I thought about it, and you're right. Anything that DOESN'T require research is too damn easy, for a lot of us, it takes research just to think of a good question that MIGHT take more than a day to get answered. So, I guess as long as it's contained in the movies, even if it's never actually mentioned in the movies (such as the names of the bounty hunters seen in ESB, etc...which is not my question by the way).
As for MY question...Hmmm...
I'll try to make it challenging...
What are the names of the 2 Alliance characters (pilot and gunner) who flew the snowspeeder that first successfully used the towcable and harpoon to down an AT-AT at the battle of Hoth and what was the call number of their speeder?
