Within the last couple of years I watched a movie where some people realize that an invading alien spaceship had crashed in some place like Russia or Siberia, where it's icy most of the time. The only reason the invasion didn't proceed was because the alien ship and alien were frozen.
A group of these people fly in an old cargo plane to the icy location, to search and destroy the alien spaceship and aliens. I can't remember much else, except maybe two of the protagonists were father and son. The movie had to have been made no earlier than 2019. Seems like a lot of people die in the final showdown with the alien, but the two men (father and son?) survive and kill the alien.
