Some of those 'bird's eye' views are reproduced in a book that is being sold at the moment called 'Stockport from the Air' - I bought a copy at the weekend and its really interesting, its mixes old photos and up to date photos and is good quality. There is a temporary shop opposite the Peel Centre selling the books, and I think you can get them online too.
Just to point out - I have nothing to do with the people that produced the book - I just thought its was a really interesting book to own (even though both mine and my parents houses are just off the photos!)
