in the quest to find a photograph - taken after the Second World War - that contains over forty aircraft in flight, this is the highest quality photograph so far: via this forum thread. I count 49 Sea King, Wessex, Gazelle, and Sea Prince (?) in this formation - which I believe is from the 1975 Royal Naval Air Station Culdrose Air Day.
