Question: In 2008, Wayne Singleton and his eight-year-old son, Jaron, were traveling on a bus for a school fi eld trip to Six Flags. Wayne fell asleep on the way, and while he was asleep, the bus became airborne and drove off the road into a wooded area. The bus eventually collided with a tree. Singleton was asleep when the bus went off the road but woke up for the collision. Jaron was awake the whole time but did not understand the situation. Wayne sued the District of Columbia for the negligence of its employee. At the trial, only Wayne and his son were presented as witnesses. They did not call the bus driver or any other passenger or driver as a witness to provide evidence for why the bus went off the road. Due to this lack of evidence, Wayne invoked res ipsa loquitur to infer evidence for the negligence of the driver. The trial court disagreed and granted the District's motion for summary judgment. How do you think the case was ultimately decided on appeal? Why?
