In Search Of... "Glenn Miller" (1980)
Here's another excellent episode from the fourth season. We start off learning about who musician Glenn Miller was and what made him so popular. We then get into his mysterious disappearance during WWII and hear from several people who believe that there might have been some sort of conspiracy in his plane crash. If you're a fan of Miller or the series then you'll certainly love this episode as once again it does a great job at telling you the story as well as making you wonder what actually happened. The episode works perfectly well as a bio of Miller but the mystery of his death is certainly the most fascinating aspect.
