Three arrests have been made after a group of trespassers sneaked into Doncaster airport and climbed into the cockpit of a plane.
Police were called in after a group, describing themselves as 'urban climbers', filmed themselves breaching airport security to get into the cockpit of a plane.
The group got into an empty hangar to climb into the plane.
Footage of the incident and photographs were shared online.
Airport officials admitted the incident when the footage emerged.
The authorities were informed and airport bosses stressed that the 'safety and security of our passengers' remained their 'number one priority'.
