“We were ignorant, and we were ignorant of the fact that we were ignorant! This was ignorance squared, and it often led to disaster.”


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.”
