How about Snakes on a Plane lol... I like sci fi movies like Battle Los Angeles and Battleship. Although light on storyline they do give some focus to the aliens, which makes these types of movies more watchable.
I've just been to the DVD shop and I was wondering if you have seen Air Collision, it's a 2011 movie - I think it's one of those low budget ones and was actually told to avoid the particular company that produced that movie and there's also Airline Disaster. Both don't seem to have a high rating at all but I thought I'd throw them out there anyway
On the science fiction note - Serenity is good. It's kinda the sequel to Firefly, a show that unfortunately only got to make one series and I think the series is better than the film, but if it's movies your after.... Star Wars - obviously. The original trilogy is so much better than the prequels are though. I enjoyed the new Star Trek film. And The Island is pretty cool.
