Amazing Movie but I keep thinking about this ...

Rating: 9/10 (1 July 2014)

I'm addicted to this movie specially the first scene and the last one. i watched these scenes nearly 10 times! sorry for my English first :)
OK, what makes me confused is the following: well, what i understood is that the pilot lost the control of the tail and those little things in the back sticked to the down position which made the plane to dive. and then he rolled it to make that sticked thing to be up so it will do the opposite (trying to elevate the plane). OK that makes sense. but after that he rolled it back again and the plane didn't dive. i really can't understand it and i wish if anybody has an explanation to email me here amranababneh@outlook.com
I'm not an engineer or sth :P i'm a medical student. thanks
