When they see it, they start bleeding and things happen including death, electronic malfunction and engulfing the plane in which is leads to aliens taking over the plane.
The alien then takes over all that is living and the people become it even the dead ones. They then end up landing and everyone is infected when they get off the plane after they mimic real humans.
This movie is a good one if you are into horror sci-fi type movies. I hope there is a part two because it pretty much ended with guy getting arrested and trying to explain to the military what happened. I watched this black box thinking it was the series so be mindful. This is the movie.
