What do you think will happen to the sound waves preceding the object when you set the speed of the object equal to the speed of sound? Try it and see! Set the "speed" slider to 1.0 and press "start." Can you explain why the first jet pilots to fly their planes near the speed of sound thought it might be impossible to break the speed of sound (approximately 760 miles per hour)? What do you think was happening to their planes as they approached the speed of sound?
