As far back as in the 24th century BC the shepherd Etana wanted to fetch the “plant of birth” from the sky for his childless wife but crashed together with his eagle.

Today, the discussion is mainly focused on green technologies for sustainable flying. How familiar are you with current developments in aviation? Go ahead and test your knowledge.
