I wasn't sure where to put this, but here goes. There's a show I like, which shall remain nameless. In the second episode a torpedo boat uses a tilted shipwreck as a ramp to launch itself into the air, and fire its torpedoes into the cockpit of a hovering gunship. None of that broke my suspension of disbelief. The ship was just sufficiently tilted to make a believeable ramp. The boat launched high, but not unbelievably high. The torpedoes didn't launch like missiles, but instead tumbled a very short distance through the air, and one of them missed. ect. ect. The thing that broke my suspension of disbelief is the fact that the torpedo boat's propeller was not sheared off when it made the jump. Why is it that we're able to accept some things without a thought, but others pull us completely out of the story? Discuss.
