I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
This is a fascinating area of Manchester with lots of historic and modern architecture and infrastructure, and great views of the city centre.
I've used two take-off-and-landing points:
This is a quite little path down from the main street, nobody else was there for the duration of two flights. I would not use this location late at night as it is unlit and anti-social behaviour could be expected.
This is a canal-side path with benches for seating. It is close to a number of businesses and may only be practical at quiet times. I used it late on a quiet evening and was not approached at all.
Hazards: this is often a busy area for pedestrians. Note that many of the boats on the canal are used as homes, and there are several businesses and domestic buildings in close proximity. There can also be bird-life (seagulls and geese while I was there).
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 14/06/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
