Jason Wurlitzer was property tycoon Kurt Wurlitzer's twenty-year-old son. When he flew his personal rocket-plane onto a creepy jungle planet, his plane was brought down by dwarfs, and he was kidnapped. Jason was held captive in a cell underground while the dwarfs requested a ransom from his rich father: three million tonnes of uranium.
The Second Doctor, who initially tried to save Jason when he was first captured, came back with a team of experts from across the universe to rescue him. He thanked them all when he was finally saved. (COMIC: Operation Wurlitzer)
