It really depends on what degree of accuracy you're looking for. If it's just crashing a plane, that takes no more competency than crashing a bus. There is software available. It comes up and it's a 757 flight deck. A friend of mine pulled it up and it's Chicago's O'Hare Airport and there is the Sears Tower Building. You might be able to practice this on your home PC.
