Drone technology used in aircraft safety checks
New technology is helping engineers to carry out safety checks on aircraft.
What can take the human eye more than a day to find, a drone can spot in a matter of hours.
The drones are able to create 3D images with millimetre accuracy.
The BBC's Richard Westcott has been to see the technology in action at Luton Airport.
