I see the WW2 commemorative flight more often than the other aircraft in this flypast because they usually do a flypast on the Queen's birthday and need to get the slower aircraft out of the way fast after they've flown over Buckingham Palace - they curve off north on a route that goes more or less over my house, which is 4km WNW of the palace, so if I remember it's going to happen I try to get out onto the roof and take some pictures. Unfortunately the other aircraft fly much further south from my point of view, and they're rarely visible because the view is blocked other buildings, trees, etc.
This is one I took with my old D90 in 2018 which I'm pretty sure was from the roof - not 100% sure because I somehow managed not to include any buildings or trees that would confirm the location, which isn't easy given they're only visible for about 20-30 seconds.
