Oh no, I've gone back into a generic topic

Dear Boys and Girls, here is an article in French about an unidentified Sikorsky high-speed helicopter "project"......

The article comes from the 30th June 1961 issue of Les Ailes......

Hello Hesham, used your link, but it led me to a paper about plastic/composite structures ...
Cannot improve the quality, probably it isn't better in the original source, but I stitched
the parts together.

Excellent my dear Jemiba,thank you.

BBC Horizon documentary from 1982, some footage of the S61F 45 mins in... rest of the film is pretty interesting as well...!
