This week, it's an underground haunted historical close and an underwater ghost plane!  First up, Felicia takes us on a tour of Mary King's Close - an area of ancient alleyways and abandoned houses under the Edinburgh City Chambers in the historic Old Town area of Edinburgh, Scotland. From plagues to poltergeists, naturally this area has had a reputation for dark misdoings and hauntings since the 17th century, as it soon became "shrouded in myths and urban legends; tales of hauntings and murders abounded." Next, Lauren goes fishing for clues in the Monongahela River with the Mystery of Pittsburgh's "Ghost Bomber" of 1956. How does a 15-foot high B-25 bomber go missing in a 20-foot deep river never to be seen again? Well that's the mystery! Was it carrying dangerous or mysterious cargo that the government wanted gone? A nuclear weapon?! A UFO from Area 51?! To this day, the Ghost Bomber remains one of aviation's murkiest unsolved mysteries that's just plane weird.
