Another obviously incomplete lecture manuscript is known as:

"Über den Fortschritt in der Flugtechnik" (About the Progress in Flight Technique).

Through the mention of the drafts of the airshipmen Andreè and Wölfert which were presented at the trade exhibition in Berlin it is known that the manuscript was written in 1895. "What kind of cultural progress could be achieved if we could use the free atmosphere, where no mountains, no woods, no water, no marsh obstruct our movements, for air traffic. You have probably imagined before that borders would lose their relevance completely, because one can't barricade them in the sky. One can hardly imagine that customs duties and wars could then still be possible. The immense progress of world traffic between peoples would make it necessary that the languages mix to a universal one. But it should not be my task to talk about the enormous upheaval in all spheres and to give you an outlook on the future in a way of enthusiasm. We rather want to see today's standard of flight technique in a sober light." An analysis of current interest in balloon technology and of bird flight research followes. The manuscript breaks up before it comes to the topic of the title.
