I remember reading a post here where someone was concerned about accidentally doing a CSC in-flight and someone replied saying they could not imagine what scenario that would happen in... well I found one! I was doing a flyover of a hole on a golf course and wanted to approach the green from the front, descending slowly, and do a nice swing-around clockwise to look back down the fairway. So far I have ↘ ← for the swing around plus descent, but then I realised that I had over-shot the green slightly and needed to move back a wee bit to get it in frame properly. So a little bit of reverse would have given me ↘↙ and a smashed phantom! Or close to it anyhow, as I was not descending rapidly nor would I have reversed rapidly, but it would have been close enough to a full CSC that an errant twitch of the thumbs could have sent it tumbling. Now this actually wouldn't have produced good results anyhow, as looking down at the green from high does not translate well into looking back down the course from low without messing up the shot by moving the camera (c'mon 7th channel....) but the fact is that - rightly or wrongly - I found myself in that situation actually about to offhandedly do a CSC in midair.
