“Karl Irbitis was one of the pioneers in aircraft design on the European continent.
The fact that Irbitis designed all these successful aircraft under extremely difficult conditions,
gives reason to believe that more favourable circumstances would have placed him more
in the spotlight, amongst the leading men in the world aviation.”
