People do and they use Drone Scene. It shares the same datasets as Altitude angel and more from other sources. It also has a large number of sites that have been flown by GADC members who have taken a few minutes to give a description, share a picture and detail things such as access and car parking.
Land controlled by the National Trust (restrictive) and the Crown Estates (drone friendly) are two of the many layers. A new feature is showing which councils have drone by-laws in place and what they are. Give it a try. If you are using a mobile make a link to your home screen then it’s always quickly available.
And it’s free!
