Do you know that an Russian inveneted helicopter :)

I don’t think all of the design and development of helicopter can be attributed to a single person. In the past many worked on the project and made some contribution to the design and development of helicopter. In 1910 Igor Sikorsky completed what was started before him in 19th century.

I didn’t know that the Russian engineer was first to design a helicopter that could lift its own weight. I read on the Internet just now. :)

As for the word вертолет it was introduced to Russian language in 1940s The original word used was геликоптер which was borrowed from French who in turn barrowed it from Greek.
