Professor Nikolajew attracted the attention of the Adventure Club of Europe (ACE) with his momentous claim about the very first flight of manned aviation: According to his research, it was not the Wright brothers who made the glorious maiden flight, but the Eulenstein brothers - in the year 1825, 75 years before the Wrights! As former members of the ACE, the Eulensteins had long been forgotten, which is why it was all the more important that Professor Nikolajew’s research was supported. Defying the ridicule of his colleagues, and with greatest passion, he worked tirelessly from then on to produce the evidence of the feat. A film team documented Professor Nikolajew’s many attempts to get his replicas of Eulenstein's aircraft to fly.
