays will occur. Customers should check the status of their flight on Norwegian.com."

The assistant chief constable of Sussex Police Steve Barry would not be drawn on what he believed the motive is for the Gatwick drone operator but said that those responsible could be “high-end” criminals or an individual.

At a media briefing, Sussex Police’s assistant chief constable Steve Barry said there is “no evidence” the Gatwick drone incident was state-sponsored.

The drone which sparked the disruption at Gatwick was last seen at 22:00 last night, Mr Barry added.

Mr Barry added that there was believed to have been sightings of more than one drone.

Police have not managed to capture the drone - so how will they track down its owner?

Drones flying near Gatwick Airport have caused chaos to passengers, but how serious is the offence?

Footage recorded at Gatwick airport appears to show a flying object in the airspace.

A man has told of his devastation at missing his uncle’s wedding in Ghana because of the Gatwick flight chaos.

Garron Akushie-Stevens, 26, was due to travel as part of a four-strong party for the wedding taking place on Christmas Eve.

But when they arrived at the West Sussex airport, they were told by the airline TAP Air Portugal that the flight had been cancelled.

Mr Akushie-Stevens, from Neasden, north-west London, said: “I’m highly disappointed as he’s a close uncle to me.

“It’s unacceptable. I feel traumatised, I feel let down and as if I’ve been thrown to the wolves.”

He added that he was handed a packet of Christmas chocolates by staff.

The BBC contacted airports around the UK to ask whether they were changing their security after the Gatwick drone incident - and, if so, how?

Heathrow – Has increased security patrols around its perimeter to complement the technologies it has at its disposal. New anti-drone technologies are also being trialled.

Luton – A spokesman said the airport “has a number of security measures in place, including increased vigilance and additional police patrols”.

Bristol – The airport’s head of security told the BBC the airport would "take a proactive approach to monitoring any suspicious activity on or around the airport site, including the illegal use of drones”.

London City – A spokesman said the airport was "working with government agencies on solutions to ensure we, and most importantly our passengers, are adequately protected”.

Edinburgh – A spokesman said the airport undertakes regular patrols as it is “but we have stepped up the number of them since yesterday”. They added they are “reviewing those measures in light of the issues at Gatwick and will be working with our partners on that”.

Newcastle – A spokesman said the airport had “contingency plans in place for a range of operational scenarios”, which include "being prepared in the event of a drone flying close to the airfield".

A BA spokesperson told the BBC that they are running a full service at Gatwick today but some flights will be delayed.

A family has told how they have had their Christmas holiday plans ruined by the Gatwick flight disruption.

Kevin and Lisa Haynes, and their daughters Aphea, eight, and 11-year-old Jayda were due to go on a cruise.

But their flight to Madrid was cancelled, meaning they would also miss their connecting plane to Miami.

Mr Haynes, from Wolverhampton, said: “It’s cost us a lot of money. But what can you do about it?

“You can understand the airport’s view. They’ve got to ensure health and safety.”

Who covers the extra costs as flights are disrupted - and other practical questions answered.

Mrs Ford said: “We are back today for a second attempt at going to Lapland. It’s fingers crossed as the kids are really excited.

“We will just have to see what happens. It’s been disappointing but there are people who have had their Christmas plans completely ruined.”
