Lawmakers in the UK are scrutinizing airport security after chaos caused by drones at London's Gatwick airport. The drone scare disrupted roughly 140 thousand people's travels over a three day period last week. CGTN's Natalie Powell reports.

These were the scenes at the UK's second busiest airport when flights were suspended for more than 36 hours last week, due to drone sightings close to Gatwick's runway. Flights only resumed once the army had been deployed using unidentified military technology. And the UK says the incident was a deliberate act of sabotage .

THERESA MAY BRITISH PRIME MINISTER "Those who are caught endangering aircraft can face up to five years in prison. And that's legislation that we've already introduced, and actually we're consulting on further aspects of this, including further police powers."

The Metropolitan Police Commissioner however believes the chaos caused by these drones should act as a 'wake up call' to the UK. And this incident has highlighted the real threat drones pose to airports and infrastructure. Some companies are already developing technology to counter these threats. This firm the Netherlands, supported by the Dutch Military Police, has created the DroneCatcher - to safely remove illicit drones from the air.

ARNOUT DE JONG, CEO DELFT DYNAMICS "There is a high risk close to airports, but also when there is a big thing going on, you want to have systems capable of countering drones, could be a terrorist, you don't know what its intentions are."

But it appears catching the perpetrators of the Gatwick incident is proving difficult. Two people arrested have since been released without charge, while the investigating police force has been criticised for not handling their communication response well.There were also some doubts over whether there had been genuine drone activity, as police do not have footage of any drones near the airport, but this has since been quashed by police who say they've had 67 reports of sightings.

NATALIE POWELL LONDON "Gatwick airport has offered a 60 thousand dollar reward for any information leading to the arrest or conviction of those responsible for disrupting flights. But the incident has also exposed failings in Britain's security response to these threats, which will need to be stepped up in future, if further chaos like this is to be avoided.
