This two-part series focuses primarily on eVTOLs, the technologies making them possible, and how they have evolved from impractical novelties to potentially useful tools for both personal transportation and commercial applications. Part 1 looked at how many of the early human-carrying eVTOL designs were based on technologies originally developed for the relatively simple “multicopter” style drones, which remain popular for many recreational, commercial and military applications.

For vertical operations, the pilot pitches the Axe’s nose upward to a 45-degree angle, which points the thrust generated by its propellers directly downward. Vertical landings are accomplished by gradually transitioning from forward flight to a stable hover. During both transitions, the Axe’s flight-control software handles the trickier aspects of the operation. The motors’ peak output of 280 kW allows it to carry up to 440 lb. worth of crew or cargo.

But the movie’s greatest achievement is that it’s the first, and arguably the best, cautionary tale about the potential hazards of AI, many of which are only becoming apparent to most of us seven decades after its release. Forbidden Planet is set in the 23rd century and opens with the arrival of the United Planets starship C-57D at the distant planet Altair IV (does this sound familiar?).
