Capturing aerial drone imagery, in a congested area, can only be done legally if CAA regulations are adhered to. A congested area is defined as "any area of a city, town or settlement which is substantially used for residential, industrial, commercial or recreational purposes." To undertake a drone flight in such an area requires the drone pilot to maintain a distance no less than 50mtrs from any vehicle, person or structure not under the control of the operator throughout the flight. This distance is reduced to 30mtrs during take offs and landings. So when we wanted to capture an aerial photograph of York Crescent, with Bristol Suspension Bridge in the background, it was necessary to undertake a thorough pre-deployment survey of the area. We were lucky to find an extremely helpful and amiable homeowner who kindly allowed us access to his very large garden, in just the right position for us to get the shot. Straight up and straight down, and it was 'in the can!
