In the trailer, I noticed some chemtrails across the sky at about 1:04. I wonder if there's going to be any pilot-able jumbo jets, similar to the ones in IV (you know, the ones that never landed).
Or perhaps a mission strand for a conspiracy theorist (http://en.wikipedia.org/wiki/Chemtrail_conspiracy_theory), à la the Truth.
Who knows, maybe he'll even make a return.
Ehhh?
