FOX is airing special tv spots for Super 8, which started Sunday night and supposedly go through Wednesday. If you want to catch one of them yourselves they air at 8/7PM, or just check this post.
Update: These trailers do show a good portion of the train crash scene so if you want to be surprised you may want to skip them.
