The Scary Sky Skeleton

The gang goes off to an airfield to visit Daphne's old school friend Wendy, who's become a stunt pilot. Before they arrive, the Sky Skeleton turns up and scares the crap out of Shaggy and Scooby. Could it be the Airfield owner, who has held the stunt championship for herself for the last few years, and bears a grudge towards Wendy, or maybe it's the enthusiastic Journalist who's just turned up on the scene?
