Thank you Camp Freddie for reply in the spirit of things. There's been lots of discussion as to whether the guy in yellow is the actual pilot. This misses the point that someone has still flown a helicopter in this manner.
Yes, Freddie, I was surprised at how close the people are in the final helipad shot. Also as it emerges from the tunnel and the camera pans right, there are people just standing on the pavement.
Some comments on the original webpage hosting the video suggest that the 60's were the golden age of Rio and that it was supposed to be a model for future cities, with a Concorde link to Europe. The roads certainly look new and devoid of vehicles. All this has changed in less than half a lifetime ! What does the future hold?
