In The Thing, there's a scene where Dr. Blair, played by Wilford Brimley, is examining what I believe is the first half-alien, half-human victim.
The scene switches to showing the harsh weather outside. At this time, two lights can be seen that look like an approaching plane.
Just at the last moment when a plane would be visible, it seems like they stop and turn to the right of the screen. At one point they almost look like two planes' lights.
Were they part of the movie, like a supply plane?
