Top Gun: The Next Generation
In National Geographic’s new six-part series TOP GUNS: THE NEXT GENERATION, cameras follow a class of Navy and Marine Corps student pilots as they enter the final—and most unforgiving—phase of elite strike fighter training.
It’s six months of high-stakes aerial training, brutal physical demands, and emotional reckoning, where only the top performers earn the chance to fly the Navy’s most coveted aircrafts.
The Hunt For The Chameleon Killer
Exploring all the crimes of Elaine Parent, The Hunt for the Chameleon Killer uncovers every potential victim and determines whether law enforcement is correct in their belief that she was a serial killer. It shows how Parent claimed an interest in numerology, and that she could predict the future with the help of key numbers, to get her victims to divulge their personal details, which she then used to steal their identities. Ultimately, The Hunt for the Chameleon Killer answers the key questions at the very heart of the story: Who was Elaine Parent? And what drove her to commit these crimes?
