Drones are not allowed to fly above 400ft and 500m from the operator and they must be kept in visual sight at all times. Without the permission from the CAA it is illegal to fly over or within 150m of a congested area, this includes roads, towns, festivals etc. Drones are not allowed closer than 50m from an individual unless they have their consent, in other words you can’t go rogue and fly it around people without them saying it’s OK to do so, and you cannot, unless you have permission for the CAA or the airport operator, fly within 5miles of any airport. Given the current affairs with drones and airports it will soon be impossible to fly a drone anyway near an airport.
