I shared some shots from a brief visit I made to Feltham to get some airliner departures from Heathrow when they were on an easterly flow. Some of the planes turn to the south shortly after takeoff giving you a view that is not quite a topside but is close to it. When photographing them, you are naturally shooting them at an angle as they are climbing quite steeply. However, if you want to play around with the shot afterwards, you can change the impression of the shot quite a lot. Rotate the fuselage until it appears horizontal in the shot and now it looks a lot more like you are flying alongside the aircraft. This is cheaper than sorting out and air to air sortie! Here are a couple of before and after shots to show what I mean.
