UK police can't identify drone model, no end in sight to Gatwick confusion
Sussex Police has received about 50 reports of a drone being flown around the airport since Wednesday evening.
Det Ch Supt Jason Tingley said shooting the drone was discounted earlier but is a "tactical option" and something which is being "continually reviewed".
The Army has been deployed, but it was confirmed the airport would remain shut into Friday, BBC reported.
"We have got some estimations around the size of the drone, what it looks like," Det Ch Supt Tingley said.
"We haven't yet identified the specific make and model of the drone. That will influence our tactical options."
Confirming the airport's closure on Thursday evening, chief operating officer Chris Woodroofe said: "We will review overnight whether there is any potential to open tomorrow." ■
