A CAA spokesperson said:
‘The CAA is aware of a possible incident with a drone at Heathrow today (Sunday 17 April) which is subject to investigation by the Metropolitan Police. Safety is our first priority. Anyone operating a drone must do so responsibly and observe all relevant rules and regulations. The rules for flying drones are designed to keep all airspace users safe. It is totally unacceptable to fly drones close to airports and anyone flouting the rules can face severe penalties including imprisonment.
For incidents such as this the CAA would receive a report from an airline within 96 hours.
The CAA’s “dronecode” provides advice on how to fly your drone safely and follow the rules at all times. More information at: www.caa.co.uk/droneaware.
Drone users have to understand that when taking to the skies they are potentially flying close to one of the busiest areas of airspace in the world – a complex system that brings together all manner of aircraft including passenger aeroplanes, military jets, helicopters, gliders and light aircraft.’
