Igor Sikorsky a Russian born scientist, engineer, pilot and entrepreneur.

Of Early Aviation – Igor Sikorsky

“We were ignorant, and we were ignorant of the fact that we were ignorant!  This was ignorance squared, and it often led to disaster.”
“My first two machines were built between 1909 and 1910 and were helicopters. The first of these ships refused to leave the ground while the second could lift itself, but refused to lift me.”
Leonardo da Vinci Sketch of a Helicopter – Igor’s Inspiration

1909 H-1, Igor constructed his First helicopter “This machine was a failure to the extent that it could not fly. In other respects it was a very important and necessary stepping stone.”
