Thanks guys for your tips and advice it did clear things up a bit for me. I've came to a conclusion that because of the damaged caused by the 2 engines on the leading edge of the right wing, it led to assymetric LE flaps, generating more lift on the left wing and stalled the right wing and in the end the aircraft rolled violently to the right and crashed because there weren't enough roll and yaw control to balance the aircraft etc etc. My lecturer agreed with me and reckons i'm on the right track. so now i just gotta keep writing it
cheers guys
