The Army has been called in to help as police attempt to find the operators of drones which have shut down Gatwick Airport disrupting the travel plans of more than 110,000 people.
The military were contacted as the hunt for the devices and whoever is operating them becomes more and more desperate with flight cancellations at the UK's second busiest airport continuing to soar.
The runway has been closed almost constantly since two drones were spotted being flown inside the West Sussex airport's perimeter at 9pm on Wednesday.
Police have described the devices as "industrial" models and are treating the incident as "a deliberate act to disrupt the airport".
Some 110,000 people were due to either take off or land at the airport on 760 flights on Thursday. Around 10,000 passengers were affected on Wednesday night.
