The barrier didn't prevent the passage of the spaceship. Khan didn't recognize its model, but its shape reminded him of some of the cargo vehicles seen during his studies.
The spaceship flew slowly and completely stopped when it reached a specific area stretching under the streets on Khan's right. The vehicle didn't actually land anywhere. It only attached its side to a channel-like structure that managed to keep it lifted even after its engines shut down.
Khan couldn't see every detail due to the distance from the landing area, but it wasn't hard to recognize the Orlats. A group of those aliens hurried into the channel and came out a minute later while carrying multiple small boxes.
The Orlats amassed the goods on a rectangular platform near the landing area that shot up as soon as enough boxes gathered. The elevator reached a location right below the streets, where more Orlats promptly got to work to load everything on a big cart.
