Is There a Glitch in Star Wars the Force Unleashed Xbox 360 for destroying the star destroyer

in my experience if you are like me i tried and then failed because the tie fighters kept killing me. and then i didnt play it for like a month. all you have to do is let go of the destroyer whenever the tie fighters come and destroy them with lightning and then grip it again when you are done. do this multiple tmes and you will eventually get the destroyer down to the ground.
PS: this may take 5- 10 mins
