Other mistake: After the "flying" scene, the story cuts back to real time. When it starts to transition back to the flashback, the camera zooms in on a television screen with the fireplace in it. This screen is 1) also used in the beginning of the movie 2) impossible, seeing how there was only one ROV in that room, and it shows the ROV in it. (00:06:15 - 01:20:10)
