I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
This is an urban location with good views of the River Irwell in central Manchester, and across the Manchester cityscape.
My take-off-and-land location was at the mouth of the long-disused Brunswick Wharf / Brunswick Basin (a canal which branched off the river and ran underground). After dark, it was quiet and I saw nobody else while I was there. It is accessible from Water Street M3 4JQ. Walk south past the Marriott Victoria and Albert Hotel, and once past the hotel forecourt follow short footpaths west alongside the disused basin. This leads to a riverside path with some suitable spots to take-off right next to the bascule bridge.
Accessibility: There is no parking on street, but other parking is available nearby and then it's a five-minute walk. The TOAL point was accessible via steps.
Hazards: It's a city-centre environment so there are pedestrians, cars, trains etc, and sometimes boats on the river during the daytime. You may be challenged by security from the hotel or nearby sites, so if concerned about that you may want to notify the police about your flight in advance. Brunswick Basin itself is not well-lit after dark, and there could be anti-social use. During the daytime I would not expect this.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 27/05/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
